Recognizing the Signs: When Your Heat Pump Needs Repair or Replacement

Your Heat Pump Won’t Cool

When your heat pump isn’t cooling effectively, it may again point to a malfunctioning reversing valve or a connection issue with your thermostat. Double-check that your thermostat is set to “cool” and assess the airflow from the vents. If there’s no airflow, the thermostat or the pump may need replacing. If air is coming out lukewarm, it could indicate a dirty pump or air filter.

Your Heat Pump Is Constantly Running

If your heat pump runs continuously, a miscalibrated thermostat may be to blame. Extremely cold weather can also cause extended running times. Additionally, a broken compressor contactor, which regulates power flow, might be causing the issue. This will require professional diagnosis and repair.

Odd Noises or Strange Smells Are Coming From Your Heat Pump

Heat pumps naturally produce noise, but if you hear rattling or screeching sounds, it could signal a loose part or a leak. Inspecting loose cover panels can be a quick fix, but other issues may require a professional. Similarly, if you detect unusual odors—like a rotten smell indicating an animal problem, a musty odor suggesting mold, or a burning smell indicating electrical issues—turn off the unit immediately and consult an expert.
