Is My Compressor Bad?
Think your compressor may be broken? Looking for clues is hard when you don't know where to start. Get to the bottom of your AC problem and put your detective skills to the test with this shortlist on how to check your AC compressor.
What to Check
Feeling the air discharged from your condenser fan can indicate whether it’s doing its job right. The air should be warmer than the air outside since it is releasing the heat that was removed from inside of your home. Increases in your electric bill and odd noises coming from your unit during the start-up process can also tell you your compressor is struggling. However, to truly test your compressor, an HVAC professional has to conduct an evaluation.
Some Like It Hot
Diagnosing a bad compressor can be simple if you know what to look for. An easy first step to solving this mystery is to feel the fan air temperature. Place your hand above the condenser fan to feel for warmth. Your condenser fan discharges heat removed from your home so if the air released is lukewarm or cold, there’s likely a problem.
When your compressor is howling up a storm or thundering along, it’s probably a sign it’s facing some turbulence. When your compressor breaks down, you'll hear loud noises like grinding and squeaking coming from your system as it runs. Listen for unusual sounds when you’re sleuthing around your system.
