Picked up the material from Apex Supply Sandy Springs and Johnstone Sandy Springs. Arrived at the customer’s home to complete quoted repairs. Removed the failed UV bulb for the upstairs Apco-X. Tested operation to ensure it functions properly. Open up the coil compartments for both the upstairs and main floor systems. Cleaned both coils with evaporator coil cleaner. Also treated the coils with Bio Fresh. Reported results to the customer.
