Performed AC cool check. 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 filters were clean and had been recently replaced by the tenant. I cleaned the condenser coil. The capacitor on the condenser unit was below value. Options for repair were presented to the homeowner. He chose to have the capacitor replaced today. I replaced the condenser capacitor and function tested the system. The system is operational and was running at the completion of service.
