Annual Furnace Maintenance: Arrived on-site to service the home’s furnace and ensure optimal performance. Powered down the system and inspected the burners, heat exchanger, blower motor, and ventilation for signs of dirt, wear, or obstruction. Cleaned critical components, lubricated moving parts, and replaced the air filter. Checked all safety controls and tested system startup and airflow. After completing the inspection and adjustments, the furnace was restored to efficient, reliable, and safe operation.
