All air source heat pumps produce some degree of noise when in operation. The most common causes of air source heat pump noise include:
1. Compressor operation
Produces a low humming or vibrating sound
2. Fan rotation
Air turbulence produces moderate noise
3. Water pumps and water flow
Can cause water to gurgle or hiss
4. Pipe vibrations
Poorly secured pipes may cause rattling noises
Some noises from an air source heat pump are completely normal. However, if an air source heat pump makes loud or irregular noises, it needs to be checked. For example, a rattling sound may indicate a loose part, while a high-pitched whistling sound may indicate a problem with the refrigerant.
