Air Conditioning System Repair: Arrived at the client’s home after they reported a strange noise coming from the air conditioning system. Inspected the outdoor unit and discovered a loose condenser fan blade causing vibration and rattling during operation. Secured and rebalanced the blade, then checked the motor and mounting hardware to ensure no additional issues were present. Tested the system afterward and confirmed smooth, quiet operation. The noise is no longer coming from the system, and the AC is running properly.
