What’s the Noise Coming from My Ductless AC in Orlando, FL?

Your ductless system in Orlando, FL, should only softly hum while regulating your home’s temperatures. Any other noise from the system is a sign of trouble. If you hear any of these noises coming from your ductless system, it’s probably time to schedule a repair.

Rattling

The components of your ductless system become worn out with time. The worn-out components may become loose and produce a rattling sound as the system runs. If left unchecked, a loose component may damage other parts and pieces.

Banging

A banging sound may occur when there are loose parts in your heat pump. The loose parts collide with other components, producing this noise. The noise may also sound like metal hitting against other metal in your system.

Hissing and Bubbling Noises

Your ductless system uses a special fluid called a refrigerant to extract heat from the indoor air and transfer it to the environment. This fluid must be at a high temperature and pressure for heat transfer between the refrigerant and the environment to occur.

Perforations along the refrigerant lines can allow the fluid to escape. The fluid produces a hissing or whistling noise as it escapes because it is under high pressure.

When air bubbles enter the refrigerant lines through the tiny openings, bubbling noises occur. Schedule repair services immediately after you detect these noises, as low refrigerant levels make your ductless system overwork.

Buzzing and Continuous Clicking

You may hear a buzzing noise when your ductless system’s electrical connections have problems. On the other hand, continuous clicking sounds may be a sign of a faulty capacitor.

Addressing the noises as soon as possible prevents the underlying problem from deteriorating. Call the cooling experts at Air King whenever your ductless system produces strange noises.
