Why Is My Heat Pump Making Loud Noises?

It’s not unusual for a heat pump to make noises, especially when it’s starting up or turning off. You should familiarize yourself with its normal sounds, such as a swooshing noise when it goes into defrost mode. That way you’ll know when loud noises are a cause for concern.

Clanging

When you hear this noise, turn the heat pump off and inspect the fan. This sound usually means the fan blades are hitting something inside of the unit. It could be a small branch, a chunk of ice, or a part that’s come loose.

You’ll likely need to have your heat pump serviced by a professional. Not doing so can cause extensive damage. For people in Cheyenne, WY, Advanced Comfort Solutions is a trusted HVAC company that services heat pumps.

Squealing

This sound isn’t always a problem, as the screw compressor will often make it. However, if it’s a new loud noise, it may mean the motor is going bad or the refrigerant is overcharged. Another sign there’s a problem is if you can’t get your home to a comfortable temperature.

Buzzing

You may hear this noise in the winter when it’s nothing to worry about. However, if it’s loud and outside of heating season, it may mean the compressor is failing or the motor is malfunctioning. There could also be an issue causing electricity to arc between circuits.

Rattling

If your heat pump is loudly rattling or vibrating, it could be one of several problems. It might be a minor issue solved by putting a rubber pad under it. Other causes include the refrigerant tubing being strapped too tight or a loose cover panel.
