4 AC Repair Issues (And What to Do About Them)

frozen-window-unitIt’s nice to know what problems can appear in your air conditioner so that you know what to look out for. What’s even better is knowing what to do after you find the problem!

1. Frozen Evaporator Coil

Normal air conditioner operation depends on two sets of coils: the evaporator coil and the condenser coil.

The evaporator coil’s job is to absorb warm air from inside your home. If it stops functioning properly, it will get so cold to the point of developing ice and frost. Ice on the evaporator coil is commonly mistaken as a good thing, but that couldn’t be further from the truth.

Frozen evaporator coils can block airflow, lower efficiency, and damage the compressor.

What to do: Turn off the system and let it defrost (don’t try to pick off the ice, as that can damage the coil). Change the air filter if it’s dirty and try running it again. If it freezes again, the problem could be something like a refrigerant leak, so turn it off and call in for AC repairs in Panama City.

2. Dirty Condenser Coils

Are your energy bills higher than usual? Is the home not cooling properly? A dirty condenser coil could be the cause.

The condenser coil is the coil that lives in the AC’s outdoor unit. This coil will release warm air, but if it’s covered in dust and dirt, it will act as an insulator instead. This can ruin the performance of the AC and could be the cause of your recent AC issues.

What to do: Call in a professional for help with cleaning.  If the coils have gotten so dirty that they’ve begun affecting performance, you’re better off calling a professional to have them clean it carefully and thoroughly. After that, they can inform you on how to keep them clean.

3. Dirty Air Filter

Your air conditioner uses an air filter to prevent dust and dirt from entering the sensitive components of the machine. When that filter becomes clogged, it can have adverse effects on the air conditioner. Restricted airflow can lead to inefficiency, frozen evaporator coils, short cycling, and a handful of other issues.

What to do: Change that air filter! Dirty air filters can create a range of problems that emulate other common and serious AC problems. So if changing the air filter doesn’t help, you should immediately call to have the real problem investigated.

4. Refrigerant Leaks

Refrigerant is a chemical that runs through your air conditioner like blood. It helps facilitate the transfer of heat, thus helping remove warm air from inside your home. Leaking refrigerant can freeze the evaporator coil, tank your efficiency, and damage the compressor over time.

What to do: It can be difficult to spot a refrigerant leak. A pinhole leak often won’t make hissing or gurgling noises until they’ve grown bigger. If you do notice it though, you’ll want to turn off the AC immediately. Leave it off until an HVAC technician has arrived to fix the leak, recharge the refrigerant, and has given the OK to turn it back on.
