I am a highly skilled home service professional who recently completed a furnace maintenance job. The job entailed a thorough inspection of the furnace, including checking the burners, ignition system, and safety controls. I also performed a maintenance checklist to ensure that all components were functioning properly. I replaced the air filter and cleaned the blower wheel and burner assembly. I also checked the thermostat and made any necessary adjustments. Finally, I tested the furnace to ensure that it was operating at peak efficiency.
