The customer scheduled a furnace tune-up to ensure their system was ready for the colder months. During the inspection, I discovered that the burner assembly had some minor debris buildup, and the pilot light was flickering, which could cause inefficient heating. I cleaned the burner components, adjusted the pilot light, checked the thermostat calibration, and ensured the furnace's airflow was unobstructed. After completing the tune-up, the furnace was running smoothly, providing efficient heating and helping the customer avoid potential breakdowns during the winter season.
