I arrived to find the system on and running. I made sure to rinse off the outdoor unit. I checked over the unit and found everything to be in great shape. The UV light and surge protectors are on and functional. The ICM outside is on and working properly. I tested defrost and found it to be functional on the system. Everything is working and the homeowner is very pleased with the system and how it performs. System is in working order at completion of appointment.
