Customer reported unusually loud operation from their AC unit. Upon inspection, found the condenser fan motor bearings were worn and causing excessive noise. Checked blade alignment and mounting hardware — no signs of damage. Replaced the fan motor with an OEM part and verified decibel levels post-repair. Also tightened all panel screws and checked compressor isolation mounts. System is now running smoothly and much quieter. Recommended follow-up in 6 months to monitor motor performance and overall system noise.
