Is Your Newton Grove, NC Heat Pump’s Compressor Failing?

April 8, 2024

Compressors function as the heart of heat pump operations by pressurizing and pumping refrigerant throughout these systems. Easily the most expensive component in your heat pump, the compressor can lose efficiency or outright fail. The following are several ways to know when you have a faulty heat pump compressor in your Newton Grove, NC home.

Loud and Jarring Sounds

If you hear loud screeching, shrieking or banging sounds from the outside unit, they may be coming from your heat pump’s compressor. Buzzing noises indicate electrical problems, and hissing could mean that you have a refrigerant leak. Given that heat pump compressors are highly pressurized, continuing to run them with refrigerant leaks or other progressive issues could result in premature failure or collapse.


Heat pumps can overheat due to insufficient maintenance. The buildup of debris that restricts airflow can trigger emergency shut-offs so that heat pump motors don’t burn out. Fortunately, overheating is often easily resolved with professional HVAC maintenance.

Poor Airflow

Conversely, if your compressor is failing, it can result in a weak airflow. If you detect a weak output of air at your air registers or vents, it’s time to have your heat pump inspected.

The Wrong Heating or Cooling Output

When in heating mode, heat pumps should always distribute heat. When they’re in cooling mode, the air coming out of your vents should always be cold. If your heat pump is blowing out cold air in winter and warm air in summer, the problem could be an incorrect thermostat setting or a failing compressor.

We help homeowners extend the lifespans of their heat pump compressors with routine maintenance and timely repairs. For expert heat pump service in Newton Grove, NC, contact Cape Fear Air Conditioning, Heating, & Electrical Company, Inc. today!
