Call for Repairs if your Ductless System Is Making These Noises

Everyone has had that moment where an appliance starts to make a weird noise, and we just ignore it. “It’s fine, it’ll go away” we think. Except it doesn’t. It’s a problem, and we all know it, and the same is true for ductless systems. If you’ve had your ductless system for a while, you probably know what it sounds like when it’s operating. If it starts to make weird noises while it’s on, do not ignore it. Strange noises are a primary indicator that something is wrong with thesystem, possibly something seriously wrong. Read on to find out more about odd noises that indicate a problem.


Both hissing and gurgling noises indicate that there are air bubbles in the refrigerant line. This means that there’s a leak somewhere in the line, which is draining fluid from the system. Refrigerant leaks will reduce the output of the system over time, eventually culminating in a full breakdown. You should call for repairs immediately if you notice this happening.


Ductless systems use individual air handlers to circulate air throughout the rooms they service. If your air handler is making a grinding noise while the system is operating, it means that the friction on the system is much higher than it should be. Chances are, the oiled bearings in the air handler are worn down. If they’re not replaced, the motor could overheat and burn out. Have a professional look at your system before that happens, since it’s much cheaper to replace the bearings than to replace the entire air handler motor.
