What Causes These Common Ductless HVAC Noises in St. Cloud, FL?

Ductless HVAC systems are normally pretty quiet, so if you hear lots of odd noises, this is something you should investigate. Here are some common ductless HVAC noises in St. Cloud, FL.

1. Buzzing

Buzzing sometimes indicates that a component is loose and hitting against something. Often, it’s the fan, but it can also signal issues with the motor, condenser coils, or the electrical system.

2. Squealing

Squealing is typically a warning sign that moving components are becoming worn out. Things like the motor or belt can expand as strain on them builds. Always tackle mechanical problems sooner rather than later because you’ll save money on the extra repairs a breakdown would cause.

3. Grinding

Over time, the bearings inside a ductless system lose lubrication. This results in loud grinding sounds due to the excess friction that occurs on the bearings. The air handler will stop working eventually without proper ball bearings, so timely maintenance is essential.

4. Hissing

A consistent hissing sound likely means that refrigerant is leaking out somewhere. You may notice a strange smell like ether in the house, too. If you have a refrigerant leak, you’ll need to have call a professional perform the repairs.
