AC Repair Service: A troubled homeowner reached out concerning an uncommon noise from their AC system. To diagnose this issue, I conducted a thorough system evaluation. During the inspection, I determined that the source of the noise was a loose fan blade. I secured the fan blade, and after the adjustment, I confirmed that the AC system was running smoothly and quietly, effectively resolving the noise problem while ensuring optimal performance. Following the system's confirmation of top-notch performance, I explained to the homeowner the benefits of our maintenance plans to maintain this level of excellence.
