Utility bills are a sizeable part of any household budget. When you live in a cold or warm climate, and especially one with severe summers and winters, your HVAC heating bills can leave you feeling like there’s a hole in your wallet. Some households must even go on level payment plans to afford their bills during the hottest and coldest months. To keep their homes affordable, households need to slash energy costs wherever they can. Did you know that the size of your HVAC unit is one of the biggest factors in heating/cooling costs? That’s why we found the answer to the question, What size HVAC do I need?

What Size HVAC Do I Need?

Determining HVAC size needs relies on calculating the British thermal units (BTU) required to heat/cool your home. Once you have the BTU number, it’s a matter of selecting an HVAC unit with the right BTU rating.

Accurately determining BTUs requires an extensive calculation, which can be performed by an HVAC professional. Though you can guesstimate BTU needs based on square footage, there are too many other factors for the estimate to help you fine tune your HVAC setup and save on your monthly bills. Here are the two steps you must follow to answer the question: What size HVAC do I need?

Step 1

To answer the question, What size HVAC do I need, you first must calculate how many BTUs your home requires to stay adequately heated or cooled. HVAC pros often use a manual calculation to make this determination. This method is preferable because it uses precise measurements to calculate a much more accurate answer.

The manual calculation considers the following factors:

  • The home’s square footage
  • Climate considerations
  • Ductwork
  • Numbers of windows and style
  • Shade/sunlight
  • Insulation
  • Number of residents
  • The effect of heat-generating appliances

Many utility companies will complete an energy audit that determines BTUs needed at no cost to the customer. If your utility company doesn’t provide this service, you can hire an independent energy auditor or an HVAC dealer to conduct the audit. They will produce a report that shows how many BTUs are needed to keep your home comfortable.

It’s also possible to use your home’s square footage to gain a rough estimate of BTU needs. Though more convenient, using square footage just doesn’t provide the accuracy of the manual calculation. Square footage estimates can’t account for factors like climate, window types, insulation, shade/sunlight and other factors unique to your home.

Step 2


With your BTU calculation in hand, it’s time to select the best unit for your home. An HVAC dealer can advise you on the myriad of options. In some cases, your options may be limited by the type of HVAC infrastructure you have and the size of the space where it must fit. Many apartments and condos require a certain model, which unfortunately can eliminate choices that may provide more efficient heating and cooling.

Assuming your choices are not limited, the HVAC dealer can demonstrate the units that suit your BTU size. Often, BTU calculations land inbetween sizes. This should cause no concern, simply go with the bigger size. Having a unit that’s a little larger than needed is the best practice anyway. It ensures adequate heating and cooling and provides some extra capacity should the BTU change. For example, if you need more power for air conditioning because of the loss of shade trees. Also, you are covered for unusually cold- or hot spells.

Getting an excessively large unit should always be avoided. When the units are too large, they heat/cool the home too quickly, resulting in too frequent on/off cycles that cause uneven heating/cooling and higher energy bills.

Pro tip:


Limit the maximum size of the unit to 15% over the BTUs needed for cooling and 40% over the BTUs required for heating. Heat pumps, which handle both heating and cooling, should never be larger that 25% of BTUs.

Central Air Conditioning Tonnage and Size

If you need to install a central air conditioning system, determining tonnage is the first step. When it comes to air conditioning, size is a critical component in selecting the right unit. Selecting a unit that’s too big will cost you dearly every time the monthly electric bill arrives. In short, a 4-ton unit to cool a 3-ton spaceI achieves no increased performance level.

When the AC unit is too big, it cools the home too rapidly. As a result, it shuts off before completing its entire cycle. As a result, warm air seeps back in much quicker, forcing the unit on again too soon. This increased turning on and off shoots your electric bill to the moon.

An AC unit that is too small is even worse. Unless you choose a unit that is many sizes too small, the AC will keep the house nice and cool, but it will run almost constantly. Today’s central AC units are designed to gradually cool the home and then remain shut off for longer periods, which saves energy. When the unit is too small, it pumps most of the day in an effort to keep up, increasing your electric bills. On top of that, the AC components are overtaxed, causing them to wear out faster and costing even more money. The overuse is also bad for the environment.

A right-sized central AC system runs through the cycle as it was designed, resulting in even cooling and maximal efficiency.

Tonnage

The goal of calculating AC size is to determine what tonnage you need from your AC system. Tonnage is a measure of how many BTUs an air conditioner can cool in one hour. Each ton represents 1,000 BTUs per hour cooling capacity, so, for example, a 2-ton air conditioner cools 2,000 BTUs per hour. Residential air conditioners range from 1.5 to 5 tons.

How Much Tonnage Do You Need?

To answer the question, what size HVAC do I need when it comes to AC tonnage, use the following formula for average climates:

Square footage * 30 / 12,000 – 1

Hot and arid climates like the desert Southwest require a different calculation. For these climates, using the following formula to answer the question, “What size HVAC do I need?”

Square footage * 20 /12,000 – 0

Though these calculations are helpful in estimating the tonnage need, a professional manual J report is the best bet. The manual J report, which can be conducted by an HVAC pro through from your electric company or an HVAC dealer, takes into account important factors that are unique to your home. For example, how much shade is around your property, the thickness of installation and the type of windows you have. The manual J report will give you the tonnage number need.

Tips for Saving Energy

Getting the right sized air conditioner is a great first step, but there are many other ways to save on your utility bills. Considering that HVAC typically represents 50% to 60% of utility costs, it’s well worth the effort to shore up your HVAC system for increased performance.

Don’t Skip on Maintenance

Religiously changing the filter extends the life of your HVAC system and helps it run more efficiently. When dust and other particles collect in the coil and other areas, the system must condition more air to meet heating and cooling needs. A fresh filter keeps the system clean.

Programmable Thermostat

You may want to keep the house toasty on a cold winter’s day, but do you really need the heat blasting when you’re under the blankets? Program the thermostat to a lower temperature at night and have it automatically adjust upwards shortly before your wake up time.

Invest in Energy Efficient HVAC Equipment

If your HVAC unit is ten or more years old, new, energy efficient equipment is a great investment. The difference in efficiencies will save you every month and you won’t have to worry about costly repairs for a long time. Energy Star rated models save even more.

Insulate

Conditioned air that seeps out of the house costs you money. Adding insulation to walls, windows, pipes, ducts and outlets keep the warm of cool air inside and lead your HVAC system to work less.

Utility bills leave many households tapped out at the end of the month. Stop the cycle of energy inefficiency that has the money seeping out of your bank account by installing new, energy efficient HVAC equipment. Before selecting which HVAC unit to buy, make sure to get a manual J report or accurate BTU estimate. With the accurate BTU or tonnage number, you will know exactly what size unit you need. By having the right-sized unit and practicing energy saving techniques, your home will be more comfortable than ever for less cost.

Freon Leak Detector: Everything You Need to Know

If you think you need a Freon leak detector, then our guide will help you determine which one meets your prerequisites. Prolonged exposure to Freon can lead to lung fluid buildup, lung failure, heart issues, brain damage, and even death. If your HVAC unit is placed outside and you think you are safe from all these risks, think again, since it can easily enter your home.

It’s true that Freon is a heavy gas and will pool at ground level, but this still means it’s hazardous for children and pets. In addition, a refrigerant leak can raise your energy bills as much as 35%. Here are the main types of Freon leak detectors and their advantages and disadvantages:

an example of a freon leak detector

Professional Freon Leak Detectors:
Types and Features

Before jumping into the whole refrigerant leak detection equipment discussion, we want to mention that “Freon detection” generally refers to identifying all types of refrigerants.

Here are the most common and the most efficient methods to detect Freon leaks:

Liquid Detector

You can easily create a liquid Freon leak detector at home, by mixing soap or laundry detergent with water. Apply the resulting substance on piping and wait for bubbles to appear. That means you localized the leak and can proceed to seal it tight. This method is widely used by amateurs and professionals. However, you can also purchase liquid Freon leak detectors that are ready-made.

Pros 

  • Very cheap.
  • Easy to make and use.

Cons 

  • Not suitable for inaccessible spaces.
  • Not as accurate as other methods.
  • The ready-made ones have little to no advantages over homemade ones.

Note: Soapy solutions are best used together with other detection methods.

If you already tried it and didn’t consider the old soapy water a reliable Freon leak detection method, you have a few other options available. These are manufactured and designed specifically for this purpose, thus being reliable and precise.

Infrared Detector

These devices use infrared sensors to detect any refrigerant leaks in your home. They smartly use refrigerants’ different reflectivity to infrared radiation to give accurate results in real time. An infrared Freon leak detection device has an accuracy of +/- 1.8°F for temperatures between 32 and 212 degrees Fahrenheit.

Pros 

  • Instant results.
  • Can detect R404A, R407C, R410A, R134A, R417A, R422A, R507A, R143A, R125, and R245fa refrigerants.
  • Highly accurate if used within their maximum efficiency temperature range.
  • No risk of false positives due to moisture, oil, or gas leaks.
  • Can be used within a minute from starting the device.

Cons

  • Naturally, it cannot be used to detect leaks from areas that are not visible.
  • Their accuracy drops in environments colder than 32 and hotter than 212 degrees Fahrenheit.
  • They are almost useless in environments colder than -4 or hotter than 932 degrees Fahrenheit.

Electronic Detector

There are 2 types of electronic Freon leak detectors available: Negative corona and heated diode devices. Negative corona Freon leak detectors create a high voltage electric arc that is sensitive to refrigerants. When the electric corona detects Freon leaks, the device rings an alarm to let you know.  Heated diode Freon leak detectors use heat to break refrigerant molecules apart into Fluorine and Chlorine ions, which can be detected by heated diodes.

These devices have been around for a few decades, and impressed professionals from the start with their accuracy and newer models are much more precise.

Pros 

  • Can detect leaks in inaccessible areas.
  • They are more precise as technology advances.

Cons 

  • Negative corona electronic Freon leak detectors can malfunction in areas with high concentrations of refrigerant. This has been a problem ever since the beginning and, although significant progress has been made, it can still affect their functioning today.
  • False alarms are also likely when other chemicals are present in the air with both types of electronic detectors.
  • They have a fairly short range.

Fluorescent Dye Detector

Many professionals choose light-responsive dyes instead of soapy solutions to detect Freon leaks. These can be injected into the refrigeration system and is carried by the refrigerant through piping. Then, you can use a UV light to see where the dye leaked out of the system. This method is considered the best Freon leak detector at the moment.

Pros 

  • Highly accurate.
  • They are not affected by other chemicals.
  • No false positives.
  • They pose no health threats.

Cons 

  • They cannot be used for larger industrial systems or car ACs since visibility is a must.
  • Depending on the size of your system and the diameter of the puncture, it can take up to a few hours or even days to see results.

Halide Torch as a Detector

Halide torches can be used to detect Freon leaks. Chlorine-based refrigerants will change the flame’s color from blue to green. They use a probe hose to draw in air, which is then exposed to a copper reactor plate that has been previously heated.

Pros 

  • This method shows instant results.
  • Halide torches make it easier to locate leaks.

Cons 

  • It can only detect CFCs (chlorofluorocarbon-based refrigerants) and HCFCs (hydrochlorofluorocarbon-based ones).
  • It uses an open flame, which can be dangerous in some environments.
  • Many things can interfere with their accuracy: Wind can make it impossible for the device to collect the gas, thus leading to false negatives.
  • In addition, direct sunlight can make changes in the flame’s color hard to observe.

Ultrasonic Detector

These detectors are high precision systems that detect seal failures and pipe punctures in compressed air and gas systems. An ultrasonic leak detection device identifies the high-frequency noise refrigerants produce when leaking. They can accurately detect leaks up to 65 feet away and make it easy to identify the source thanks to an integrated point sight.

In addition, they can use a laser pointer to accurately detect leaks in areas with restricted access. Many have a transparent reflector, which offers precision without obstructing visibility.

Pros 

  • Equipped with a highly-sensitive detection sensor.
  • Extremely precise in localizing the Freon leak thanks to visual stimuli.
  • Long-distance Freon leak detection.

Cons 

  • Their accuracy is not satisfactory when used in noisy environments. Although many have features that prevent background noise from interfering with the results, it still affects the final result.

Note: Ultrasonic refrigerant leak detectors can be used together with a soapy solution to increase their precision. The sound of bubbles bursting will be easier to detect by these devices.

Other Tips & Tricks

If none of these methods identified a Freon leak, you seem to be safe. However, if you still suspect something might be wrong with your appliance’s refrigerant piping, you can perform a pressure test. For this, you will need a tank of pressurized dry nitrogen. It should go without saying the gas should be oxygen-free, but we want to highlight this aspect anyway. If you use a soapy solution, a 10-bar nitrogen flow should be enough to make the liquid bubble up.

In addition, keep the following in mind:

  • Never stop investigating after finding a leak. Check the whole system since leaks and punctures are most often caused by wear.
  • Choose high-quality piping and joints. These are less likely to wear out and will last longer.
  • Cap all valves. Uncapped ones are the most common source of refrigerant leakage.
  • Never place appliances that use refrigerant in unstable areas. Vibrations, physical shock, or chafing will deteriorate the piping which will, in time, start to leak.
  • Never ignore maintenance or try to reduce costs by choosing cheap repair services. You might get lucky by avoiding maintenance and professional repair services, but not for long.

Choosing the Best Leak Detector

Keep the below in mind to ensure you get the best value from the freon leak detector.

Detecting the Types of Refrigerants

To find the most suitable leak detector, one has to determine the refrigerant types to handle. That machine has to detect all of the refrigerants. The important thing to remember is that a detector that can detect many refrigerants can cost more than the ones that identify leaks of common refrigerants. Checking one’s field application and expertise is important for that.

Working Speed

Everybody knows that time is money. Spending a lot of time on finding leaks with an inappropriate detector will frustrate the buyer and waste their time, so identifying leaks immediately is crucial. The buyer should choose a model that has good-quality sensors, has less warm-up time, as well as features that quickly detect the leak. Choosing the top brands is the safer option, as opposed to risking time for money on the cheap brands.

Sensors

Detectors come with different types of sensors to identify the leak in the HVAC system. The best detector comes with good sensor quality and durability. The better the quality of the sensor, the higher the price.

Battery

The battery of the detector is another crucial aspect that buyers must examine. Having a good detector is useless if the battery lasts for a short period. The minimum prescribed time for a battery to last is a full day so that the user can get the job done efficiently. Modern leak detectors contain rechargeable batteries, helping the buyer save money and time from frequently purchasing new ones.

Warranty

A broken detector won’t help anyone, so make sure that the leak detector contains a warranty. Although top brands provide good-quality HVAC tools that last for a long period of time, the buyer needs to determine the warranty period since the detector can malfunction. It happens even to the top brands.

Freon Leak Monitoring Systems

If you want to make sure a future refrigerant leak will not go unnoticed, a multi-point refrigerant monitor is what you need. These use audio and visual signals to let you know when a leak has been detected. Here’s what to keep in mind when looking for a permanent refrigerant monitoring system:

  • The refrigerants your appliances use should be the most important factor. You don’t want to end up with a device that only detects CFCs and HCFCs when your fridge has HFC.
  • The device’s placement should be the next aspect you think about. The main unit should be placed in a highly visible spot in your home – like the hallway. At least one sensor should be right next to the appliances that use refrigerants.
  • Keep in mind that air conditioners or heat pumps with fans will direct the air in a certain direction.

Freon Leak Detector Final Thoughts

Please don’t try to install these devices by yourself unless you are a specialized technician. Your family’s health and lives are at stake, so cutting corners should not be an option with a freon leak detector. Never hesitate to reach out to us. You can email us with your questions or queries.

How To Test a Thermocouple: The Easy Multimeter Way

Most natural gas-based appliances such as water heaters, stoves, and furnaces use a thermocouple. This part acts as a safety shut-off device to prevent harmful gas leakage if the pilot light goes out. Knowing how to test a thermocouple when an appliance malfunctions is a vital part of the repair process. Even though standing pilot lights have become somewhat obsolete in recent years, due to the advent of direct ignition technology, there are lots of older, fully serviceable equipment still in use today that use a pilot light, and thus have a thermocouple. Testing one with a multimeter is a job most DIYer’s can do with ease.

thermocouples different types

728x90 Get $50 Off Every Home Warranty

Defining a Thermocouple

Before starting the test procedures, a brief description of what a thermocouple is, and how it works is helpful. A thermocouple is a type of electrical device know as a transducer, and in various forms, is found in everything from small toasters to massive industrial kilns. It basically converts the temperature it senses into a certain measure of DC voltage. There are at least two distinctly different metals inside the part that form two separate junctions. The live (hot) junction is connected to the part where temperature needs to be monitored. The base (cold) junction is either kept open, or is connected to a known temperature source as a point of reference. The difference in temperature between the hot and cold junctions is then converted into a measurable voltage.

Let the Testing Begin!

Knowing how to test a thermocouple with a multimeter is an important step in diagnosing why a pilot light goes out, or won’t ignite at all. Before staring the tests, be sure to thoroughly clean the part first, to eliminate any dust or carbon buildup that might have contributed to it’s failure. The equipment needed to perform the first set of basic open circuit checks are simply a multimeter (either digital or analog), and a pair of double-ended alligator clips.

  1. Using a digital multimeter, turn it to the millivolt (mV) scale on the DC voltage range.
  2. With the alligator clip wires in place on the meter lead ends, clip one test wire to the gas valve (source) and the other one on the exposed copper wire leading to the thermocouple.
  3. Now light the pilot light by turning the on/off switch to “pilot”, and then push down on the pilot valve opening button.
  4. Hold everything in place for up to a minute to obtain the proper reading. The meter should show about 30 mV +/-5mV.

In-depth Tests

If the reading is found to be proper, then most likely the thermocouple can be ruled out as a source of the problem. However, before you call the service pros in, and if you are game, there is a second, slightly more involved test using the same multimeter and clips as before. These tests are known as closed cicuit, and will give you a more thorough assessment of how to test a thermocouple, as well as possibly revealing any other underlying issues such as draft/flue problems, fuel pressure, and gas valve failure. The use of a special screw-in adapter available through most HVAC dealers is the only additional piece of equipment you will need. It will probably amaze and confuse them to encounter such a dedicated DIYer!

  1. The first measurement will check the millivolts drawn by the electromagnetic coil inside the thermocouple. With the pilot light off, and the adapter in place on the thermocouple, a reading of 15 mV should be obtained.
  2. The second measurement can now be made with the pilot light on, introducing a certain “load”. This is mainly to determine if the cold junction portion of the unit is being altered by other heat factors. If the flame is proper, the reading should be about the same as before (15 mV).
  3. The final test is to see how the magnet reacts to pilot light blow-out. Maximum drop-out time is around 3 minutes, with 1.5 minutes being the norm. If the part is good, the voltage with drop to 1-2 millivolts, and there will an audible “click” when the magnet valve shuts.

Thermocouple as a Test-Bed

Since most commercial thermocouples are relatively inexpensive, a case could be made for not bothering at all with the above closed circuit tests, and just go ahead and replace it. However, this would be a big mistake, because how you test a thermocouple can lead to a better understanding of why your appliance failed in the first place. When the part is blindly replaced without knowing the real reasons for failure, it isn’t fixing the original problem.

One of the best ways to get to the root of thermocouple malfunction, while at the same time determining the efficiency of your appliance, is to examine the pilot flame, and it’s relation to the tip of the thermocouple. When the flame is adjusted for optimal performance, it should envelop the upper 1/2 to 3/8″ of the unit, and the tip should glow a “dull-red” color. Anything brighter than a soft, blue flame will tend to heat the tip excessively to a “cherry-red” color, and eventually cause the tip to weld together, and the part to fail. Particular attention should be given to the cold junction portion of the the thermocouple, as it is highly susceptible to any higher temperatures resulting from an improperly adjusted flame.

Precautions During Testing

Safety concerns linked to the above tests mostly relate to the nature and volatility of natural gas. It’s a good idea to perform these tests with adequate ventilation in place, preferably with fresh air flow-through. Extra care should taken when reconnecting the thermocouple fittings to prevent any cross-threading. To be sure there are no gas leaks associated with an improperly tightened fitting, you can use soapy water to check for any bubbles after the gas is turned back on.

Finishing Up

Even though they are fairly cheap to replace, it’s important to know how to test a thermocouple to expose any other problem areas beyond the part itself. Knowing how to perform even a simple function test can give you a good idea whether your appliance just needs an inexpensive repair, or a more costly fix is in order. You can then decide what course of action to take, and be better prepared for the eventual repair/replacement that follows. Being able to troubleshoot any appliance these days can be quite a rewarding and empowering experience!

How to Prevent Condensation on AC Ducts: 6 Steps

Sweating air conditioning ductwork is a significant issue when summers are warm and humid. The cause is simple: The air inside the ducts is cool, and moisture from humid air outside it condenses on AC ductwork like moisture on a glass of iced tea. Condensation on AC ducts is both the symptom of solvable problems and the cause of secondary trouble that can have serious consequences for your home and your health.

This guide gives clear steps to solving problems with condensation on AC ducts so that it does not return.

728x90 Get $50 Off Every Home Warranty

condenser unit from ac

Why You Might Need to Prevent Condensation on AC Ducts

Condensation on AC ducts demonstrates there is one or more repair issues in your HVAC system and/or your home. Solutions are available below, so you can fix those that apply to your situation:

  • Exposed ductwork isn’t insulated;
  • There are gaps in ductwork that allow cold air to escape and promote condensation in spots;
  • Dirty furnace or air handler filters are slowing the flow of air;
  • The ductwork is running in space that is too humid;
  • The blower motor isn’t moving air as rapidly as it should.

Here are secondary reasons to prevent condensation on AC ducts. The moisture:

  • Promotes mold and mildew that causes odors and is a health risk to people and pets;
  • Stains and damages drywall;
  • Wets wood framing causing rot and attracting insects that feed on it;
  • Wets insulation, compacting it and lowering its effectiveness.

Tools & Materials Needed to Prevent Sweating Ducts

That’s a troubling list! The good news is that you can fix the issues. The tools and materials are grouped by the problem they solve:

  • Leaking ducts: Fiberglass mesh tape, mastic duct sealer, chip brush or cheap paintbrush;
  • Non-insulated ducts: Duct wrap and cloth duct tape;
  • Dirty filters: New furnace or air handler filters;
  • Damp basement or crawlspace: Vapor barrier, fiberglass or foam insulation and a dehumidifier;
  • Humid attic: Soffit, gable, ridge and roof vents, circular or jig saw, drill, screws, flashing and roofing tar;
  • Inadequate airflow: New blower motor, if your current motor can’t be adjusted or repaired.

How to Prevent Condensation on AC Ducts in 6 Steps

Rather than sequential steps, these steps start with basics and go to specifics.

1. Find and Repair Loose Joints in Exposed Ductwork

Visually inspect seams or feel for air leaks and listen for air whistling through the seams with the blower fan running. Spread mastic on loose seams and joints using the cheap brush. Then, reinforce it with fiberglass mesh tape pressed into the mastic.

Cover the tape with a topcoat of mastic.

2. Insulate Exposed Ducts

Wrap the entire duct, when possible, or cover the exposed surfaces. Cover the seams of the wrap with cloth-reinforced vinyl duct tape to ensure it remaining in place long-term.

The US Department of Energy recommends insulating ductwork to reduce energy loss and energy costs, even if condensation isn’t an issue.

3. Clean or Replace Dirty Filters

Dirty filters slow the flow of air and keep cold air in the ducts longer than it should be. Meanwhile, it is promoting condensation on AC ducts.

4. Address Damp Basement or Crawlspace Issues

Cover a dirt floor with a vapor barrier. Seal gaps around pipes and vents with fiberglass batt insulation or spray foam insulation.

Persistent humidity problems below grade require a dehumidifier, preferably one that can drain into a floor drain.

5. Vent the Attic

Attics need to breathe. Otherwise, moist air will cause mold and rot and ruin insulation in addition to causing condensation on AC ducts. Installing vents is a challenging DIY project for most homeowners. Roofers and siding contractors are your best options for pro installation.

  • Make sure existing soffit vents are not covered by insulation;
  • Install soffit vents between rafter tails by cutting holes in the plywood soffit and securing the vents with screws;
  • Install gable vents by cutting the hole through the siding and sheathing from the outside. Use the template included with most gable vents, and securing the vent with screws;
  • If your home has a hip roof instead of gables, install roof vents every 20-30 linear feet near the ridge. You can do this by cutting holes in the sheathing and roofing material, securing the vents and using flashing and roof cement to prevent leaks;
  • Install ridge vent by removing the ridge cap shingles, nailing down the ridge vent and reinstalling the ridge cap.

6. Adjust or Replace the Blower Motor

An HVAC technician can adjust multi-speed and variable-speed blower motors to meet the ductwork’s airflow requirements. The technician can also repair or replace the blower as necessary.

Caution Notes

  • If your attic has exposed rafters, walk on them or lay a board across them to walk on. If you step between rafters, you’re likely to damage the drywall below you or possibly fall through the ceiling.
  • Unless you have excellent experience with working on ladders and roofs, installing gable vents, ridge vents and roof vents are jobs better left to professionals.
  • Finally, do not attempt to adjust your blower motor. Possible problems include electric shock, injury caused by the fan rotating at more than 1,000 rpm and damage to the blower motor, fan or other furnace parts.

More Ways to Prevent Duct Condensation

If your ducts are insulated, condensation won’t form on them. Until you complete that project, two tips will help reduce condensation on AC ducts.

  1. First, keep your thermostat set at 75F or higher when in air conditioning mode. The colder the air is in the ductwork, the more likely condensation will form. So, go easy on the AC.
  2. Secondly, if your HVAC system and thermostat have a fan-on mode, use it when humidity is high. Keeping the air flowing over the cold AC coil, even when the AC compressor isn’t running, increases dehumidification. The reduces condensation and keeps your home more comfortable too.

Troubleshooting AC Compressor: How to Find the Most Common Issues

These troubleshooting AC compressor tips will assist you in determining if the compressor is the problem.

If so, let’s see together what the specific issue might be.

Why You Might Need AC Compressor Troubleshooting Tips

If your central air conditioner isn’t working at all or is not adequately cooling your home, it is easy to suspect the compressor because it is the heart of central air conditioning. An AC compressor circulates refrigerant. This is the substance that captures heat inside your home and dumps it outside to cool indoor air.

However, compressors are often blamed when issues like these are causing the problem:

  • The circuit is off: Check the circuit in the electrical box and the one mounted on a wall near the condensing unit. A circuit that continues to trip indicates a wire or compressor problem.
  • Furnace/air handler filter: A heavily clogged filter can prevent the airflow enough for adequate cooling.
  • Iced up indoor coil: If the indoor coil is dirty, it will eventually stop the transfer of heat and cause the unit to freeze up. Turn off the AC, and run the system in fan-only mode until the ice melts. Clean the coil, and restart the system.
  • Condenser fan: With the power on, set the thermostat to AC with a set point below the home’s indoor temperature. Check to see if the condenser fan at the top of the condensing unit starts. A condenser fan motor that is locked up will prevent the compressor from starting.

Tools to Keep in Mind

The main tool used to check AC condenser components is an electric multimeter. Troubleshooting AC compressor wiring requires one. If you have a multimeter and know how to use it, locate the C, R and S terminals. Check for continuity between C & R, C & S and R & S. Resistance should be less than 30ohms.

While checking continuity, look for obvious signs of loose, broken, chewed or burned wiring. If there’s continuity and no obvious wiring issues, then troubleshooting AC compressor issues is the next step.

Troubleshooting AC Compressor Problems in 5 Steps

Here are common AC compressor problems and what causes them.

1. Check Fuses and Wiring

Symptom: The AC turns on and off frequently.

Solution: Known as hard starting and short cycling, this problem prohibits adequate cooling and will quickly ruin the compressor. Internal fuses and faulty wiring are the most common causes of hard starting. If you’ve ruled out those causes, adding a hard-start capacitator that gives the compressor additional torque to get started might work. These devices are helpful when an aging capacitor needs a boost. Moreover, installing one can delay the need to replace the unit for several years.

2. Check the Start Capacitor

Symptom: The compressor won’t start or stops shortly after starting.

Solution: The most common cause of this issues is a failed start capacitor. Replacing it is one of the simpler AC compressor repair issues. If replacing the capacitator doesn’t help, the compressor motor is probably wearing out. If the problem is that a fuse or circuit is being tripped, then repair is possible. Also, if not protected by fuse or circuit, the compressor will soon burn out or lock up. Then, the compressor or entire condensing unit will need replacing.

3. Check Refrigerant Level

Symptom: The unit isn’t cooling sufficiently.

Solution: If you’ve already checked the filter and evaporator coil, then the system might not have sufficient refrigerant charge. A leak is the most common cause of this issue. Troubleshooting AC compressor leaks is difficult without training and the right equipment. Repairing and recharging the system requires a refrigerant handling license.

4. Check Pressure Levels

Symptom: Inadequate cooling and/or short cycles because pressurization is too high or low.

Solution: Excessive suction pressure and low discharge pressure prevent proper circulation of refrigerant. So, it can’t remove enough heat to keep up with cooling demand. The pressure levels must be checked, and pressure switches or valves will likely require replacing.

5. Replace the Compressor

Symptom: The compressor runs but doesn’t cool.

Solution: If everything seems to be working normally, but the AC isn’t making cold air, a broken valve in the compressor is a likely cause. It can’t be diagnosed, but is usually determined to be the issue when everything else is ruled out.

Caution Notes

Working on equipment powered by electricity includes the risk of shock causing injury or death. Turn off the circuit when inspecting your condensing unit and compressor for loose, burned or chewed wiring or if you choose to attempt a DIY repair. When working on powered equipment, always use insulated tools to prevent shock.

You won’t be able to buy refrigerant. As we eluded to, EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act require that:

Technicians who maintain, service, repair, or dispose of equipment that could release ozone depleting refrigerants into the atmosphere must be certified.

It is illegal to sell refrigerant to anyone who does not have a certificate.

Replacing the Compressor vs. the Entire Unit

A few manufacturers like Goodman and Amana offer warranties that provide replacement of the entire condensing unit if the compressor fails, not just compressor replacement. However, most do not, and even if the compressor is under warranty, labor costs usually are not covered. If your compressor has failed, a better option than repair might be to replace the entire central air conditioner. This gives you the opportunity to select a unit with higher efficiency and superior indoor climate control.

An HVAC representative can estimate the cost of the repair and the cost to replace the condensing unit. We hope this assists you in finding a quick fix or deciding to call an HVAC technician for repair estimates. Troubleshooting AC compressor problems is complicated. So, perhaps your friends and followers would benefit if you share this information with them.

How to Light a Water Heater with Electronic Pilot

This guide explains in detail how to light a water heater with electronic pilot when starting a new unit or restarting one after repairs or service.

If you’re unsure what type water heater you have, the Tools & Specs to Keep in Mind section will assist you in determining if your water heater has an electronic pilot. There are tips for keeping you safe when working with gas too.

728x90 Get $50 Off Every Home Warranty

how to light a water heater with electronic pilot

Why You Might Need to Light a Water Heater

The pilot needs to be lit when:

  • A newly installed unit is first started;
  • The gas has been shut off for repair or service;
  • The water heater stops heating for no apparent reason.

If the last scenario occurs, check that the gas valve handle is parallel to the gas line to indicate it is in the on position. Then, look for a small blue pilot flame in the small window at the bottom of the heater.

If there is no flame and the gas is on, the steps below describe how to light a water heater with electronic pilot. If the pilot is on and the dial is set to hot or one of the hotter settings but the unit still isn’t firing to make hot water, your problem is more likely the gas valve, thermocouple or thermostat and should be diagnosed by a professional.

Tools & Specs to Keep in Mind

Water heaters are fired in one of three ways. So, knowing the type you have is essential to lighting it:

  1. Standing pilot, electronically lit: Many newer water heaters require that you know how to light a water heater with electronic pilot. They have a gas control that looks like this one made by Honeywell. Look for a status light that blinks when the pilot is lit and a small igniter button, possibly with a lightning bolt symbol next to it.
  2. Standing pilot, manually lit: If your water heater is quite old, it might not have an electronic pilot. There will be no status light or ignition button. We recommend you contact an HVAC company that repairs old water heaters for information on manually lighting the pilot or to discuss replacing the water heater.
  3. Electronic ignition without a pilot: Some newer units don’t have standing pilot light, that is, one that is always lit. They fire only when water heating is ncessary. Clues that you have one of these models are that it is newer and does not have an ignition button. If the unit isn’t lighting, it is probably a faulty thermocouple or gas control valve.

How to Light a Water Heater with Electronic Pilot in 6 Steps

If you’re sure your water heater has an electronic pilot (type 1 above), locate its gas control assembly. It is a box attached near the bottom of the unit with a rotating control knob or dial, igniter button, status window, wiring and the gas line attached.

Here are step-by-step instructions for how to light a water heater with electronic pilot:

  1. If the water heater has electrical wiring for a fan or other function, then make sure its circuit is on;
  2. Turn the gas valve to the on position, if necessary;
  3. Rotate the gas-control knob or dial to the pilot position;
  4. Depress the knob. Then, hold it down while completing the next step;
  5. Press the ignition button about once per second. Take this action until you see the status light begin to blink every few seconds. This indicates that the pilot is lit. The process that takes up to 60 seconds in a newly installed unit;
  6. Once the pilot is lit (its blue flame can be seen through the small observation window), turn the knob to the hot position or a hotter setting, if you prefer. Then, listen or look for the gas burner to fire.

If the burner stays lit, you know how to light a water heater with electronic pilot!

Bonus Tips

If the water heater doesn’t fire, there are two more tips that might solve the problem.

  • Sometimes, the pilot will go out before you can turn the knob to one of the water temperature settings. This is because the thermocouple hasn’t heated sufficiently. If that happens, wait 10 seconds before adjusting the knob from pilot to a temperature setting.
  • If repeated attempts to light the pilot and water heater fail, look for a small reset button at the base of the unit with wiring to it. Also, if your water heater has one, press and hold it for five seconds. Then, retry the process.

Caution Notes

Never try to light an electronic pilot with mechanical means such as a match or barbecue lighter. If you can’t get an electronic pilot lighted using the steps below, the control assembly might have to be replaced before attempting to use the appliance.

Before starting any gas appliance, check the gas connection to make sure it tight. NEVER check for a gas leak with a flame. Mix a few drops of water with a few drops of liquid dish detergent, and apply the solution to the gas connection. View the connection from all angles. Bubbles in the solution indicate a gas leak. If bubbles develop, tighten the connection, and test it again.  Also, check to ensure that the installer wrapped the pipe with gas-sealing PTFE tape, which is very thin and yellow. If you don’t see it, turn off the gas, disconnect the line and add the tape before reconnecting and testing the line.

If a gas leak persists, turn off the gas, air out the space and call an HVAC professional for assistance.

HVAC Training 101: Your Potential Career Path

The statistics paint a compelling picture: This is a good time to consider an HVAC training and explore the many careers in HVAC and refrigeration.

The outstanding job prospects, good pay and interesting work are among the top reasons HVAC-R is a career path many are already looking into.

728x90 Get $50 Off Every Home Warranty

Employment of heating, air conditioning, and refrigeration mechanics and installers is projected to grow 14 percent from 2014 to 2024, much faster than the average for all occupations.

The above data is according to the Bureau of Labor and Statistics. The BLS predicts that nearly 40,000 jobs will be added in the industry during that decade, with opportunities across the United States.

hvac training

What Does an HVAC Career Offer You?

Let’s look at the pros and cons of getting HVAC training and pursuing an HVAC career. Below you can see the advantages.

1. Outstanding Job Outlook

The 14 percent job growth expected through 2024 is a top reason for considering HVAC training. See Best Options below for a breakdown of top jobs within this sector.

2. Good Pay

The median income is $45,910 per year based on an hourly wage of $22.07 (BLS statistics).

3. Mobility

This sector is experiencing job growth across the country, though the most jobs opening for those with HVAC training are east of the Mississippi and in the South. So, you’ll have options for finding a job where you want to live. Interestingly, places like North Dakota and Montana have fewer job openings than densely populated areas. But wages are higher because of the scarcity of trained HVAC professionals.

There are tens of thousands of job openings outside the US too, if you’re the adventurous type that would like to see the world while building a career and earning good pay.

4. Job Diversity

While most jobs are in installation, repair and maintenance, there are many related fields that require HVAC training. Even as an HVAC tech, each repair or installation job is a new setting. So, you’re never stuck in one location day after day.

If the hands-on work isn’t for you, the HVAC industry needs:

  • Managers;
  • Sales pros;
  • System designers;
  • Customer service representatives.

5. Accessibility to the Career

HVAC training is not long or expensive compared with many other professions. Basic HVAC training and certification programs take as little as six months. Most HVAC training programs are 10-12 months. Those offering associate’s degrees are 18-24 months.

HVAC tuition costs for a basic certificate program average $6,000 to $9,000 and $17,000 to $30,000 for an Associate’s degree in HVAC. Many local trade schools and community colleges have HVAC programs, so moving away from home to get the education probably isn’t necessary.

6. Innovation

The rising global demand for ecofriendly, efficient heating, air conditioning and refrigeration makes this an exciting time to be part of the industry. Innovation is occurring rapidly in technologies such as:

  • Variable-speed compressors;
  • Smart homes/automated homes;
  • Geothermal heating and cooling;
  • Variable refrigerant flow (VRF) systems being adapted for residential use in addition to their commercial applications.

If you want to be involved in an industry that is having a positive impact on the planet and on individual homes, the HVAC-R meets that criteria.

The Cons Are:

  • Some HVAC program graduates find it hard to get that first job without experience. So, it makes sense to get training from a school that offers internships or apprenticeships;
  • The job can be physically demanding, for example when you’re hauling an old furnace out of a basement or are on your knees for hours installing an air handler in crawlspace;
  • Long work hours during peak times in summer and winter. But the upside is overtime pay for those hours;
  • Many local heating and air conditioning companies offer 24-hour emergency service. So, there might be times you’re called out in the middle of the night or on a weekend to make a repair. However, technicians often receive premium pay when on-call and making emergency repairs;
  • Technicians working for small, local heating and cooling companies don’t have as many career-advancement opportunities as those working for large service companies. That’s why having a robust education and NATE certification (see below) are recommended.

What Skills Do You Need to Be an HVAC Technician?

Generally, you should be comfortable using hand tools and enjoy working with mechanical systems. This translates into taking machinery apart, repairing it and putting it back together. The specific HVAC technician skills you must have are also those that HVAC training programs provide. These include expertise and experience in:

  • EPA 608 certification and R-410a refrigerant certification;
  • Climate control systems;
  • Thermostatic controls;
  • Electrical wiring;
  • Air conditioning and heat pump systems;
  • Boilers;
  • HVAC troubleshooting, installation, maintenance and repair;
  • Refrigerant system recharging;
  • Warm-air heat systems;
  • Energy-efficient/green HVAC technology;
  • Refrigeration systems and control (If you want to work in refrigeration).

Six-month programs don’t cover all these bases. The more education and training you have, the better your entry-level job prospects will be, the higher your wages will be and the faster you will be able to advance in your career. Our post on HVAC Certification includes a list of schools offering HVAC training and information about each program.

Also plan to become NATE-certified. NATE stands for North American Technician Excellence. It is a professional organization that offers testing in basic HVAC knowledge and skills and in specialty fields within the industry. Certifications include:

  • Work-Ready certificate;
  • HVAC Support Technician certificate;
  • Professional certificate.

It also has specialties in:

  • Gas and oil hydronic systems;
  • HVAC efficiency analyst
  • Ground source heat pump loop installation;
  • Air distribution.

NATE certification tells employers that you have mastered the knowledge and skills necessary to get the job done correctly the first time. Some employers require the appropriate NATE certifications before hiring or advancing an employee.

Best Options in the Field of HVAC

The BLS reports that more than 294,000 people work in the HVAC industry. Also, the field offers a variety of career options. Yet, installing and repairing residential and commercial HVAC-R equipment is the largest segment.

  • HVAC-R mechanics and installers: 212,810;
  • HVAC direct sales: 9,410;
  • HVAC wholesale sales: 8,070;
  • Commercial & industrial HVAC service: 6,170;
  • Educational facilities: 5,620.

These HVAC occupations account for 78% of all jobs in the industry. The statistics don’t include self-employed HVAC contractors such as the owners of local HVAC companies that employ most of the 294,000 workers in the industry. Most of those owners began their careers as HVAC technicians and later started their businesses. That’s an attractive career path for those with practical experience as an HVAC technician who have also obtained a business education.

A small percentage of the HVAC careers are in aerospace manufacturing, telecommunications, natural gas distribution and a wide range of related jobs.

To the Point

If this information has raised your interest in HVAC training, search online for training schools or call your local community college to find out what training programs are available near you.

Your friends and followers on social media might appreciate the information too as they consider their career. So, please pass it along if it has been helpful to you!

The Average HVAC Technician Salary On the Rise

Workers specialized in the science of heating, refrigeration, and air-conditioning do not usually receive the recognition they deserve. The newer generations perceive management and services instead as career fields worth their time and effort. The pressure to get a college degree is passed on to the young, along with the stigma of becoming a blue-collar worker. For example, many believe hands-on labor brings little in terms of financial gain. Yet, the average HVAC technician salary hits a high note on the skilled labor pay scale.

And not undeservedly. First of all, it takes training and certification to become an accredited HVAC technician. Secondly, working in the field can be more than uncomfortable – try replacing the desk and swivel chair with Spartan-like conditions in cramped spaces and either freezing or boiling temperatures. Incidents like electric shocks, burns or muscle strain are all in a day’s work.

how to earn an HVAC technician salary

No pain, no gain’ applies just as well to the profile of an HVAC technician. We’re all too eager to call one in times of need. Yet, we haven’t the slightest idea of what the job title entails. The demand for such skilled labor is certainly on the rise across the country. The industry is promoting new technologies every day. That means the HVAC technician has to keep up with the training and required certifications if he/she wants to stay competitive.

In the following article, we’re going to peer into the everyday life of an HVAC technician. The requirements for the job, the perks and lows of blue collar employment.

Is the Average HVAC Technician Salary Worth Working Up a Sweat?

Becoming an HVAC Technician– An All-Season Career

When did the need for an air-conditioning repair man come into being? Most likely, the answer will take us back in time to the first installation of a residential AC in 1931.

The first design to sit on a window ledge has been a trademark for the air cooling device ever since. The demand steadily grew, if only among the well-heeled at first. At the time, one unit would carry a price tag of up to $50,000, the equivalent of $600,000 today.

Once ‘coolth’ – the artificially cooled air – became a commodity, Americans found it less painful and horribly sweaty to live in the gulfs and swamps of the Southern parts. Every heat-sodden season brings a new increase in the demand for professionals who can install, maintain and repair those miraculous devices blasting invigorating cold.

An HVAC technician’s knowledge extends to more than fixing your home AC. If you’re behind your acronyms, know that HVAC is an abbreviation for heating, ventilation, and air conditioning. Someone who writes down this skill in his CV knows how to control the temperature, humidity, and total air quality in a building. Short of endowing him or her with god-like omniscience, we do need to recognize our dependency on an HVAC technician in terms of comfort and even wellbeing.

Many such skilled workers will specialize in either installation or troubleshooting a heating or cooling system. However, their training will comprise both. If you’re a high school student and about to embark on this path, you must be interested in tinkering with electrical equipment. More often than not, curiosities gravitate around mechanical drawing, electronics, applied physics and chemistry, and blueprint reading.

Educational Requirements

According to new statistics released by the Bureau of Labor Statistics, a nationwide shortage of HVAC technicians has recently coupled with a rise in the industry jobs, leading to a predicted growth of 14% from 2014 to 2024. Fortunately, the numbers fare well for those young people enthused about fixing, troubleshooting and installing.

To meet this demand that seems to have sky-rocketed much faster than the average for all occupations, 115,000 new skilled professionals will be put on the payroll in the next ten years. The same report from BLS stresses that those applicants who have completed postsecondary education or a professional three-year apprenticeship have better odds at finding a job. Employers prefer laborers who invest in formal HVAC training, even if in the form of classroom instructions. The latter can take place at a trade or technical school, or within the US Armed Forces.

Anyone with a blueprint on earning a steady and decent HVAC technician salary should read further on. Below is a brief synopsis of HVAC certification, a requirement of the U.S Environmental Protection Agency, or EPA, for anyone tinkering with electrical equipment that releases chemicals to the atmosphere.

Training – No Sweat, No Gain

Many people wrongly believe that an HVAC technician only receives nominal training or, worse yet, plays with hazardous equipment by the ear. Even before the first exams roll in and the pressure of acquiring the proper state certification hits home, a wannabe HVAC professional undergoes lengthy training of anywhere between 6 and 24 months at a technical school.

Apprenticeship to earn an HVAC technician salary

The classes range from electrical and gas systems to troubleshooting a heating system and communicant practices. At the completion of the course, the applicant will most likely achieve an associate’s degree.

Apprenticeships are also on offer, but span to around 5 years and earn the apprentice on-the-job training under the supervision of an experienced journeyperson. An aspiring residential HVAC technician can contact the local union or a community college to enroll for an apprenticeship.

Three Must-Have Certification to Obtain that High-Paid HVAC Technician Salary

Taking an exam to become an HVAC tech

Sweat Out the Exams

The NATE, or North American Technician Excellence certification is the most prestigious on the market and a golden ticket for HVAC technicians who want to push through the ranks to higher paid employment. Although it’s not legally required, the certification will surely prove a deciding factor when facing a job prospect.

In order to obtain the NATE certification, you have to prove your book smarts. You will be handed a knowledge-based exam that tackles heavy scenarios and tricky problems. In the end, the reward will be commensurate with the effort you’ve invested. Your standard HVAC technician salary should increase, along with the lists of clients.

The second HVAC Excellence certification comes as the result of the ‘Professional Level’ exam. To earn it, you have to bring two years of field experience and a decent exam score on the table. The test will be comprised of questions regarding residential heat pump and ventilation services.

The Master Specialist Level in HVAC Excellence Certification is the equivalent of a proficiency language test. This type of certification represents the pinnacle of an HVAC technician career. To obtain it, you need to make proof of three years of field experience plus a Professional Level Certification.


The EPA Section 608 Certification

The Environmental Protection Agency requires HVAC technicians working with equipment and containers that use refrigerant as a hazardous compound to obtain a special certification.

how to earn an HVAC technician salary fixing ACs

The EPA Section 608 consists of four different types or levels, each of which pertains to the various equipment the technician will have to maintain, repair or dispose of. Before your head starts swarming with all the accreditation needed in order to earn that daily HVAC technician salary, you should know that you are not required to pass all the four exams. Depending on the duties at hand or the job you wish to pursue, you can obtain only the certificate of interest.

  1. Type I Certification – Specific for the service of small appliances such as domestic refrigerators, window air conditioners, and vending machines.
  2. Type II Certification – HVAC technicians whose main job is to install, repair, and dispose of appliances containing high-pressure refrigerant such as process refrigeration, residential air conditioners, and heat pumps need to acquire this type of certification.
  3. Type III Certification – This third type is required of HVAC technicians who install and service equipment with low-pressure refrigerant, such as chillers and other industrial appliances.
  4. Universal Certification – The fourth type is the most complex and difficult to attain. As the name goes, it requires the professional to have the ability to install, repair, and dispose of all types of equipment, independent of the refrigerant type.

In order to pass any of the EPA exams above, you need to achieve a score of at least 72%.


State Licensing for HVAC Technicians

Some states require a license from the HVAC technician. If you move to another state, it’s important to contact the local professional licensing department and inquire about the proceedings of getting the proper certification.
Which begs the question. Which regions or states does the median HVAC technician salary score highest?

What’s Cooler Than Being Cool? Ice Cold Cash!

As mentioned before, as HVAC employers are experiencing difficulties filling job openings and the market is dealing with a talent shortage, the prospect of a higher paid HVAC technician salary is increasing exponentially.

HVAC technicians working

According to the aforementioned 2015 report, the U.S. Bureau of Labor Statistics indicated a median HVAC technician salary of $21.69 per hour. In other words, $45,110 per year.

While an entry level professional can expect to earn $27,210 a year, or $13.08 an hour, a master HVAC technician can earn a decent living wage of $62,210 per year, or $29,91 per hour.

Geography plays a role in the income variations as well. Depending on the demand and local living costs, wages are higher in some states than others. Alaska ranks first as the highest-paying state, averaging $62,210 per year. The District of Columbia and New Jersey follow close suit as the golden rush states for aspiring HVAC technicians. Surprisingly enough, Arkansas and Alabama rank the lowest with less than $30,000 per year.

All in all, you have the potential to make a great salary as an HVAC technician. Plus, the job outlook for the next ten years only displays positive signs of expansive growth and high demand. Consequently, the poorly paid and overworked blue-collar worker – at least in the HVACR field – is a busted myth. We wonder, are there any other misconceptions and prejudices to address?


Busting Some HVAC Myths

  1. ​To be an HVAC technician you need to belong to a union. The statement couldn’t be farther from the truth. According to a BLS report, only 1 out of 6 professionals are in one and there is absolutely no requirement to get a union job.
  2. HVAC is an unstable work field. As mentioned above, the demand for HVAC techs is only growing and, seeing how global warmth and the greenhouse effects follow suit, we can only expect an increase in improved ventilation and air conditioning technology -with the appending specialists to install and maintain it.
  3. HVAC play it by the ear. HVAC technicians are skilled workers with just as many diplomas and certifications to back their knowledge as in any other profession. It’s not easy to become an accredited HVAC professional. You need to be competent in mechanics, proficient with the inner working of electricity, an accomplished troubleshooter, and a decoder of complex blueprints. We won’t even mention all those EPA exams and state licenses that await an apprentice HVAC tech.
  4. There’s no room for women as well in the HVAC field. HVAC is a unisex profession, and women have been on the rise as HVAC techs in the last five years.​

Bottom Line

If you’re an aspiring HVAC technician in this day and age, you shouldn’t worry too much about unemployment or low job prospects. The average HVAC technician salary is only the rise, and all the better if you’re not tied to one location and can shift your geographical coordinates around. For example, how does Alaska sound to you?

How to Clean a Humidifier – 4 Steps to Keep Your Air Fresh

Our body is so addictive to water, we need it in the air as well, in the form of moisture. If you’ve ever lived in a dry climate, then you’ve experienced at least some of the symptoms – cracked lips that are constantly yearning for that glass of water, dry sinuses, throat that feels like sandpaper, nose bleeding, and an obnoxiously clingy cough that won’t go away. As luck would have it, the solution is at hand with the humidifier. Unfortunately, we tend to disregard that owner’s manual that comes with the tech package and, in no unclear terms states, why and how to clean a humidifier.

how to clean a humidifier

728x90 Get $50 Off Every Home Warranty

However, seeing how many of us tend to leave the good advice to the cobwebs and wave a hand in disregard to details such as ‘cleaning your humidifier’, chances are we’ll soon have to fight health issues that are sourced in the damp, moldy environment.

After all, it makes sense. Humidifiers use tap water, so they’re prone to bacteria and minerals depositing over time. When released into the air in the form of vapors, you breathe them in. To give you a comparison taste, imagine you’re brewing your morning coffee and, at some point while sipping the hot beverage, you remember the water in the coffee machine was several months old. Pretty gross, right?

Before we hand you the valuable tips on how to clean a humidifier and properly degunk it, we’ll have to clear the air of all the misconceptions. For example, how many scrubbing sessions do these devices need? And what are the best tools to reach those murky nooks and crannies?

How to Clean a Humidifier for Fresh Air

Tools for Scrubbing

You may be using the right products – we’ll obligingly list them all down the page – but, depending on the design of your humidifier, you may want to invest more attention in what tools you’re planning to use. It’s usually the corners and tight fits where mold tends to congregate.

  • Use a bottle brush to dislodge any pest buildup.
  • Q-Tips are like fluffy tiny scavengers. They can penetrate any dark and moldy corners.
  • Rags, sponges, old toothbrushes, or dishcloths.
  • Also, if you’re using bleach as an ingredient, protect your skin by wearing the classic yellow cleaning gloves.

How to Clean a Humidifier in Time?

Thoroughly cleaning your humidifier too often might turn out to be a drag. Manufacturers come with different recommendations. It really depends on the season. Seeing that the device is running to full blast during winter, you will want to invest more effort into maintenance than usual. Once the season is over and before storage, give it one final swish and shake.

Also, keep in mind that if you’re prone to allergies to mold and dust mites, you shouldn’t heavy-use the humidifier, as an increased humidity levels indoors nourish the two things.

Top Products to Clean the Humidifier

how to clean a humidifier with vinegar

Usually, manufacturers recommend that you clean your device with either our old pal white vinegar or bleach. Alternatively, you can also choose a few drops of tea tree oil in case the vinegar smell is overpowering. Also, dish wash works for a quick refreshing.

As the champion household cleaner, hydrogen peroxide is also an option on how to clean a humidifier. Its antifungal, antibacterial, anti-mildew, and anti-mold properties can really sanitize anything in your home. Just splash 3% hydrogen peroxide in your humidifier’s tank and filter and let it soak for more than 30 minutes. As opposed to the bleach and vinegar, this substance takes a while to harness its cleaning power.

How to Clean a Humidifier in 4 Steps

Washing

Step 1 – Break it Down

It might seem a bit pointless to mention this in the first place but, for extra security measures, we will anyhow. First step on how to clean a humidifier- turn off the humidifier and unplug it from the electrical outlet. Now would be the time to dust off that owner’s manual and do a bit of light reading. It will instruct you on how to take the humidifier apart.

As a rule, you usually start with the tank after you’ve poured all the water out. Then follows the filter, and if the model is such, the motor. Most humidifiers feature a catch which, in case you’ve lost your guiding manual, will be your clue to how many more detachable pieces are left.

Wash the filter and place it on a towel for any excess water drip off.

Disinfecting

Step 2 – Tank Up on Vinegar

The following step may require a small input of muscle power, because your humidifier’s tank really needs a good sweep. Here you have a number of options.

  1. Combine one cup of that glorified vinegar with one cup of tepid water. Pour the mix into an empty spray bottle, and aim and shoot at all those moldy corners of your tank. Allow one minute for the vinegar to dissolve the mineral deposits inside, then scrub away using a toothbrush or a sponge. Rinse off and then let the tank dry and shine with cleanliness.
  2. Fill the tank with water. Pour a generous teaspoon of bleach inside and let it sit for 20 minutes. Every two or three minutes, swish the mix around the container to ensure it thoroughly penetrates all those hidden corners. Follow up by giving it a thorough rinsing. Place it on a cloth to dry.
  3. If you’re apprehensive about both the vinegar and the bleach, use 3% hydrogen peroxide Pour a few cups into the water tank, swish it around to coat it evenly and let it sit for approximately an hour. Then rinse thoroughly.

TIP: Your home might stink of vinegar once you’re reusing the humidifier. Using a few drops of tea tree oil while in the cleaning process might cut some of the edge off that powerful smell.

TIP: Don’t run an errand while cleaning your humidifier with bleach, or you might end up with a broken machine. Let it sit for less than an hour.

Step 3 – Clean the Filter and the Base

In short, this step involves repeating the previous one, only, this time, you’ll be disinfecting any remaining detachable part of your humidifier. As we mentioned before, you can use vinegar, tea tree oil, bleach, or dish soap. The choice is yours.

Fill the base and filter with the solutions and let sit from 20 to 40 minutes. This timing can be pretty flexible, as long as you’re allowing the disinfecting substances enough time to clear the gunk.

Once again, arm yourself with a sponge, washcloth, rag, or anything with scrubbing power – cats may be furry, bristle and flexible, but they won’t do this time – and remove any remaining mineral residue.

TIP: For those bits of filth stubbornly lurking around in the crevices, use the Q-Tips or the bottle brush we’ve recommended.

TIP 2: If most of the dirt doesn’t slide right off after soaking, then you’ll need to prepare another vinegar or bleach bath for your humidifier. Clearly, you’re dealing with the kind of survivor mold that’s seen it all and still lived to tell the tale and damp the air. To be doing its job of tear and wear, the vinegar should be noisily fizzing.

Preventing Bacterial Growth

Step 4 – Keep a Proper Maintenance of Your Humidifier

Now all the parts are spick and span. Before proceeding to reassembly, make sure each piece is fully dried and that the vinegar smell dissipated. Preventing further bacterial growth doesn’t mean you will never have to go through the previous cleaning and disinfecting steps again! How to clean a humidifier? Repeatedly and thoroughly. 

You will, only that with proper maintenance and a good deal of care, the humidifier won’t be overloaded with mineral deposits and mold, and your arms won’t hurt from all that super-power scrubbing.

  1. Change the tap water often so that mineral deposits won’t have the time to coat your tank and filter.
  2. Clean the humidifier on a regular basis. Granted, you can’t invest all your time into obsessively taking care of your moist air supply. But no one is asking you to. However, a swift vinegar rinsing every three or four days won’t take more than 5 minutes of your schedule. The cumbersome disassembling and scrubbing process should happen every two weeks.
  3. If you’re the type to become attached to your trusted possessions, maybe an old, rusty humidifier is not the healthiest object to serve your nostalgic inclinations. Old devices break over time, but a worn out humidifier is fertile ground for bacteria, mold, and a charged air.

Ideally, indoor humidity levels for health and comfort as measured by the home hygrometer range between 40 and 50 percent. In winter times, when the heaters are working full blast, the moisture in the air can drop to just 15 percent. Compare it to the aridest desert in the world where the typical humidity is 10 percent higher, and you’ll understand the value of a humidifier. However, unless you follow our recommendations on how to clean a humidifier, breathing in air might turn detrimental to your health in the long term.

10 Humidifier Benefits

Humidifier benefits and plenty and many, some which you may have not even thought about. How can something as simple as a humidifier improve your health and your lifestyle? That’s a good question and we became determined to answer it.

Humidity is not something that you’d typically want to associate yourself with. Or, rather, it’s difficult to believe that anyone would willingly go out of their way to add some extra moisture to the air. After all, isn’t that something that people so commonly complain about during the insufferable, extra-humid summers? Precisely. For this reason, humidifiers aren’t exactly made for summertime use, but rather for winter.

During the cold season, temperatures drop, everything gets cold and harsh, and the air becomes dry. This is when a humidifier needs to step in. Of course, don’t imagine that owning a humidifier is equivalent to turning your house into a proper swamp. The effects are there, but subtle enough to not bother you and impactful enough to give you humidifier benefits.

What Does a Humidifier Do?

It’s not rocket science to understand the function of a humidifier. It’s a device that propels water vapors into the air, adding some light humidity around you. When used properly and in normal dosages, humidifiers can help combat a great deal of ailments associated with cold weather. You can moisturize your skin, get rid of chapped lips, prevent nosebleeds, and much more. In fact, a humidifier can even make your nights better by helping tone down that roommate that snores a lot.

Types of Humidifiers

There are several types of humidifiers and whether they’re right for you depends on budget, preferences, or how much are you need to cover.

  • Central Humidifiers: They’re the most expensive, but also the most effective types of humidifiers. Being built directly into the air conditioning or heating system of your household, they can cover a lot of ground. They’re a great way of ensuring the humidity spreads through your entire home.
  • Evaporators: These humidifiers use moistened filters in order to propel the humidity into the air. The unit is a separate entity, powered by fans which give enough to expel the moisture throughout the room. Although they’re definitely more affordable, they don’t cover as much ground, making them ideal for single-room situations only.
  • Steam Vaporizers: Like the name suggests, these humidifiers use a steam-based system. They heat up water, cool it slightly, and then expel the humid vapors into the air as steam. They’re possibly the most budget-friendly types of humidifiers and they’re easy to carry around because of their portable nature. The biggest downside is that they can cause burns if not wielded carefully.
  • Impellers: Similarly to evaporators, they’re most suitable for single rooms since their range isn’t impressive. They function based on a rotating-disk system. Comparatively to steam vaporizers, they produce cool mists, which make them child-friendly and risk-free as far as burns are concerned.
  • Ultrasonic Humidifiers: They do sound very sci-fi –like, especially when you consider the fact that they’re powered by ultrasonic vibrations. Prices for a unit of this caliber vary depending on the desired size. Their biggest advantage is that they’re a two-in-one deal since they come equipped both with cool and warm vapor options.

Humidifier Benefits For You

We need what humidifiers have to give us, otherwise we wouldn’t have invented them in the first place. If you’re still on the edge about whether you’ll have one installed in your home or not, perhaps the multiple humidifier benefits will change your mind.

#1 Dry Skin Treatment

As previously mentioned, stable levels of humidity in the air can help you with dry skin issues and with chapped lips. During wintertime, the combination of indoor heating methods and the naturally abrasive and rough cold air can leave its toll on your skin. Every time you turn on your indoor heating, you contribute to the replenishment of these already low levels of air moisture.

When the moisture in the air drops, so does the one in your skin, which turns dry and rough. Instead of investing in numerous skin treatments, the simplest way to solve is issue is with humidifiers. Install one in every room and watch the humidifier benefits improve the look and feel of your skin.

#2 Help For Your Nose

It might be a bit odd to read this, but bear with us. Humidity has a significant impact on the hairs and mucus of your nose. If the air is dry, you may notice certain impediments in normal breathing. Some people also experience nose bleeds, which are far from being uncommon during wintertime.

Adding some extra moisture to the air is going to help the tiny hairs in your nostrils to move normally and do their job. What job? It’s all going to be explained in the next step. The main point is: there is a reason why water vapor treatments are very often used for sinus issues. You’ll breathe better, bleed less frequently, and…

#3 Fight Against Colds And Flus

The purpose of nose hairs is to help filter out germs and bacteria that are responsible for the installment of common cold season illnesses, such as colds and flus. Without proper moisture, they can’t do their “job” properly and more often than not, the bacteria slips through and ends up giving us headaches (literally).

Alternatively, if it seems like it’s a little too late and you’re already down with a flu, it’s actually not. Humidifier benefits don’t involve only prevention, but also treatments. The stabilized levels of humidity in the air can help with a cold by soothing irritated nasal passages or with breathing issues.

#4 Asthma Relieving

Both children and adults can ease their asthma symptoms curtsy of humidifier benefits. Especially in the case of people suffering from a respiratory infection, using a humidifier can greatly soothe some of the asthmatic means of manifestation.

However, for asthmatics, humidifiers are more or less blades with two edges. You should always consult a doctor to ensure that it’s okay to install a humidifier. Moreover, you will need to constantly clean it and make sure to keep the humidity beyond a certain level.

#5 Furnishing Preservation

Wood Furniture

Wood furniture always has to suffer when too much or too little humidity is involved. Repeated exposure to dry air can cause the wood in some pieces of furniture to crack or form splinters. If you wish to preserve the health of your wood furnishing, consider installing humidifiers in any rooms that foster some pieces.

However, too much humidity can also harm them, so make sure not to turn it up too hastily.

#6 Happy Houseplants

Your houseplants give a lot, so we need to make sure that they receive in return too. During wintertime, they can suffer because of the dry and cold air. Perform a quick check-up on them. Is the soil drier than usual? Do the leaves look shineless and droopy? Then they’re definitely affected by the negative aftereffects of wintertime weather.

Keep a humidifier in the rooms that store your houseplants to give them a healthy dose of humidifier benefits. That doesn’t mean you can skip all the normal plant-care routines, so don’t forget to water them!

#7 Sound Chipper

Do you sound like Batman in the mornings? We all have that morning voice thing going on, but you can actually prevent it. Sleeping with a humidifier in the room is going to keep your vocal chords well-lubricated and healthy.

This is particularly important for all the singers out there. If you want to keep your singing voice crystal clear and always ready, it’s important to “feed it” the perfect dose of moisture.

#8 Warmer Environments

There is a reason why humidity and scorching summertime temperatures are such a deadly combo. The more humidity there is in the air, the warmer it will be. In other words, adding humidifiers during wintertime is also going to make your home feel generally warmer.

Comparatively, air that presents a temperature of 70 degrees Fahrenheit with 10% humidity will feel like 65 degrees. But the same 70 degrees will feel like 69 degrees when combined with 50% humidity instead.

#9 Static Electricity Control

Do you know that feeling when you’re taking off that wool sweater and it suddenly feels like you’re pinched from every side by tiny fireworks? Or how about that feeling when your hair gets glued to it? If you’ve ever had the misfortune of experiencing the pinch of static electricity, you’ll be relieved to know you can control it by making use of humidifier benefits.

#10 Better Sleep

And, yes, you can finally tone down the snoring of your roommate or significant other. Snoring is boosted by dry environments as a dry throat or sinuses can incapacitate our normal breathing.

Some Final Words of Caution

Humidifier benefits definitely outweigh humidifier negatives, but that doesn’t dismiss the fact that we do need to be careful to not accidentally make humidifiers our enemies. Moisture encourages the development of various organisms, such as mold or various types of dust mites and mildew. Keep things under control with balanced humidity levels and by constantly cleaning and changing the filters of your humidifier.
