Have you ever been sitting at home enjoying the cool air-conditioned atmosphere when suddenly you hear a strange noise? Upon investigating, you discover it’s coming from your ductless AC system. Here are four troubling ductless AC system noises you don’t want to ignore in your Mountain City, GA, home:

Grinding Noises

The air handler in your ductless AC system contains oiled bearings. The bearings prevent excessive friction within the AC system as it operates. Over time, these bearings become worn, decreasing their effectiveness and causing a grinding sound as friction increases.

Hissing Noises

A shrill hissing or whistling sound from your mini-split AC system, either the indoor or outdoor component, most often indicates a leak somewhere. Most often, this turns out to be a refrigerant leak. This type of leak is extremely serious because your ductless AC system can’t move the hot air out without the right amount of refrigerant to keep your home cool and comfortable.

Short-Cycling Noises

The sound of your ductless system running for a very brief time, shutting off, then starting up again right away means the system is short cycling. This indicates either a problem with the compressor or the thermostat. Left unchecked, these problems have the potential to affect your ductless AC system’s performance and lifespan negatively.

Buzzing Noises

A buzzing or vibrating sound coming from your system means you should have your outdoor compressor component checked for electrical issues. Neglecting to do so most often results in increased utility bills and energy and efficiency. This type of noise also comes from broken/loose fan blades or other components, fan motor issues or a buildup of dirt on condenser coils.
