A bad compressor can be a real bummer, especially during the hot summer months. If your AC unit's compressor is malfunctioning, you might notice a decrease in cooling performance.

One of the first signs of a bad compressor is a loud rattling or clunking noise coming from the unit. This is often a result of a worn-out or loose part.

A compressor failure can also cause your AC unit to leak refrigerant, which can lead to a significant increase in your energy bills. In fact, a single leak can cause your unit to lose up to 20% of its cooling capacity.

If you suspect your compressor is bad, it's essential to turn off your AC unit immediately to prevent further damage.

Common Symptoms

Diminished airflow is a subtle yet important sign of a bad compressor, often harder to spot than loud noises or chemical leaks. It can also indicate clogged ductwork.

Reduced airflow can lead to warmer air coming out of your vents, which is a clear indication that your compressor is low on refrigerant. This is a sign that you need to call a professional to find out why.

Here are some common symptoms of a failing AC compressor:

  • Loud noises
  • Hot air
  • Less powerful airflow
  • Uneven cooling
  • Electrical problems
