Call for Repairs if Your Ductless System is Making These Noises

Heating system issues are common during the winter, when strain on them is greatest. This is especially true with heat pumps like ductless systems, which are put under more strain year-round than other climate control systems. You should be vigilant for problems that might afflict your ductless system during this time. One of the best ways to catch ductless systems early is to listen for strange noises.


Each air handler in a ductless system generates a lot of friction during operation, as it circulates air throughout the room. Oiled bearings are installed in the air handlers, in order to help them run more smoothly. Over time, these bearings will wear down and need to be replaced. As the bearings wear down, the friction on the air handler will increase. This can generate a grinding sound, in extreme circumstances. If you hear the system making this noise, call for repairs before the air handler motor burns itself out.


If you hear hissing or bubbling noises coming from your system, it could mean that air bubbles have formed in the refrigerant line. The most likely reason for that happening is a leak in the line, which will drain the system over time. This will cause a steady drop in output, followed by ever-increasing malfunctions. The ductless system will eventually break down if the leak isn’t patched, and the lost refrigerant replaced. Call for repairs if you hear this, or happen to notice fluid dripping from your system. This is one of those system issues that should never be ignored.
