Your air conditioner, just like other appliances, can break down when it’s working its hardest. Being aware of the top AC problems that you’re likely to experience will help you identify the signs of a faulty AC system and take preventive measures to avoid them. Below are the top AC problems you may encounter.

Refrigerant Leaks

A refrigerant leak is a common AC problem that affects your system’s performance and efficiency. Refrigerant leaks harm the compressor and the environment. Your air conditioner failing to cool your home properly, bright stains close to your AC unit, and bubbling or hissing noises are common signs of a refrigerant leak.

Frozen AC System

Ice can form around your AC coil or copper lineset, disrupting regular air conditioning, making it one of the top AC problems. The problem commonly occurs because of debris buildup that makes your unit fail to receive adequate air to function normally.

Indoor Water Leak

A water leak from the indoor AC unit indicates poor AC maintenance. You may have a broken-down condensate pump, or the condensate drain may be clogged with fungi or algae.

Outdoor Water Leak

A pool of water may form under the outdoor compressor because of several reasons, including:

  • Dirty filter
  • Poor AC seal
  • Cracked condensate pan
  • Incorrect installation

Air Conditioner Not Blowing Cool Air

Your air conditioner may run without any cool air coming out of your ducts. Alternatively, the air being blown may not be adequately cool. That could be due to a faulty thermostat, low levels of refrigerant, vent blockage, duct leaks, problems with the blower motor, or a tripped circuit breaker.

Weird Sounds

Strange AC sounds usually signal an internal issue. Squealing noises typically result from a poorly aligned or worn-out belt. A capacitor problem or obstruction in your fan will cause clicking noises. Grinding noises point toward a motor or compressor failure.

Strange Odors

Strange smells are a common sign of AC issues. If you have clogged air filters, your system may overheat and emit burning smells. Wiring issues could cause electrical smells.
