All You Need to Know about Current Home Energy Efficiency Standards

Living with Home Energy Efficiency

Home energy efficiency is essential in today’s eco-conscious world and there is little inside a residential property that does not come into play, toward creating more energy efficient homes. From light bulbs to water heaters, from home appliances to the way a home is insulated, energy savings always start in the home and they always lie in the details. According to the U.S. Department of Energy, a home uses 42 per cent of its total energy expenditure on space heating, 18 per cent on water heating, 6 per cent for cooling the home, 5 per cent for lighting and refrigeration (each), while the remaining 24 per cent is spent on other uses. This is why regular home energy audits are important and why they can dramatically improve any home’s energy savings standing.

What makes a home energy efficient?

According to the generally accepted energy efficiency definition, a home is efficient in terms of energy expenditure, when its occupants actively manage and maintain energy consumption levels. The more energy efficient a residence, the more performance and services it manages to deliver, for the less energy consumption. The Office of Energy Efficiency & Renewable Energy (EERE) with the U.S. Department of Energy designs, improves, and enforces energy-efficient standards and technologies in several aspects that relate to home building and ownership.

  • Current Home Energy Efficiency StandardsHome building efficiency.  The EERE runs several research and development plans, as well as a host of market stimulation plans, such as Building America and the ENERGY STAR approach to building homes as a whole. It also awards homes an energy score, which gauges their overall energetic performance, encourages students to develop energy efficiency programs and designs, and enforces residential energy building codes.
  • Lighting standards. The Office is currently working to promote LED lighting better and to make sure the facts circulated about this technology are accurate. At the same time, it is encouraging the use of SSL (solid state lighting), which may one day cut down nationwide energy consumption levels to half their current values.
  • Equipment and appliance standards. The Building Technologies Office of the EERE is already enforcing energy savings standards for some 50 discrete categories of equipment and appliances. Thus far, this has resulted in saving some $55 billion on power bills in 2014 alone. The office projects that the amount of money saved from 1987, when the standards first came into effect, until 2030, will surpass $1.7 trillion.

What is energy conservation?

Energy conservation is closely tied in with energy efficiency. It is a concept that stems from physics, as the energy conservation definition illustrates. In terms of the home use of energy, conservation refers to cutting down on the amount of power used, by saving energy, reducing waste, and making sure the energy available is used rationally.

Nowadays, with several programs across the country aimed at improving energy consumption levels in the residential segment, it’s actually not that difficult to create a tailored energy conservation plan for your own home. For instance, best practice recommendations from the University of Colorado state that an occupied house can reach its maximum energy efficiency when its thermostat is set at 68 degrees Fahrenheit. The same recommendations advise against installing a central A/C system, save for the situation in which the whole house requires cooling down. Other tips include recycling old appliances and having them replaced with newer ones, which observe ENERGY STAR standards. Finally, if you’re thinking of building yourself a home, or of purchasing a new residential construction, you shouldn’t underestimate the potential of sun-tempered homes. By using passive solar energy, a super-insulated home of this type stands to cut down your energy consumption levels by up to 40 per cent.

Here are some other useful tips for homeowners interested in devising a customized energy conservation plan:

  • Thermostats should be set back during the night (by some 8 F) or when the house is not occupied for 24 hours (down to 50-55 F);
  • Unused rooms can be heat-sealed by keeping their doors, windows, and heat registers closed.
  • Heating systems need to be regularly cleaned, with filters replaced about once a month during the months when heating systems are in use.
  • Hot water leaks and other losses can also render a home less energy efficient. As such, owners should make sure none of their faucets are leaking and have low-pressure shower heads installed. Make sure the water temperature on your washing machine is set to an appropriate level and invest in an ENERGY STAR water heater.
  • Refrigerators should be set to 35-40F, with freezers at 0-5F. Don’t hold fridge doors open for too long and keep ice buildup levels in the freezer down to an absolute minimum.
  • Reduce the intensity of any gas cooker to the point where the flames are blue instead of yellow.
  • Only run the dishwasher when it’s full and let them air dry in there. Newer models no longer require that you rinse the dishes before washing them.

Goodman Furnace Review: Pros, Cons, Performance, Top Picks

This Goodman furnace guide details your Goodman furnace options, their technical and performance specs and the pros and cons of choosing Goodman. This brand is the low-cost leader, but there are ongoing concerns about Goodman quality.

Goodman is an American success story with a Japanese ending. Harold Goodman’s company made flexible ductwork until 1982 when he bought HVAC brand Janitrol and started manufacturing Goodman furnaces, air conditioners and heat pumps. Goodman aggressively carved out a niche as the leading low-cost brand. After Harold Goodman’s death, the brand was sold several times. Goodman Global, with US headquarters in Houston, TX, is now part of Daikin Industries of Osaka Japan after a $3.7 billion purchase in 2012.

Goodman Furnace Brand Overview

Like all leading HVAC brands, Goodman manufactures 80% efficient furnaces and 90%-plus furnaces. The 80% AFUE furnaces are offered in two performance levels, those with single-stage gas valves and two-stage gas valve furnaces.

The 90%-plus furnaces range in efficiency from 92% to 98%. In addition to single-stage and two-stage models, the GMVM97 Goodman furnace has a modulating gas valve that adjusts in 1% increments.

Goodman Furnace Technical Specifications

  • Goodman 80% furnaces lose 20% of the heat they create through the exhaust, so must be vented through the roof. Most of the 90%-plus furnaces have a secondary heat exchanger to capture additional heat from the exhaust. These furnaces can be vented through a wall.
  • Single-stage Goodman furnaces run at full capacity whenever on. They are inexpensive, a bit noisy and cause minor temperature fluctuations. The top 80% single-stage furnace is the GMS8 with multi-speed blower; the best 90%-plus single-stage furnace is the 96% efficient GMEC with multi-speed ECM blower.
  • Two-stage Goodman furnaces run at 65% capacity to keep temperatures more steady, and they switch to 100% capacity when a significant boost in temperature is required. The top 80% two-stage models are the GMVC8 and GCVC8 with variable-speed blowers; the best 90%-plus two-stage Goodman furnaces are the GMVC96 (Upflow/horizontal) and GCVC96 (Downflow/horizontal)
  • The modulating Goodman furnace has a gas valve that opens from 40% to 100%, running at the lowest (and quietest, therefore) capacity necessary to maintain the temperature of the thermostat set point. The only modulating Goodman furnace available is the 98% AFUE GMVM97.
  • Two blower options are available, multi-speed (good) and variable-speed (better). The noise level of the furnace and its ability to produce balanced, comfortable temperatures improves at each performance level, but so does furnace cost.
  • Upflow/horizontal and downflow/horizontal furnaces are made across the Goodman furnace range.
  • Each Goodman furnace is made in capacities from about 40,000 BTU to 140,000 BTU to fit the space to be heated.

Pros and Cons of Goodman Furnaces

Here are the reasons Goodman is the leading low-cost brand and a few cautions to consider before buying one. For comparison, see our guide to Trane furnaces, a leader among premium furnace brands, and guide to Rheem furnaces, a moderately-priced brand.

Goodman Furnace Pros

  • Goodman’s selling point is that it offers decent quality at a low price, so its furnaces are among the best values on the market;
  • Warranties for Goodman furnaces are among the very best in the industry, better than Trane, Carrier, Bryant, American Standard, Lennox, Rheem, Ruud and most others;
  • With 80% to 98% efficient furnaces at several performance levels, you’ve got excellent options to suit your budget, heating needs and climate control preferences;
  • The aluminized steel heat primary and stainless steel secondary heat exchangers are durable;
  • Goodman is a nationwide brand, so finding an installer will be easy, and the brand can be maintained and repaired by any certified HVAC technician;
  • The most efficient models can be direct-vented out a wall rather than the roof, so this reduces installation costs;
  • Many of the Energy Star furnaces from Goodman qualify for rebates from energy companies around the United States;
  • Goodman makes air conditioners, thermostats/controls and indoor air quality units to complement its furnaces in a complete HVAC system;
  • Goodman furnace thermostats include value-priced models, mid-priced controls and high-end touchscreen thermostats with Wi-Fi connectedness that allows you to control your HVAC system using a smartphone and free app.

Goodman Furnace Cons

  • The major advantage of Goodman – decent equipment at value pricing – is also its major flaw; Goodman furnaces currently don’t demonstrate the quality of those from brands like Trane, Lennox, Carrier or Heil, though this might change under Daikin control of the brand;
  • With quality concerns, a Goodman furnace is a cheap, short-term (up to 12 years) option, but for long-term durability, it makes sense to consider one of the premium brands;
  • Similarly, savvy homebuyers who see a Goodman furnace might have concerns that affect their buying decision;
  • While warranty coverage is excellent, the limited lifetime warranty won’t transfer to a new owner if you sell your home.

Things to Consider Before Purchasing a Goodman Furnace

In terms of the brand, you’ve got to decide if you want a cheaper, less expensive Goodman furnace that might need to be replaced in 10-15 years or a furnace from a brand known for durability. While Goodman’s warranties on the equipment are excellent, most don’t cover labor costs beyond one year (the industry standard). This means that you still might get stuck with a sizable bill if the furnace fails.

Keep your climate in mind. An 80% furnace is cheap, but will produce high heating costs in cold climates. On the other hand, in warm climates, the extra cost of a 90%-plus furnace might not be made back through lower energy costs for 10-20 years.

Make sure your contractor does a load test before choosing your furnace. This will ensure that the right size unit is installed. A furnace that is too large will create overheating issues in your home; one that is too small will struggle to keep up in the coldest weather and will likely have early mechanical issues.

Troubleshooting Furnaces: 8 Furnace Repair Parts You Might Need to Buy

Q: Why is my furnace not heating the house?

A: There can be any number of reasons why your furnace is not heating. We’ve collected the most common ones below, but be advised that testing some of these hypotheses will require the aid of a qualified professional, plus the purchase of furnace repair parts. The parts that might be causing you trouble have been listed in order of how commonly they occur, starting with the most troublesome ones. We’ve also added some less than ideal situations in which your furnace might break down to the point where it’s no longer heating your home.

Igniter

The igniter that’s supposed to light up the gas flame is not working properly. All furnace igniters have 120 volts running through them, provided by the main control board of the heating unit. When it does work, it’s lit up to the point where it starts glowing a bright hue of orange. A cracked or faulty igniter will need to be replaced.

Flame sensor

Furnace Repair Parts and Flame SensorThe flame sensor that’s in charge with monitoring the gas burner is failing to properly detect the flame. This, in turn, will cause the control board to stop supplying the gas valve with power, hence bringing ignition to a screeching halt. Try cleaning up the flame sensor with an abrasive material (nothing too harsh) before you consider replacing it. If the problem repeats itself, then you’re definitely going to have to buy a new flame sensor.

Draft induction motor

When it breaks down or malfunctions due to shoddy manufacturing, the draft induction motor of the furnace stops properly drawing air inside the burner unit. Under normal circumstances, the air brought inside the unit would then go out through the flue of the furnace. There’s also a pressure switch inside the burner unit, which this flow of air needs to close down, in order to indicate to the main control board that air is flowing through the heating system the way it’s supposed to. Without auctioning the switch, the ignition process will fail to start or be delayed.

Main furnace control board

Most problems that require furnace repair parts and professional assistance boil down to a single issue: ignition is not occurring the way it should be. If the control board of the furnace is at fault, then you’ll absolutely have to get a new one, since fixing them is a very complicated process. A control board that’s not working well will fail to power all the other components involved in the ignition process with the voltage they require.

Flame rollout switch

There are several switches inside a furnace heater and this one is in charge with making sure the heat around the burners is being properly regulated. Normally, the flames from the burner should be led into the heat exchanger and exhausted out through the flue. When the roll-out switch is malfunctioning, it will fail to properly acknowledge this process, open, and stop the heating process inside the furnace. This is most often caused by the fact that the furnace is placed in a room where there’s not enough air, or because one of its exhaust vents is jammed. Before splurging on furnace repair parts, always check out if your vents and registers aren’t being obstructed by rugs, furniture, or other items.

Thermostat

Make sure that all the contacts inside your wall thermostat are working properly. If they’re not, then there’s no way your furnace could heat your house the way you want it to.

Gas valve

During ignition, the main control board of the furnace sends 24 volts into the gas valve assembly. If that valve isn’t working well, then it won’t open the way it should, hence not allowing gas to flow inside the burners. First off, you will need to make sure the problem doesn’t lie with the control board, as outlined above. But if there’s proper power flowing through the valve, yet it still fails to open, then that’s your culprit right there.

Pressure switch

During draft induction, air flows through the furnace burner; at the end of this process, a pressure switched is flipped, indicating to the main control board that the air is flowing properly through the burner. Subsequently, ignition will be initiated and the furnace will heat up. If the pressure switch won’t close, then there’s no way the furnace can ignite the flame.

Troubleshooting situations unrelated to furnace repair parts

Aside from all the above scenarios, make sure the furnace is being properly supplied with all it needs in order to work well. Here are some of the most common supply-related situations that could be causing your furnace to malfunction:

  • Insufficient gas supply. Make sure the gas valve is turned on – if it is, then your gas company is to blame for this. Alternatively, if your furnace runs on propane, it’s time check the levels on that.
  • Insufficient air supply. Always check out the manufacturer’s recommendation on ventilation before you have a furnace installed. Some will simply ‘choke up’ due to a lack of sufficient air, when mounted inside a closet or other small, poorly ventilated space. Also, if your furnace draws air in from outdoors, make sure the inlet is not jammed by any foreign object.
  • Insufficient power supply. Always check out the circuit breaker or the fuse for your furnace in the proper fuse control panel if it seems like the furnace isn’t getting enough electricity.

Goodman AC Review: Pros, Cons, Performance, Top Picks

This Goodman AC guide provides performance and technical specifications for the five Goodman models, efficiency ratings and the pros and cons of choosing Goodman.

Goodman started making air conditioners in 1982. It quickly gained impressive market share with low prices and excellent warranties. On the other hand, there have always been concerns about Goodman quality, though it’s possible that will change following Daikin Industries’ purchase of Goodman’s purchase in 2012. For now, Goodman remains in the low-cost niche. Japanese company Daikin is the largest manufacturer in the world of HVAC equipment. Goodman is headquartered in Houston, TX and has four US manufacturing plants.

goodman air conditioning and heating

Goodman AC Brand Overview

The five Goodman AC models provide a limited range of efficiency, performance and price for consumers to consider.

Models GSX13, GSX14 and GSX16 are single-stage heat pumps. The number is the SEER rating, or seasonal energy efficiency ratio. The higher the number, the more efficiently the system uses refrigerant to capture heat inside your home and transfer it outside. The Goodman DSXC16 and DSXC18 are two-stage heat pumps. Goodman does not make a modulating heat pump, putting it behind brands like Trane (see our Trane AC review here), Lennox and Carrier.

Goodman AC Technical Specifications

  • The single-stage ACs cool at full capacity (and full noise) whenever running. Single-stage AC tends to cool past the thermostat set point creating mild temperature fluctuations you might notice. The GSX models use a universal scroll compressor of average quality, at best.
  • The top Goodman single-stage AC is the Goodman GSX16.
  • The two-stage Goodman AC models run at about 65% capacity (and noise level) most of the time to deliver gentler, more balanced air conditioning that won’t cool past the set point. They boost capacity to 100% only when you lower the thermostat setting or outside temperatures climb quickly and the AC needs to catch up.
  • Both the Goodman DSXC16 and DSXC18 use the highly regarded Copeland two-stage Ultratech scroll compressor. These are Goodman’s best overall ACs.
  • The “C” in the nomenclature of the DSXC16 and DSXC18 means the units are compatible with the Goodman ComfortNet Communications System, an upgrade (about $400) that optimizes efficiency and climate control.
  • Goodman AC units are available in capacities from 1.5 tons (18,000 BTU) to 5.0 tons (60,000 BTU), though half-ton increments are not offered in all model numbers.

Pros and Cons of Goodman Air Conditioners

Here are the advantages that make Goodman one of the best-selling AC brands along with a few disadvantages which might affect your purchase decision.

Goodman AC Pros

  • Goodman ACs are the value leaders in the market due to their reasonable quality and low prices;
  • Most Goodman AC models are backed by an outstanding warranty – Goodman as a brand has the best replacement warranties in the industry;
  • Goodman 16 SEER and 18 SEER ACs are Energy Star rated and might be eligible for energy company rebates where you live – check here for rebates;
  • Goodman central air conditioners use R-410A refrigerant which is believed to do less harm to the environment than older refrigerants;
  • Goodman still makes a 13 SEER AC, the least efficient allowed by law, which is a good choice where the air conditioning is needed infrequently;
  • Goodman is a national brand, so finding a dealer/installer is easy, and parts for maintenance and repair are readily available – at least in the continental US.

Goodman AC Cons

  • While making affordable ACs, Goodman’s long-term reliability record is not as good as other top-selling brands like Carrier, Lennox, Trane, Heil and Maytag;
  • While the parts warranties are excellent, labor is generally not covered beyond one year – the industry standard – so you might face expensive repair bills if your Goodman AC breaks down;
  • For those in extremely hot climates or who want the most ecofriendly cooling regardless of where they live, there are more efficient ACs available including the Lennox XC25;
  • (26 SEER), Maytag PSA4BI IQ Drive (25.5 SEER) and many from 19-24 SEER;
  • Goodman’s best ACs are two-stage models, and they don’t provide the level of indoor comfort, temperature balance and dehumidification for your home as modulating central air conditioners made by several leading brands provide;
  • Goodman air conditioners have historically been wholesaled to any HVAC installer, and you might get inferior installation if the company you choose isn’t factory-trained to install Goodman.

Things to Consider Before Purchasing a Goodman AC

The first issue to address is the historically inferior quality of Goodman to other top brands. Among HVAC experts, the consensus is that if you want a decent air conditioner with a 12 to 15-year lifespan, then Goodman offers good value. If you want a dependable, 20-year AC, look elsewhere. Keep in mind that this might change with Goodman in the future. Daikin also bought Amana and upgraded the quality of its entire lineup that had been identical to Goodman’s.

The next issue is your climate and use. Goodman AC models GSX13 and GSX14 are suited to cool climates or locations like vacation homes or guest apartments that don’t get heavy use. Despite paying progressively more for the GSX16, DSXC16 or DSXC18, the higher upfront cost will be paid back pretty quickly in very warm climates. If your summers are extreme, choose the 18 SEER Goodman AC or look at more efficient central air conditioners from other brands.

Conclusion

Do you know folks that might find this Goodman AC guide useful? If so, please pass it along to your friends and followers. They might also be considering a Goodman air conditioner for their home and will appreciate the information.

Freon Leak Detector: Pros and Cons

If you think you need a Freon leak detector, then you definitely need one since Freon leaks are a serious matter. Prolonged exposure to Freon can lead to fluid buildup in our lungs, 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 with as much as 35%. Here are the main types of Freon leak detectors and their advantages and disadvantages:

freon leak detector

Professional Freon Leak Detector:
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.

Now, here are the most common and the most efficient methods to detect Freon leaks:

Liquid Freon Leak Detectors

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

Pros of Liquid Freon Leak Detectors

  • Very cheap.
  • Easy to make and use.

Cons of Freon Leak Detectors

  • 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 don’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 Freon Leak 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 of an Infrared Freon Leak Detector

  • 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 of an Infrared Freon Leak Detector

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

Electronic Freon Leak Detector

There are 2 main 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 of Electronic Freon Leak Detectors

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

Cons of Electronic Freon Leak Detectors

  • 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 Freon Leak 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 of Dye Freon Leak Detectors

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

Cons of Dye Freon Leak Detectors

  • 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 Freon Leak 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 of the Halide Torch as a Freon Leak Detector

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

Cons of the Halide Torch as a Freon Leak Detector

  • 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 Freon Leak Detector

Ultrasonic leak 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 of an Ultrasonic Freon Leak Detector

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

Cons of an Ultrasonic Freon Leak Detector

  • 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.

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 refrigerant.
  • Keep in mind that air conditioners or heat pumps with fans will direct the air in a certain direction.

Also, 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.

Goodman Heat Pump Review: Pros, Cons, Performance, Top Picks

This Goodman heat pump guide provides information you can use to decide if a Goodman product is right for your home or business. You’ll find performance and technical specifications for the four Goodman heat pump units, top models and the pros and cons of choosing the Goodman brand.

Since Harold Goodman began manufacturing HVAC components in 1982, Goodman has captured huge market share by being the low-cost heating and cooling brand. Its quality has been suspect, though. Global HVAC giant Daikin has owned Goodman since 2012 and appears committed to keeping the brand in its traditional price-conscious niche.

goodman heat pumps

Goodman Heat Pump Brand Overview

Daikin has reduced the Goodman heat pump lineup to just four models. This provides consumers with a limited number of options for efficiency and performance. Compare that to the eight Trane models reviewed on our site or the 17 Carrier heat pumps. The GSZ14 (15 SEER/9.0 HSPF) and GSZ16 (16 SEER/9.0 HSPF) models are Goodman single-stage heat pumps.

The DSZC16 (16 SEER/9.5 HSPF) and DSZC18 (18 SEER/9.5 HSPF) heat pumps are two-stage Goodman heat pumps.

Note: The higher the cooling SEER (seasonal energy efficiency ratio) and heating HSPF (heat seasonal performance factor), the more efficiently the Goodman heat pump transfers heat out of or into your home.

Goodman Heat Pump Technical Specifications

  • Goodman single-stage heat pumps are the most affordable and least efficient. They run at 100% capacity when on, so they’re noisy and may heat and cool past the thermostat set point
  • The top single-stage Goodman heat pump is the Goodman SZ16 with built-in defrost function and high/low pressure switches
  • Goodman two-stage heat pumps cost more but deliver quieter, more comfortable climate control by running at 65% capacity most of the time unless you change the set point or the outdoor temperatures rise/fall quickly and the heat pump must catch up
  • The overall best Goodman heat pump is the two-stage DSZC18 with defrost, pressure switches and compatibility with Goodman’s ComfortNet Communication technology that optimizes climate control and efficiency
  • While the single-stage Goodman heat pump models are built with a compressor of standard quality, the two-stage models feature the well-regarded Copeland Ultratech scroll compressor made by parts giant Emerson
  • Goodman has its own short-cycle prevention technology called SmartShift that protects the compressor and improves longevity
  • Factory-installed filter driers remove moisture from the refrigerant before it can reduce effectiveness

Pros and Cons of Goodman Heat Pumps

Here are the main reasons consumers choose a Goodman heat pump or stay away from this brand.

Goodman Heat Pump Pros

  • Goodman combines good (though not outstanding) quality with some of the lowest prices in the industry to create excellent value;
  • The warranties on Goodman heat pumps are among the industry’s best including complete unit replacement for a failed compressor;
  • All Goodman heat pump models are Energy Star rated and the most efficient may qualify for significant rebates from your energy company – find out here;
  • Because Goodman is a nationwide brand, installers and repair parts are readily available;
  • Goodman heat pumps use R-410A that is shown to be less impactful on the environment than older residential HVAC refrigerants.

Goodman Heat Pump Cons

  • The primary concern about Goodman is the shaky dependability record beyond 10 years;
  • The reduction of the lineup to just four models gives consumers less options than are available with most other brands;
  • The most efficient Goodman heat pump, the DSZC18 (18 SEER/9.5 HSPF), has lower efficiency ratings than competitors such as the Lennox XP25(23.5 SEER / 10.2 HSPF), Trane XV20i (20 SEER /10 HSPF) and the Carrier Infinity 20 / Bryant Evolution 280A (20.5 SEER/13 HSPF);
  • While the Goodman heat pump parts warranties are outstanding, most don’t cover labor on repairs past the industry-standard 12 months, and this means you might have high repair bills if your Goodman unit fails prematurely;
  • Most other top brands have introduced a modulating/variable-capacity heat pump that delivers 20+ efficiency and tremendous climate control, so Goodman is a step behind;
  • Goodman heat pumps are sold to any HVAC company, not just those certified by Goodman, so make sure your installer has Goodman training and certification.

Things to Consider Before Purchasing a Goodman Heat Pump

When considering saving money on an affordable heat pump, you must take into account the mediocre service record of Goodman. The trade-off is lower price for a unit that should last 12-15 years but might have a few mechanical issues versus the higher cost of a premium heat pump that will last 20+ years.

Take your climate into consideration too. The more extreme your weather, the more efficient the unit should be. In very hot climates, only consider heat pumps with 20 SEER or higher, something Goodman doesn’t offer, though parent-company Daikin does in the Daikin D21 SEER/10 HSPF DZ20VC.

The more important precise indoor comfort it, including dehumidifying your home in hot summer weather, the more efficient the unit should be. Single-stage models do a poor job with climate control, and two-stage models are better. Modulating/variable-capacity heat pumps such as the Lennox XP25, Maytag iQ Drive PSH4BI and Carrier Infinity 20 are the best, but Goodman doesn’t make one.

Conclusion

We trust this information has helped you decide whether to consider Goodman heat pumps or to rule them out. If this information would be of interest or help to your friends and followers on social media, why not pass it along? Perhaps it will help them select a heat pump that saves them money and does a superior job making their home comfortable.

Three Best Home Air Purifier Reviews

Before we shop for a product, we shop for reviews. Reports from consumers and advice from specialists help clear the air when you’re in a fog about which features and functionalities you should look for. For example, you’re in the market for a home air purifier. You yearn for that crispy clean air that spreads like an invisible freshly laundered sheet over the room.

Given the potentially overwhelming number of things to consider, though, you’re a bit at a loss. What type of filter or air flow rate should the ideal air cleaning machine exhibit? How does it perform at high speeds comparative to low speeds? Is it stealthy quiet or loud enough to have your neighbors knocking on your doors?

Overselling can be an easy trap to fall into. We’ve filtered through a mass of ratings and accounts and dusted off any traces of biased or irrelevant claims. In the end, we came up with a few winners that will perform best for your needs and improve indoor air quality.

Home Air Purifier

In theory, a home air purifier should remove up to 99.9% of the smallest-sized pollutants and allergens, such as dust, pollen, mold mist, tobacco smoke, viruses, and bacteria. Most people purchase a product of the likes to ease asthma symptoms, alleviate allergies, or even treat contagious diseases such as flu. However, there’s little actual medical evidence that a home air purifier relieves respiratory problems.

So take a deep breath – if it doesn’t make you cough. But first, before we plunge you into the mystifying world of air cleaners, let’s try some of the more conventional and less expensive ways to purify the atmosphere in your home. What can you do to reduce the air pollutants from an enclosed living space?

  1. Prohibit smoking indoors.
  2. Vacuum often using a vacuum cleaner with HEPA filtration, a high-efficiency particulate air machine that traps air irritants in a mesh.
  3. Provide monthly maintenance for your heating and air-conditioning equipment. Change the filters regularly.
  4. Put the kitchen and bathroom exhaust fans to regular use.
  5. Store any chemicals, glues, or pesticides outside the living area.
  6. Candles and crackling wood fire tend are as romantic as they are harmful to the air quality around. Use as rarely as possible.

The Best Home Air Purifier for a Breath of Fresh Air

Things to Consider When Buying an Air Purifier

Following our next tips could simplify the purchase process and reduce the bewildering range of products on the market to a few cherry-picks to give you the sweet taste of a truly competent air purifier. Of course, personal preference will ultimately seal the deal.

Clean Air Delivery Rate

Home Air Purifier

CADR stands for Clean Air Delivery Rate and indicates the volume of filtered air delivered by a home air purifier. AHAM, the Association of Home Appliance Manufacturers, has been conducting tests and measuring the CADR of air cleaners for four decades now.

CADR also stands for an objective standard of the effectiveness of an air cleaning machine. Regardless of the technology in use – HEPA filtration or ionizer, for example, the CADR gives three separate readings of pollutants such as dust, pollen, and smoke.

For example, when it comes to the tobacco ratings, AHAM applies the ‘the two-thirds’ rule. ‘You’ll always want a unit with a tobacco smoke CADR at least 2/3 your room’s area.’

Look for higher ratings since they translate into the air purifier’s ability to filter a pollutant. Scores range from:

  • Tobacco Smoke: 10 to 450 CADR.
  • Dust: 10 to 400 CADR.
  • Pollen: 25 to 450 CADR.

Energy Saving Power and Lower Operating Costs

Home Air Purifier

Your average air purifier will use more than a refrigerator, approximately 550 kWh per year in electricity. If you aim at cutting costs, look for brands that bear the Energy Star seal. It means they are up to 40% more energy-efficient than the standard on the market, a feature that will cut in half your home’s electricity consumption and utility bills.

Maintenance expenses shouldn’t be overlooked either. In a single year, many portable air purifiers will bring the costs higher in replacement parts than their original purchase price. Pay particular attention to filters!

HEPA air purifiers use HEPA, or high-efficiency particulate air filters to remove over 99,97% of the airborne irritants in a size as tiny as 0.3microns. On the other hand, a non-HEPA air cleaning machine doesn’t do battle with more than 85% to 95% of air contaminants.

Filters carry price tags that run from as little as $10 to about $100. However, they don’t last long in the race against time. In many cases, you’ll find yourself with a broken filter every three to six months. One useful feature is a filter change indicator. It will let you know when to switch to another filter so you don’t buy one prematurely.

Another recommendation is to look for a home air purifier equipped with a pre-filter. The added feature offers a longer life span to your air purifier by trapping the larger pollutants before they reach the main filter. If the pre-filter itself is washable or can be vacuumed, you’ve really hit high-quality merchandise.

Are You a Fan of Speed?

Home Air Purifier

However, air flow depends on more than the type of filter in use. The speed of the fan is also worth considering when buying an air purifier. Most models include settings that allow you to control the fan at various air cleaning needs.

For example, choosing a higher speed makes sense if the air purifier’s sensors register an increased level or airborne harmful particles that need to be filtered faster. On the other hand, set your filter on lower gear at night time if the noise of pollutants being exterminated disturbs your peaceful sleep.

Enjoy the Silence – Noise Levels on the Shhh

Quietness counts, especially when we have ourselves surrounded with machines and devices that give out a permanent white noise, undercutting our need for precious silence. If you choose a larger unit and keep it on a lower speed, you won’t have to go to sleep wearing ear plugs.

The World Leaders Among Air Purifiers!

The top selling air purifiers are portables. They can be moved around in order to air out every other room in the house. Let’s see how the next brands fared in the battle against air irritants and pollutants.

1. Germ Guardian AC4825 Home Air Purifier Review

Home Air Purifier

If a brand’s reputation lies in the name, then you can hardly fail with a home air purifier called the Germ Guardian. The model uses a very handy 3-in-1 air cleaning system that is highly intolerant to dirty and smelly air. As it should be.

Its main draw is this superposition of filters:

  1. The pre-filter uses activated carbon to trap dust, lint, and hair.
  2. The HEPA filter deals with the mold spores and pet dander.
  3. The UV-C light layer eliminates any danger of rhinovirus, streptococcus, and E. colispreading through the room.

The unit’s CADR, or Clear Air Delivery Rate is 100+ which makes for an adequately high standard rating. Moreover, put the Germ Guardian AC4825 in any beauty competition and its sleek black silhouette and twinkling blue LED light will win it the big prize.

To welcome the Guardian into your home, take a look at Amazon and see if the very affordable price tag fits nicely with all the other competitive features.

2. IQAir New Edition HealthPro Plus Home Air Purifier Review

Home Air Purifier

Everyone seems to be panting for air to bring to your attention the IQAir New Edition HealthPro Plus air purifier. More so after Frank Hammes, the president of IQAir, apparently tested it himself by entering a chamber where a SEAL team shot poisonous gas through. If you want to be impressed, check it out yourself here.

This sterling model goes beyond absorbing air pollutants as small as 0.3microns with the HEPA filter. It boasts a microparticle retention rate up to 100 times higher than the regular filter. All in all, the IQAir home purifier perceives the Higgs-boson of air contaminants, which are known as VOC, or volatile organic compounds. Basically, these are petrochemical airborne particles that home appliances emit all around your house.

The HealthPro also dwarfs competition when it comes to noise levels. Its six different fan speeds ensure your home air purifier will be as silent as a ninja. You may wish to be the proud owner of a top-notch device such as this, but first, read the price tag on Amazon. Your newfound enthusiasm might end up disappearing into thin air.

3. Airocide APS 200 Home Air Purifier Review

Home Air Purifier

The Airocide really breaks the ranks of modern home air purifiers. Nothing less is to be expected from a piece of technology that NASA developed and implemented. The reason this machine stands out from the crowd is that it removes air pollutants not with the use of a filter – it’s actually filterless – but through the means of a highly reactive catalyst.

Who doesn’t want a piece of NASA’s ingeniousness in their home? The price sure beats the previous competitor on our list.

Are You Still Up in the Air About It?

Listen to the professionals. According to the Environmental Protection Agency, levels of about 12 VOC pollutants are up to five times higher indoors than outside. And the result comes regardless of whether the area is rural or highly industrialized. In this situation, a home air purifier can really make a difference for your lungs and overall health. Take that deep breath and feel inspired with wellbeing!

Trane Brand Overview

Trane has grown to be a global leader in residential and commercial HVAC systems, a steady climb from its launch by James Trane in Lacrosse, WI in 1885. Today, the Ingersoll-Rand Corporation owns Trane and nearly identical brand American Standard. The best Trane heat pumps are in the top ten in both customer satisfaction and cost. If you’re looking for a budget heat pump, see our Goodman Heat Pump Review for comparison.

Trane Heat Pump Technical Specifications

You’ve got options to fit your climate, budget and how you’ll use the heat pump. The term SEER (Seasonal Energy Efficiency Rating) refers to cooling while HSPF (Heating Seasonal Performance Factor) refers to heating. The higher the numbers, the more efficiently the unit uses electricity to heat and cool.

  • Single-stage heat pumps are the most basic and affordable, and they run at 100% capacity (and noise level) resulting in slight overheating and cooling that produces temperature fluctuations;
  • The most efficient single-stage Trane heat pump is the Trane XR16 with 17 SEER/9.6 HSPF ratings;
  • Two-stage models run at about 65% capacity (and noise) most of the time to produce quieter, more balanced temperatures, and they run at 100% capacity when you call for more heat/cooling at the thermostat or outside temperatures change quickly;
  • The best two-stage Trane heat pump is the Trane XL18i with 18 SEER/9.5 HSPF efficiency;
  • The two Trane heat pumps with variable-speed technology, called modulating and variable-capacity by other brands, adjust from about 40% to 100% capacity (and noise) and run at the lowest capacity required to optimize temperature balance and indoor comfort;
  • Trane’s most efficient heat pump is the variable-speed XV20i with 20 SEER/10 HSPF efficiency.

Pros and Cons of Trane Heat Pumps

Trane heat pumps offer the advantages and disadvantages listed here.

Trane Heat Pump Pros

  • Trane heat pumps are durable, and most will last 15-20+ years when properly maintained, and the Climatuff ® compressor used on all models is one of the most reliable in the industry;
  • Eight Trane models are offered at various price/efficiency levels to give you options to suit your heating, cooling and performance requirements;
  • Trane makes most heat pumps in capacities from 1.5 tons / 18,000 BTU to 5 ton tons / 60,000 BTU to provide a model properly sized to your home;
  • Trane Earthwise hybrid heat systems use both a heat pump and a gas furnace, an ideal combination for homes in very cold climates;
  • Trane Comfort-R technology does a superior job dehumidifying a home during air conditioner cycles;
  • Complete split systems and package units are made by Trane for coordinated heating and cooling, air quality control and HRV/ERV home ventilation;
  • Trane has a nationwide network of certified technicians for installation, maintenance and repair, and parts are readily available – however, you should ask for Trane OEM parts to avoid universal parts being installed;
  • All Trane heat pump models are Energy Star rated, and rebates are offered by many energy companies across the US when you install one of Trane’s more efficient models;
  • Both standard and Wi-Fi connected thermostats are available from Trane to coordinate system performance, and the Wi-Fi models can be controlled from a smartphone using the Trane app;
  • Financing from Trane is available to qualified customers.

Trane Heat Pump Cons

  • Trane’s most efficient heat pump, the XV20i with 20 SEER /10 HSPF efficiency is not as efficient as top competitors like the Carrier Infinity 20 and Bryant Evolution 280A (20.5 SEER/13 HSPF) and the Lennox XP25 (23.5 SEER / 10.2 HSPF).
  • Trane heat pumps cost more than brands including Goodman, Amana, Aire-Flo and Payne, and part of the higher cost is better quality, though part of it is Trane’s large advertising budget
  • While Trane warranties on the best models are average for the industry and comparable to those from Lennox and Carrier, Goodman, Amana, Heil, Maytag, Tappan and Tempstar are among brands that have longer warranties and those that include entire product replacement
  • Trane heat pumps cost more than Trane furnaces, though the extra cost will be recouped over time through lower energy bills

Things to Consider Before Purchasing a Trane Heat Pump

Your climate matters. In hot climates, it makes sense to pay more upfront for a model with a high SEER rating for efficient, environmentally friendly cooling. Your energy costs in the long-term will be much lower, for example, with the 20-SEER XV20i than with the 16 SEER XR15. The longer you intend to live in your current home, the better your savings will be. If you plan to move, having a high-efficiency system in place will be a strong selling point.

If your winters are very cold, installing a gas furnace instead of a heat pump or choosing a hybrid heat system with heat pump and furnace are better choices than a heat pump alone. The reason is that heat pumps lose effectiveness in freezing weather, and you must rely on the unit’s electrical heating – like space heating—which produces high energy costs. The cheapest way to heat your home in cold climates is a hybrid system, though the cost for the system is higher, and the payback time is 8-12 years.

Summing Up

Once you’ve selected the Trane heat pump right for your climate, make sure it is sized properly. Installing a unit with too much or too little capacity creates a range of problems from insufficient heating and cooling to temperature fluctuations to premature mechanical failure. Ask your contractor to do a load test to see what size heat pump you need.
