Was your home comfortable and cool all summer long, even when the hot weather was at its worst? You probably have your Mitsubishi Electric heat pump mini splits to thank. But just because your air conditioning system seemed to be working effortlessly doesn't mean it wasn't working hard. Just like any other HVAC system, your mini splits need regular service and repair to keep operating at their maximum efficiency.
So, with the fall bringing in relief from the heat and giving your mini splits a breather, now's the best time to schedule heat pump service to make sure your mini splits — both the indoor air handler and the outdoor condenser unit — handle the winter as well as they did in the summer.
Heat Pump Mini-Split Tune-Up Checklist
Inspecting and tuning up your mini-split system is a complex process. Yes, there are relatively straightforward fixes, such as:
Replacing your air filters to allow for proper air flow
Clearing debris around the outdoor condenser unit to clear obstructions and allow for clear drainage
But the majority of maintenance tasks should be left to an experienced contractor like Kearney. Here are just some of the areas of your heating and cooling unit we'll check in a mini-split heat pump maintenance call.
Deep cleaning your indoor and outdoor evaporator and condenser coils will help your mini split operate at its most efficient and should be at the top of any heat pump repair and maintenance checklist. Dirty indoor and outdoor coils can translate to higher energy bills, expensive repair calls, and a shortened lifespan for your heat pump system. According to a report from Southern California Edison, dirty condenser coils can reduce a unit's cooling capacity by as much as 40%.
Also important to the operation of your mini split are your refrigerant levels. The same SCE report shows that low refrigerant levels reduced cooling capacity in an HVAC system by as much as 20%. A trained service technician should be annually checking the refrigerant lines, coils, and flare connections for potential leakage.
Your heat pump's compressor circulates refrigerant between the indoor and outdoor units, which is essential to the heating and cooling process. Compression components like electronic expansion valves (EEVs), digital inverter-driven compressors, and other sensors should be inspected and tested to ensure optimum performance.
