Performed maintenance on 2 heat pump systems and 1 mini split system. Replaced customer provided 16x20x5 filters. Checked all components and refrigerant to both systems. Upstairs system is working properly and efficiently. The main floor system has a bad outdoor fan motor and is ordered from apex. I have the main floor thermostat set to emergency heat to have some sort of heat until fan motor is replaced, will need to switch it back to normal heating. Mini split system now has clean washable filters and is operating properly.
