HVAC Repair Service: A homeowner reported smoke coming from their HVAC system during operation. Upon inspection, we discovered a burned-out blower motor and accumulated dust on the heat exchanger as the source of the smoke. Replaced the faulty blower motor, cleaned the heat exchanger and ductwork, and tested the system for safe operation. The HVAC now runs safely and efficiently, eliminating smoke and restoring clean airflow throughout the home.
