I performed a comprehensive maintenance service on a 10-year-old split Lennox furnace. This involved a thorough inspection of all components, including the burners, heat exchanger, and blower motor. I cleaned and adjusted the burners to ensure optimal performance and efficiency. Additionally, I checked the heat exchanger for any signs of wear or damage and cleaned the blower motor to remove any accumulated dust or debris. I also inspected and cleaned the air filters, ensuring they were free from obstructions. Finally, I tested the thermostat and control settings to confirm everything was functioning correctly.
