Ductless systems avoid a lot of the problems that plague more traditional heating systems. Unfortunately, they aren’t perfect. Ductless heaters still have a number of common problems of which every homeowner should be aware. Let’s take a look at some of the most common ductless heating problems that require repairs.
When a ductless heating system is installed, it is “charged” with a set amount of refrigerant. This refrigerant is what allows the ductless system to heat your home, by being evaporated to draw in heat and then condensed to expel it in another place. If a leak develops in the refrigerant line, the initial charge will drain over time until there isn’t enough to transport heat. At this point, your ductless system will be pretty much unable to do its job. If you notice liquid of any kind dripping or pooling on or under your ductless system, it’s a good idea to call a professional to take a look at it.
Broken Fan Belt
The fan belt is a rubber loop that transfers motion from the motor to the fan. Over time, wear and tear from everyday use can cause this belt to stretch and develop cracks. This deprives the belt of the elasticity it needs to operate properly. If left untreated, the fan will eventually break. With no connection between the fan and the motor, there is no way to circulate air through the room. If your ductless heater turns on but doesn’t seem to be blowing air, you may have a broken fan belt. Pay attention to the noises your unit makes, as well. A loud squealing sound on startup is an indication of a failing fan belt.
The motor is what makes the whole ductless heating system run, and is obviously a vital part. Upon occasion, the bearings inside the motor can wear down and create friction. This creates a lot of extra heat when the motor is running, and can eventually cause it to overheat. If you hear a grinding noise coming from your ductless unit, turn it off and call a professional.
