Listen for These Ductless Noises

If you’re using a ductless system to keep cool this summer, one of the things you need to do is be vigilant for any problems that may occur. The faster you can identify problems and have them repaired, the more damage to your system you can prevent. So, make sure that you know the signs that your system is in trouble. One of the best ways to tell is by listening for strange noises. Read on to find out about some of the strange ductless noises that indicate a problem.


Hissing and gurgling sounds indicate that air bubbles have formed in your ductless system’s refrigerant line. This means that there’s a leak somewhere in your system. Refrigerant is integral to the operation of the ductless system. Without it, the system would not be able to absorb and release heat in order to cool your home. So, a refrigerant leak is a serious threat to the health of your ductless mini split.


Each air handler that your ductless mini split uses is outfitted with a series of oiled bearings. These are designed to reduce the amount of friction on the system during operation. These bearings wear down over time, causing the friction on the air handler to increase. This will cause a loud grinding sound to come from the air handler. If you hear this sound, call for repairs before the air handler burns itself out.

Short Cycling

Short cycling is when your ductless system turns itself on and off every few minutes continuously. It could be caused by a faulty thermostat, or a problem with the compressor. What’s important, though, is that it’s a huge threat to your system. If it’s not dealt with, it could shorten the lifespan of your ductless mini split significantly.
