We will make sure that you understand the situation with your system and we will discuss all the options with you so that you can make the best decision regarding your heating or cooling.


Improving Heating Function in Cold Climates
When running your mini split for heating purposes, it’s normal for frost to build up on the outdoor coil. In order to remove the frost and maintain optimal performance of the mini split, the condenser must periodically switch to a defrost mode. 

As the frost melts, it drips into a drain pan. In extremely cold conditions, the dripping water may freeze before it has a chance to escape the drain pan. Over time, the buildup of ice can get thick enough to freeze the fan blades to the pan. Another problem that can occur is frozen water getting between the fins of the coil, expanding, and cracking the coil.

Repairs associated with ice build-up in a drain pan can cost a lot, to prevent this kind of damage, it is strongly recommended to use a drain pan heater when using a mini split for heating in areas that experience subfreezing temperatures.

A drain pan heater rests in the drain pan and plugs directly into the control board of the outdoor condenser. The control board signals the heater to turn on automatically in conditions where freezing is likely. This prevents water from freezing in the drain pan and protects the condenser from damage. Just keep in mind that drain pan heaters are specific to both brand and condenser model.
