Heat Pump Noises That Indicate a Problem

Winter is one of the more stressful times of year for heat pumps, which makes it more likely that problems will develop with them. If you’re using a heat pump to keep warm this winter, you need to be keenly aware of any symptoms that indicate a problem with your system. One of the easiest ways to do that is by listening for any strange noises that come from the heat pump during operation.

Grinding

Your heat pump distributes heat throughout your home using a part called the air handler. The air handler is basically a motor with a large fan attached to it, which blows air through the ducts to circulate output from the system. The air handler motor generates a lot of friction while it’s operating, so it uses oiled bearings to help the system run more smoothly. These bearings will wear down over years of use, causing the friction on the system to rise. When the bearings are close to failing entirely, the friction might generate a grinding sound. You should call for repairs as soon as you hear this sound, before the air handler motor overheats and burns out.

Gurgling and Hissing

If you hear gurgling and hissing noises coming from your system, it likely means that there are air bubbles in the refrigerant line. A leak in the refrigerant line will drain the system, causing its output to drop and eventually resulting in a full system breakdown. If you hear this happening, especially if it’s accompanied by an obvious leak, call for a professional immediately.
