How to Know if Your Air Conditioner Is Frozen
I was sweating bullets. It was the middle of summer, and my air conditioner had stopped working. I tried turning it off and on again, but that didn’t do anything. I was about to call an AC repairman when I remembered something I had read online.
Apparently, air conditioners can freeze up if they’re not properly maintained. I decided to give it a try, and sure enough, there was a thick layer of ice on the coils. I was able to defrost the coils and get my AC working again in no time.
What Causes an Air Conditioner to Freeze?
Air conditioners work by removing heat from the air in your home and transferring it outside. The coils in the AC unit absorb the heat from the air, and the refrigerant inside the coils then carries the heat outside. If the coils are blocked or dirty, the heat can’t be transferred properly, and the coils will start to freeze.
Signs That Your Air Conditioner Is Frozen
There are a few telltale signs that your air conditioner is frozen.
- Reduced airflow. If the airflow from your AC unit is noticeably reduced, it could be a sign that the coils are frozen.
- Ice on the coils. If you can see ice on the coils, it’s a sure sign that they’re frozen.
- Strange noises. If you hear strange noises coming from your AC unit, such as popping or banging, it could be a sign that the coils are frozen.
- Higher energy bills. If your energy bills have been increasing lately, it could be a sign that your AC unit is working harder to cool your home because the coils are frozen.
How to Defrost a Frozen Air Conditioner
If you think your air conditioner is frozen, there are a few things you can do to defrost it.
- Turn off the AC unit. The first step is to turn off the AC unit at the thermostat. This will stop the compressor from running and allow the coils to defrost.
- Remove any obstructions. If there are any obstructions blocking the airflow to the coils, such as furniture or curtains, remove them.
- Wait for the coils to defrost. It can take several hours for the coils to defrost completely. You can speed up the process by using a fan to circulate the air around the coils.
- Turn on the AC unit. Once the coils are defrosted, you can turn on the AC unit again.
Tips for Preventing Your Air Conditioner from Freezing
There are a few things you can do to help prevent your air conditioner from freezing.
- Change the air filter regularly. A dirty air filter can block the airflow to the coils, which can lead to freezing.
- Clean the coils regularly. Dirt and dust can build up on the coils over time, which can also lead to freezing.
- Don’t set the thermostat too low. Setting the thermostat too low can cause the AC unit to overwork itself, which can lead to freezing.
- Have your AC unit serviced regularly. A qualified HVAC technician can inspect your AC unit and make sure it’s working properly.
