All wiring is tight and good condition. The coils are clean. I rinsed the condenser coil. The batteries were bad in the remote. The batteries were replaced. Tested operation. The remote is working in all functions. The system is working properly in cooling and heating. The customer is considering having the heat pump in the main house be inspected. I prepared options and an updated maintenance program for two systems. She’s going to review it but declined at this time.
