I performed a heating maintenance on a 2016 heat pump system. I checked amps, capacitors, filter, electrical, cleanliness, and safeties. I observed several issues with the system. The indoor needs a thorough cleaning. The evaporator coil has build up present on the back side, the blower motor has build up present, and the ducts are filthy. These issues will cause damage to the blower, evaporator coil, and compressor. Dust is the number one root cause of system failure. The outdoor unit is amping high during start up, the capacitor has failed and no longer guaranteed to work, the contactor is buzzing due to bad contacts, and the condenser fan motor is amping at its maximum amps. Customer did not want options for any of the issues besides the hard start and evaporator cleaning.
