3 Ductless Problems You Should Know About

ductlessDuctless mini splits have a lot of advantages over other climate control systems, which is why they’re experiencing a rise in popularity across the country. However, they are just as prone to developing issues over time as any other heater or air conditioner. As you start to rely on your ductless system more and more often this summer season, it’s important that you be able to tell when your system is in need of repairs. The faster you can recognize that your ductless system is experiencing problems, the faster you can get it repaired and the more damage you can prevent.

Refrigerant Leaks

Like most air conditioning systems, your ductless mini split relies on refrigerant to cool your home. The system evaporates refrigerant inside to absorb heat, then condenses it back into liquid outside to vent the heat it collected. Ductless systems do not consume refrigerant and rely on having the same charge of refrigerant throughout their lifespans. If a leak develops in the refrigerant line, the output of the system will drop as the refrigerant does. Eventually, this will cause a full-system breakdown.

Air Handler Failure

Each air handler in the ductless system contains a number of bearings, designed to help it run more smoothly and reduce friction. As the bearings wear down over time, the friction on the air handler will begin to increase. If you hear a grinding sound coming from any of your ductless air handlers, call for repairs right away. The bearings will likely need to be replaced, before the air handler motor overheats and burns out.

Short Cycling

Short cycling is when your ductless system begins to turn itself on and off every couple of minutes. This is often due to an electrical problem in the system. Short cycling increases the wear and tear on the system significantly, and can shorten its lifespan if it isn’t repaired. Make sure you have a professional examine your system if it’s short cycling.
