Is Your AC Running But Not Cooling? It Might Be Time for a Compressor Replacement

If your AC is on but not cooling, there’s a good chance the issue lies with the heart of your system: the compressor. This critical component is responsible for pressurizing and circulating refrigerant — without it, your air conditioner becomes a noisy, energy-draining fan.

AC compressor replacement can sound intimidating, but ignoring the signs may lead to more costly breakdowns and unnecessary energy waste.

Signs You May Need an AC Compressor Replacement

1. AC Compressor Is Running But Not Cooling

Your outdoor unit hums, the fan spins, and your home stays warm. If the refrigerant isn’t being compressed properly, the cooling cycle breaks down, even though your system “sounds” like it’s working.

2. Tripped Circuit Breaker or Frequent Shut-Offs

Compressor failure can cause the system to draw more power than usual, often tripping the breaker or causing short cycling (turning on and off rapidly).

3. Strange Noises from the Outdoor Unit

Grinding, rattling, or clicking noises often signal internal compressor issues. Worn bearings or failing motors can sometimes be repaired, but in many cases, replacement is the better long-term solution.

4. Warm Air or Inconsistent Cooling

One room cools, another doesn’t — or none at all. If you’ve ruled out thermostat, filter, and refrigerant issues, the compressor may be the reason.

5. Age of the Unit

A full compressor replacement may be more cost-effective if your air conditioner is over 10–12 years old and has compressor issues.
