What’s That Sound Coming From My Ductless Mini-Split?

August 10, 2023

Ductless mini-split systems are popular for their energy efficiency and flexibility in heating and cooling individual rooms or zones in homes and buildings around Palm Coast, FL. Like any mechanical system, though, they can make noises that are unusual. Read on for information on some common ductless mini-split noises.

Vibrating

Loose panels or components within the air handler or condenser can cause this noise. Over time, vibrations from the compressor or fan may cause screws or bolts to loosen, resulting in a buzzing sound.

Gurgling

Gurgling noises may be a sign of refrigerant flow issues. It could indicate a leak or improper refrigerant charge. Refrigerant leaks can be hazardous to your health and the environment, so contacting us for air conditioning repairs is crucial.

Swooshing

A swooshing sound often occurs when refrigerant circulates through the system. This noise is typically normal and nothing to worry about. However, if the system’s cooling or heating performance reduces significantly, it may indicate low refrigerant levels.

Squealing

A high-pitched squealing or screeching sound often indicates an issue with the fan motor or blades. A lack of lubrication, worn-out bearings or misaligned components might cause this noise.

Dripping

A water-dripping sound may not necessarily be an issue. During the cooling process, condensation occurs, which usually drains away efficiently. However, if the dripping sound is loud or continuous, it could be due to a clogged drain line or a malfunctioning condensate pump.
