If your air conditioner or heat pump isn’t keeping your home as cool or comfortable as it should be, the compressor could be to blame. The compressor is often called the “heart” of your cooling system—it pumps refrigerant through the system so that heat can be transferred out of your home. When it starts to fail, the entire system struggles to perform. Be on the lookout for these warning signs of a failing compressor.

1. Lack of Cool Air
One of the most obvious signs of compressor trouble is a lack of cold air. If your AC is running but blowing warm or lukewarm air, the refrigerant may not be circulating properly. This could be due to low refrigerant levels, but it could also point to a compressor that isn’t functioning effectively. If your system used to cool just fine and suddenly doesn’t, call a professional to check the compressor.
2. Unusual Noises
Compressors typically make a low humming sound when operating normally. If you hear clattering, ticking, growling, or screeching noises coming from your outdoor unit, it may indicate internal damage or failing components inside the compressor. These noises can precede a complete compressor breakdown, so don’t ignore them.
3. Frequent Tripping of the Circuit Breaker
If your outdoor AC or heat pump unit keeps tripping the breaker, it could be because the compressor is drawing too much power. This might happen if the compressor is struggling to start, overheating, or seizing up. Constant circuit breaker trips are a serious electrical safety issue and require immediate attention from a qualified HVAC technician.
4. Compressor Won’t Turn On
Sometimes, the rest of the AC system seems to be running—the fans are blowing, and the thermostat is calling for cooling—but the compressor doesn’t turn on. This could be due to electrical problems, a bad capacitor, or internal compressor failure. If you suspect the compressor isn’t engaging, a professional diagnosis is essential.
5. Vibrations or Shaking at Startup
When the compressor is trying to start but can’t quite get going, you might notice the outdoor unit shake or vibrate excessively. This is called “hard starting,” and it’s a sign that the compressor is having difficulty powering up. Hard starting puts extra stress on the compressor and other electrical components, shortening the life of the system.
Time for a Repair or Replacement?
If your compressor is showing one or more of these signs, it’s time to call an HVAC expert for a thorough inspection. In some cases, compressor problems can be repaired, especially if caught early. However, if your system is older or the compressor is severely damaged, a full replacement may be the most cost-effective solution.
