What’s Causing These 4 Ductless AC Noises in Durham, NC?

The ductless air conditioner in your Durham, NC, home is usually quiet during operation. It might make a slight noise but nothing that’s out of the ordinary. However, if you hear any of these four ductless AC noises, you might have cause for concern:

Hissing

A hissing sound could mean your ductless AC system is leaking refrigerant. The air conditioner needs refrigerant for the cooling process to work properly. If the refrigerant is leaking, you might notice that your air isn’t as cool as usual.

Clicking

You might hear a slight click when your air conditioner turns on or off, and that’s normal. But if the clicking is constant, it could mean a problem with the ductless AC system’s electrical parts. Some possible reasons could include a failing thermostat or a problem with the system’s controls.

Banging

A banging or thumping noise can mean there’s something loose inside the ductless air conditioner. For example, a loose fan blade or a motor part can cause this noise as it bumps against the inside of the appliance.

Getting a maintenance check can let you know if something is loose. This is a good idea because this problem can cause wear and tear on your system.

Buzzing

A buzzing sound is usually the result of an electrical issue. Something like a loose wire or a problem with the compressor can cause this noise. Electrical problems are potential fire hazards that can lead to a loss of power or even damage your ductless AC system.

If your ductless AC system is making any of the noises mentioned above, it’s best to have an HVAC professional take a look at it right away.
