Why Is My Heat Pump Making Weird Noises?

If you want to keep your heat pump in the best possible condition, you’re going to need to become skilled at identifying possible problems as early as possible. The faster you can identify problems, the faster you can get them repaired and the more damage you can prevent. One of the best ways to detect problems early is to listen for strange noises coming from the heat pump. Let’s take a look at some of the strange sounds that can indicate a problem with your heat pump system.


As with most climate control systems, heat pumps use air handlers to move air throughout the home during operation. The air handler in your heat pump is equipped with a number of oiled bearings, designed to reduce friction on the system while it’s operating. These bearings will wear down over time, however, causing the friction on the system to increase and generating a loud grinding sound. If you hear this sound, call for repairs as soon as possible. If the bearings are not replaced, the friction will increase until the air handler motor burns itself out.


Gurgling and hissing sounds indicate that the heat pump has air bubbles in its refrigerant line. This indicates that you have a leak in your system, which is draining refrigerant from it. Refrigerant is the lifeblood of the heat pump; without it, the system will eventually break down. If you hear these sounds, especially if they are accompanied by dropping output or visible fluid leaks, you should have a professional examine your system before it breaks down entirely.
