The customer scheduled their annual AC maintenance to ensure their system was running at peak performance for the upcoming summer. During the inspection, I found that the system had some dirt buildup on the evaporator coil and the drain line was slightly clogged, which could have led to water damage over time. I cleaned the coils, cleared the drain line, checked the refrigerant levels, and lubricated moving parts to prevent future wear and tear. After completing the service, the system was running smoothly, ensuring the customer’s AC would provide efficient, reliable cooling all season long.
