Answer: Why Is My Heat Pump Making Loud Noises?
Unusual noises from a heat pump indicate specific issues. A squealing or screeching noise from the outdoor unit often points to a failing fan motor bearing. A grinding or rattling sound may indicate a loose or damaged fan blade hitting the housing. A buzzing noise could be a loose panel vibrating or an electrical issue. Hissing or bubbling sounds may indicate a refrigerant leak. Gurgling noises during defrost cycles are normal (water melting and draining). If you hear persistent unusual noises, turn off the heat pump and call for service — continued operation can lead to more extensive damage.
