Performed AC cool check and checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. I also treated the drain line. Air filters were replaced with client supplied filters. I cleaned the condenser coil. I found the condenser fan motor showed signs of overheating. Options for repair were presented to the homeowner and he chose to have the condenser fan motor replaced and to install surge protectors on the furnace and condenser unit. I replaced the condenser fan motor and installed surge protectors on the furnace and condenser unit. I function tested the system and the system was operational. No other issues were found. The system was running at the completion of service.
