I operated the unit on heat and auxiliary heat stages. Electric back up heat strips energized as designed. The refrigerant pressures were within normal range and the defrost cycle was forced and it completed. I checked the electrical wiring and electrical systems, the run capacitor for the outdoor fan motor has dropped below specification and should be replaced. I also recommend adding a hard start kit to the compressor circuit. I spoke with the customer about both these items and prepared estimates. Other than these minor repairs the unit is operating normal. Customer signed up for a service membership.
