Pay attention to these heat pump noises:
Grinding during start-up: If you hear a harsh grinding sound when your heat pump comes on, then it could be “hard starting” because of a problem in the compressors—a heat pump uses two different compressors, so you will need a professional to find out which one is having difficulty.

Clanging and striking: The likely culprit here is a loose blower fan belt. A heat pump uses different fans to move air for the condensation and evaporation processes; if the fan belt develops damage or cracks, it could come loose and start hitting against other components. This needs to be addressed immediately, before the belt starts to cause more damage. The noise could also come from loose motor mounts.

Hissing: This usually indicates a leak in the refrigerant, which is responsible for the heat exchange that allows your heat pump to heat and cool your home. If you can hear it, it is probably a large leak and you won’t have a working heat pump for long. Get a professional to seal the leaks and recharge the lost refrigerant.

Humming and buzzing: There are a few reasons for hearing this sound (usually within the outdoor unit). One is that the run capacitor which keeps the motors operating has developed a fault. It could also indicate a stuck relay or a motor on the verge of a burnout.
