If you have noticed that your AC unit doesn’t quite cool your home the way it used to, or it is working harder to cool your home, which can also increase your energy bill, an AC frozen inside could be the problem. An AC frozen inside can be caused by a number of components, which this short tutorial will help you troubleshoot.

Common Issues with an AC Frozen Inside

There are various common issues that can occur due to an AC frozen inside, which include:

A Lack of Airflow

An AC frozen inside can cause a lack of airflow, which can make your unit blow out warm air or struggle to cool your home. When this occurs, it can cause premature wear on your unit as well as increase your energy bill as the unit works harder to perform its function.

The A/C Stops Working

If you notice that after running the A/C unit for some time, it freezes up or stops working altogether, ice buildup could be to blame. An AC frozen inside literally causes ice to form on the unit’s interior parts, which blocks air to the system and in turn can cause it to stop working.

Ice or Frost Buildup on the Unit’s Parts

Low airflow to the A/C unit causes a decrease in temperature inside the system, so when moisture in the air collects on the unit’s components, it can create ice buildup on both the inner and outer parts of the A/C.

Never attempt to remove ice from your system by picking or scraping it off with a sharp object because it could damage the parts and lead to costly repairs. Instead, simply turn off the system and wait for it to thaw, or turn on the blower to allow it to thaw, before troubleshooting it.

Tools You’ll Need for the Job

Nut Drivers and Sockets

When troubleshooting your system, you will need to access the system’s inner parts. Therefore, you will need a set of nut drivers and sockets to remove the panels to inspect the parts.

A Soft Brush

A soft brush, such as a toothbrush, can be used to remove debris from a dirty air filter, which can hinder proper airflow to the system and cause it to freeze up. It can also be used to gently remove debris from the evaporator coils, which can also cause the A/C to freeze up.

A/C Frozen Inside Troubleshooting

There are two main causes of an AC frozen inside, which include low refrigerant and restricted airflow to the evaporator coils.

Turn off the A/C

First, turn off the AC, and turn the fan setting on to allow the system to thaw. Place dry towels around the unit to prevent water damage.

Open the Access Panel to the Evaporator

Remove the access panel to the evaporator. Inspect the coils and the cooling fins surrounding the evaporator. If they have debris on them, gently brush it off using a soft brush.

Check the Air Filters

Check the filters in the cold air return inside your home or in the AC’s plenum to see if they are dirty, which can restrict airflow to the system. If they are dirty, simply clean them gently with a soft plastic brush or replace them if they are beyond cleaning.

Check for Refrigerant Leaks

To effectively cool your home, the AC needs the right amount of refrigerant. However, over time, wear and tear on your system can lead to refrigerant leaks, which can cause the temperature of the coils to decrease and eventually cause ice buildup.

Therefore, inspect in and around the system for visual signs of refrigerant leaks, sometimes they can also cause a soft hissing sound. If you find any leaks, simply contact a professional HVAC technician to repair the leaks and then recharge your system.

Turn the A/C Back On

Be sure the A/C supply registers in each room are open. Blocked registers restrict airflow, which causes the temperature inside the unit to decrease.

Turn the A/C back on and allow it to run until it reaches the thermostat setting. If the air still feels warm, the unit still struggles to cool your home, it continues to shut off, or you still notice ice build up on the unit, contact a professional HVAC technician for repairs.

Other Issues that can be Causing an AC Frozen Inside

• The Wrong Size Ducts – Sometimes the wrong size or number of ducts can cause restricted airflow, which can also cause your system to freeze up.
• The Wrong Size Condenser – The condenser size, or BTU’s, is determined by several factors regarding your building, including the size of the building, how hot the building is, the amount of insulation is inside the walls, and the type of windows. Therefore, if you have the wrong sized condenser for your needs, it can cause the system to freeze up.
• A Bad Blower Motor – Consistent use and high heat can cause the blower motor on the A/C to burn out, which can cause your unit to freeze up.

Caution Notes

Working with refrigerant, which can be a gas or a liquid, requires a licensed professional, so when dealing with refrigerant leaks and repairs, be sure to contact a licensed professional for help.

Final Thoughts

To prevent premature wear and tear on your A/C, which can cause it to clonk out before its time, and to help keep your energy bills low, don’t put off AC frozen inside repairs. Instead, use this short guide on what to do about AC frozen inside to troubleshoot the issue, and then make the repairs that you can yourself to help save time and money.

There is nothing more annoying than your air conditioner failing to work in the middle of a heat spell. In such circumstances, you may have to wait for days before an HVAC technician can repair your unit. In most cases, air conditioners repairs should be handled by HVAC technicians, but there are simple repairs you can do yourself with a little air conditioner troubleshooting. This guide will explore some of the most prevalent problems and how to fix them.

Tools for the Job

Apart from parts that you may need to buy depending on the nature of repair required, you also need to have working tools. Here are most of the tools that you need to complete your DIY project.

• Cordless drill or driver.
• Nut driver.
• Adjustable wrench.
• Voltage tester.
• At least 2 insulated screwdrivers.
• Pliers- Needle-nose.
• Socket set.
• Multimeter.

You may also require some materials before you initiate air conditioner troubleshooting. This will eliminate unnecessary last-minute trips to stores. Here is the list of the main materials:

• Fuses.
• Capacitor.
• Contractor.
• Compressed air.
• Condenser fan motor.

Air Conditioning Problems

Your AC Unit Won’t Turn On

If your air conditioning system fails to start, there could be a range of potential causes that you need to check out. First, check if the condenser is running, then confirm if the thermostat is set properly and make sure the AC is plugged in. One of the challenges could be the setting on the thermostat. You can start air conditioner troubleshooting by lowering the thermostat to 5 – 10 degrees and observe if the unit will work.

Another potential problem could be the fuse. Check if the fuse is blown. If not, then check if tripped circuit breaker or loose wiring is the problem. To test the fuse, you need to set your multimeter to a lower Ohms scale then place the black and red leads on the opposite ends of the fuse. Zero, infinity symbol, or minus reading indicates a blown fuse. A blown fuse could also be a sign of failure in the condensing unit.

You may also need to inspect internal part of the access panel. The best way is to follow the electrical conduit to find the access panel. After putting the power off, you need to check if the electrical wires and connectors are intact. If there is any chewed insulation, fix them if you are comfortable with electrical repairs, otherwise, engage a professional. Besides this, you may need to replace the capacitor and contactor. These items can degrade with time.

If you replace the fuse and it blows up again, or if the unit won’t turn on after you have done the above replacements, or if the coil is frozen, the problem could be the compressor or motor. At this point, it is best to contact your HVAC professional to fix the problem.

Your AC Unit Is not Cooling Air or Isn’t Working Optimally

Even if the thermostat settings are correct, your AC system may still fail to work. A potential problem could be the system has a blocked air condenser, or it is dirty. The first step is to make sure all the register are wide open and the furnace filter is clean. You can then clean the unit from outside to remove any weeds or debris that may be blocking the free flow of air.

You also need to check the filter. Oftentimes, the filter may accumulate a lot of dirt, which may prevent the flow of air to the evaporator coil. So, as you carry out your air conditioner troubleshooting, you can test if your filter is working by seeing through it.

You should change your filters at least once a month if you are constantly using your AC unit or if you have pets. If the filter is working, and your AC still fails to work, then the problem could be linked to the refrigerant or compressor.

Leaking Refrigerant

One of the problems that you will deal with in your air conditioner troubleshooting is refrigerant leaks. If your AC unit is low on refrigerant then there are two potential dangers. The unit might be undercharged at installation or the refrigerant is leaking. The refrigerant is the fluid mixture that keeps everything cold.

To fix refrigerant leaks, you will need a trained technician. These leaks can be harmful to the environment. According to Energy Saver, your air conditioner functions optimally when the refrigerant is charged according to manufacturer’s specifications.

Leaking Ducts

Another potential culprit that may prevent your AC unit from working is leaking or dirty ducts. If you are getting warmer air than you expect, then there could be a problem with ducts. Generally, the central air conditioning system is well sealed, however, the ductworks that run through the ceilings and walls could develop leaks due to poor workmanship or rodents. If there are leaks in the ducts, the cool air will escape before reaching your room. Part of the air conditioner troubleshooting could also involve checking the window seals around the AC system to ensure hot air is not getting in.

Besides checking for leaks, you should also need to regularly clean your AC unit, for instance, replacing filters on a monthly basis, cleaning the condenser and evaporator coils, and clearing the drain lines at least two times a year.

Caution Notes

Before you start fixing anything on your air condition system, ensure you have turned off the power. Turn off the power at the breaker box inside then do the same to the exterior shut-off box close to the exterior condenser. If you are not sure about a specific situation, especially the ones that touch on the electrical and the core of the system, please involve a professional.

Wrapping Up

If there’s one thing that you need to remember from this discussion on air conditioner troubleshooting is to have a routine maintenance plan. Even if the above troubleshooting doesn’t work, at least you already covered most common problems. So, your HVAC professional can focus only on the elusive challenges. Moreover, when you fit new parts on your AC unit, you are extending their lifespan as well as reducing chances of breaking down.

Air conditioners are one of the more important purchases one can make. In a best case weather scenario they turn an uncomfortable day into a refreshing one. And in a worse case weather scenario they can literally save people’s lives.

Knowing one can depend on an air conditioner largely depends on the brand. In this article we’ll go over the best air conditioner brands. This will demonstrate how one can get a great air conditioner by going with great brands.

7. LG

The best air conditioner brands are those which meet criteria one cares about. LG ranks a bit lower for some of the more common metrics which most people value. They’re located in Korea, which can make support rather difficult. And they haven’t been around for very long in comparison to some of the other companies.

LG has connections to Goldstar. But they were only solidified as a separate entity in 1995. This makes them a fairly young company. However, they do quite well when it comes to price.

Their price range goes as low as around $150. And their BTU ranges gos from around 5,000 to 14,000. This makes them a good match for people who primarily want to get a good deal and don’t need further support.

6. Whirlpool

Whirlpool is a respectable air conditioner brand. It dates back to 1911 so it has an impressive longevity. On top of that, over 106 years of service has always come from within the United States. This makes it easy to get additional support if needed. And one can assume that they’ll be around for some time to come.

Their range goes from around $300 to $600. And these provide BTU ratings from around 8,000 to 24,000. It’s usually a good value. But they drop down in rankings a little due to over diversification in product line.

A company heavily focused on air conditioners can provide the best overall support and development. However, Whirlpool has a very diverse line of products. Some might feel that this makes them a less the perfect match for the highest spots on a best of list.

They’re obviously quite good. But Whirlpool seldom provides really cutting edge air conditioner units.

5. Haier

Haier ranks a little lower on the list due to location. The fact that they’re located in China reduces their overall ability to offer support. One can certainly still expect basic service if a unit incurs damage. However, this is usually far more limited than one might expect from local companies. But at the same time, they have some advantages in manufacturing costs.

Those advantages translate to fairly good prices on higher performance items. For example, their BTU range goes from around 5,000 to 24,000. The prices are fairly impressive though. They’re able to sell fairly powerful units at only $100 to $500.

4. Kenmore

Kenmore’s higher ranking comes from overall notability. If anyone hears the name Kenmore they’re usually going to recognize the company. Part of this comes from longevity. They’ve been around since 1913. In that time they’ve been able to maintain a highly positive reputation.

Additionally, they’re located within the US. This makes any kind of support fairly easy for customers. They also have a fairly good return on value. Their BTU range is around 5,000 to 24,000. And the overall price range for that value is quite impressive as well. It’s only $100 to $700.

3. GE

Recognition factors in when one considers the best air conditioner brands. GE certainly has brand recognition among the public. But they’re also usually recognized as the market leader in windowed air conditioners.

They don’t offer the best value on the list. In general their BTU range goes from 5,000 to 25,000. And their prices go from $150 to $300. While not the absolute best value, it’s still quite respectable. And the fact that it’s from such a well known brand pushes it even higher on this list.

2. Friedrich

The best air conditioner brands need to be around in the future. This provides an automatic bonus for Friedrich. They’ve been around all the way back to 1883. That suggests that one can depend on them in the future as well.

However, they rank a little lower on the list due to some overall specialization. Their least expensive models tend to sit in the mid-range. With a BTU rating of around 5,000 to 24,000. And their cheapest prices tend to hover in the $200 range. However, many of their units sell for over $1,000. The upper range sells for around $1,200.

All of these factors make them a company one can depend on. However, in general they’re most useful for people willing to make a fairly significant investment.

1. Frigidaire

The best air conditioner brands are those which hit as many important metrics as possible. Frigidaire meets a number of these important points. Among the first is longevity. Frigidaire’s history dates all the way back to 1918. As such, it’s safe to assume that they’ll be around for some time to come.

They also have a respectable BTU range. It goes from about 5,000 to 28,000 BTU. Their high ranking comes from combining these with the final trait. The longevity and high performance comes at a surprisingly low price. Their models sell from around $100 to $800.

Wrapping Up

The next step involves choosing between the best of the best. Any of these brands offer solid options. But one needs to consider the best match for particular lifestyles and homes. For example, choices of brand might depend on whether one wants a large or small unit.

The best air conditioner brands should serve as a perfect guide. It’s a matter of considering one’s needs and acting on them. Though talking over personal experiences with the brands can also help.

Having your air conditioning fail or not working properly in the middle of the sweltering summer can really make your home uncomfortable. Therefore, it is recommended that you keep an air conditioning preventive maintenance checklist to help you stay on top of repairs and keep your system running smoothly and efficiently and avoid unexpected breakdowns, which can be especially harmful to allergy sufferers, those with respiratory conditions, and more.

To comprise an air conditioning preventive maintenance checklist is simple and only requires the following 3-step process.

3-Step Preventive Maintenance Checklist

An air conditioning preventive maintenance checklist enables you to note the condition of your system as well as schedule routine maintenance on major components in order to keep your system running as it should, which helps save time and costs on emergency repairs.

1. Overall System Checklist

• Turn the A/C Unit on, and Perform a General Observation of Your System. Observe that the system starts up promptly and responds to the thermostat’s temperature adjustments. You should also inspect that the thermostat is functioning properly and is maintaining the proper temperature. Listen for unusual sounds and smells, and check that the vent is working properly. Lastly, turn the unit off and make sure it shuts off properly.In other words, observe that the system functions according to the manufacturer’s specifications.

2. Indoor Equipment Checklist

• Replace or Clean the Air Filters. To keep your A/C running efficiently, it must have a clean filter. Therefore, you should clean the air filter periodically. Also, change your filter at least every 90 days in order to maintain proper airflow.
• Inspect the Control Box, Connections, and Wiring. Loose or disconnected electrical connections can cause your A/C unit not to come on. Therefore, inspect all of your electrical connections and wiring as well as the control box. Tighten electrical connections as needed to keep your A/C up and running.
• Observe the Condensation Drain, the A/C Drain Line, and the Evaporator Coil. The condensation drain and the A/C drain line enable moisture to empty from your system. However, if they are blocked, it allows moisture to build up in your system, which can damage the A/C. Therefore, periodically inspect the condensation drain as well as the drain line to ensure they are dirt-free, and there is no moisture accumulation. You should also inspect that the evaporator coil, which is the part of the system where the refrigerant absorbs heat, is free of dirt because it can affect how much the refrigerant can be absorbed.
• Inspect the Blower and the Blower Housing for Debris. Dirt and other contaminants can accumulate on your A’C’s blower, which can hinder its operation. Therefore, you need to clean the blower periodically to ensure your system functions properly.
• Inspect the Fan Belt and Lubricate the Moving Parts. The A/C system includes various moving parts, including the fan belt, which require smooth movement in order to function properly. Therefore, be sure to lubricate any moving parts. Change the fan belt when needed to keep your system running smoothly.
• Observe the Duct-Work for Leaks. Duct leaks in anywhere in your system can hinder efficient airflow. Therefore, inspect for duct leaks in and around your system, and have any leaks properly repaired in order to maintain sufficient airflow.

3. Outdoor Equipment Checklist

• Clean Dirt, Leaves, and Debris from Inside and Around the Unit. Leaves, pollen, twigs, grass clippings, and other debris during the warmer seasons can fall on top of, on the sides of, and inside of the outdoor A/C unit, which can hinder its function. Therefore, be sure to keep your outdoor unit clear of debris in order to help maintain proper function.
• Observe the Fan Blades, the Fan Motor, the Coils, and the Wiring. Clogged coils outside can force your A/C to work hard, which can require more power to operate your system. However, keeping your coils clean can keep your system running at peak efficiency. Meanwhile, worn or loose fan blades and wiring can create a fire hazard, especially if the fan blades are positioned near wires. Loose belts on the fan motor can cause the motor to overheat, which can also be hazardous. Therefore, be sure the fan blades, the fan motor belts, and the wiring are tight in order to avoid potential dangers.
• Observe the Unit for the Proper Refrigerant Level. Maintaining the proper refrigerant levels not only helps keep your air cool, but it also helps protect the environment. Spilled or leaking refrigerant can cause chemical effects. These can be hazardous to your health as well as to the environment, and it can even damage your system.
• Observe the Tubing and the Compressor for Damage. The compressor stores refrigerant, which is responsible for interchanging hot and cold air between the inside and the outside. If the compressor tubing leaks refrigerant, then it affects the cooling efficiency of your unit, which can increase the cost to cool your home. Therefore, inspect the tubing for leaks to keep your system cooling efficiently.

Final Thoughts

An air conditioning preventive maintenance checklist helps save time and money by allowing you to stay up on your system’s operation and repairs. Once you have created your air conditioning preventive maintenance checklist, simply perform the repairs you can yourself and keep a running record of repairs for your technician. You should perform routine maintenance on your system at least once a year to help ensure proper maintenance in time for the summer.
