Why Is My Ductless Heating and AC System So Loud?

One of the most appealing aspects of ductless HVAC is its ability to heat and cool your Deerfield, IL, home in near silence. If you notice strange noises coming from your system, something is probably wrong. Learn more about some possible ductless heating and air conditioning noises and what they mean for your mini-split.

Hissing or Gurgling

If your mini-split begins making hissing or gurgling noises, you probably have a refrigerant leak. Since refrigerant is toxic, you may need to leave your home until you can have a professional service technician fix the problem.

Your system relies on a network of tiny tubes that move refrigerant to heat and cool your air. Even a small puncture in one of those lines can result in a refrigerant leak, so you need to keep your ears open for signs of trouble.

Banging or Rattling

Dirt, pebbles, leaves, twigs and other debris can all accidentally get into your system, begin tumbling around and interfere with its workings. If some bolts or a panel door come loose, they may also begin producing banging or rattling sounds.

Fortunately, HVAC maintenance service technicians can eliminate these noises, no matter their ultimate sources. They’ll clean out debris, secure loose components and perform more extensive repairs if necessary.

Screeching or Squealing

This noise typically indicates that something has gone wrong with your system’s fan motor, bearings or fan belt. Perhaps the belt has come loose, or the motor’s interior parts have begun to grind up against one another. The almost surefire remedy for this issue is either to apply lubricant to the bearings or replace the belt.
