4 Heat Pump Noises and What They Mean in Bath, PA | Kitchener ON

It is normal for your heat pump to make some noise as it cools your home in Bath, PA, though this will largely occur at the start-up. Loud, prolonged noises in a heat pump signify something is wrong. Below are four such noises and what causes them.

Rattling and Clanking

Some parts, especially cover panels, can become loose in the unit, in which case they will rattle throughout the cycle. Out-of-balance parts can rattle as well. Clanking is likely the result of the fan blade hitting against a loose object or the fan blade itself being loose.

Metallic Grinding

This usually points to bad motor bearings in the air handler. The bearings allow for rotation within the motor, so they can start to grind when worn out or lacking lubrication.

Squealing

Bad motor bearings can also produce a squealing or other high-pitched sound. The sound can also arise from a leaking discharge valve. Fortunately, an air conditioning repair could address these and other issues.

Hissing

Your heat pump circulates refrigerant in order to absorb heat from your indoor air and send it outside. The refrigerant lines can develop a leak, though, and when they do, they sometimes produce a loud hissing sound. Most of the time, you’ll notice the air becoming lukewarm, then you’ll want to have a technician over right away.
