AC Won’t Cool? Here’s Why

August 17, 2020

The hot and humid summers in Lake Charles, LA, mean you depend on your air conditioner for relief. The last thing you want is to wake up or come home to a sweltering house. Consider these three reasons why your air conditioner isn’t cooling your home and what you should do about each of them.

1. Dirty Filter or Coils

A dirty air filter hinders the flow of cooled and dehumidified air into the air ducts and living spaces of your home. If you barely feel a trickle of air from the vent, check the air filter first. If it’s dirty, replace it. Check the filter monthly and replace it every two to three months or sooner if it’s dirty. Another possible cause is dirty evaporator or condenser coils. These issues require professional attention.

2. Refrigerant Leak

If refrigerant leaks out of your cooling system, less heat can be removed from your home. Once too much of the refrigerant has leaked, the air conditioner won’t cycle. If you hear a hissing sound, this is likely from an active refrigerant leak. Only certified air conditioning technicians should check refrigerant levels, make refrigerant line repairs, or recharge the refrigerant.

3. Broken or Damaged Part

Air conditioners have a lot of parts. If just one of them wears out, cracks, or gets loose and breaks, the system won’t be able to cool your Lake Charles home. Some common parts that wear out include the capacitor, motor, and fan. A broken compressor is another common problem in older air conditioners. A bent fan blade, loose screw, or cracked belt may cause the air conditioner to automatically shut down. A clogged condensate drain may also prevent the air conditioner from cooling your home. The clog causes water to back up into the drain pan, which triggers most air conditioners to automatically power off.
