Performed AC cool check on two systems and checked the electrical, mechanical, safety, and performance of the systems. I cleared the condensation drain lines and flow tested the drains with two gallons of water. I also treated the drain lines. I treated the inside of the electrical cabinets on the condensers with JS insecticide to keep ants away from the contactors. The condenser coils were cleaned. No major issues were found. Both systems were running at the completion of service.
