What’s Causing These Heat Pump Noises in Richmond, VA?

The heat pump in your Richmond, VA home should not make any other noise than a soft hum while it operates and a click sound when it turns on or off. Any other sounds signal trouble. There are a number of heat pump sounds you need to listen for because these mean that you have a problem that needs attention.

1. Rattling Noises

Many components work together to keep your heat pump running. If one of those parts, such as a bolt or fan blade, becomes loose, it could move around during operation and potentially cause damage to your system. The noise may sound like rattling or thumping.

2. Hissing or Gurgling

If the piping that houses the refrigerant springs a leak or if a connection loses its seal, refrigerant could escape and make a hissing sound in the process. If air gets into the refrigerant lines through the compromised area, you might hear a gurgling sound.

As soon as you hear these sounds, shut off your system and seek help immediately. An HVAC professional must handle this problem, as the substance is toxic and can cause severe irritation to the skin and lungs.

3. Buzzing Noises

The capacitor gives the heat pump the power that it needs to get started and continue to run. With a broken capacitor, your heat pump might make a buzzing or clicking noise because it’s having trouble starting or staying on. An HVAC technician can run diagnostics and determine whether this is the problem.

4. Grinding, Squealing, or Rattling

An old motor could make a few different noises that signal a need for repair. For instance, damaged motor bearings could result in grinding or squealing, and a damaged motor fan belt could make a high-pitched shrieking noise. Loud rattling might also mean that you have loose fan blades.

If you hear any noises, take action sooner rather than later to prevent problems from worsening and draining your wallet. Call to schedule a repair appointment with the team at Classic Comfort Heating & Air Conditioning.
