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. The air filter was replaced with a client supplied filter. I treated the inside of the electrical cabinet on the condenser with JS insecticide to keep ants away from the contactor. I cleaned the condenser coil. No major issues were found. The system was running at the completion of service.
