I performed a single system cooling maintenance on a 2016 Heat pump system. I checked amps, capacitor, filter, drains, electrical, safeties, cleanliness. The system is cooling good with some suggested actions. I noticed that the indoor equipment and ducts are fairly dirty. The evaporator coil has dust build up, the blower motor has growth all over it. This leads to poor air quality and added stress on the system. The emergency drain pan 32x62 has a large amount of rust present. It is recommended to replace before the pan begins to leak to reduce the chance of water damage to the home. The compressor’s starting amps are on the higher side. This can result in permanent damage to the compressor and premature failure. I provided options to address these concerns.
