A furnace tune-up is a yearly preventive service where a technician inspects, cleans, tests, and fine-tunes every major component on your furnace — combustion, electrical, ignition, blower, and safety systems. It restores the furnace to near-factory performance, catches worn parts early, and keeps the manufacturer’s warranty valid.
What a furnace tune-up includes
- Combustion analysis and gas pressure check
- Heat exchanger inspection for cracks (carbon monoxide safety)
- Burner, igniter, and flame sensor cleaning
- Blower motor and capacitor test
- Thermostat operation and calibration
- Filter check and replacement recommendation
- Tight electrical connections and safety switch verification
Annual tune-ups prevent the majority of mid-winter no-heat calls. Schedule one through our furnace maintenance service or join the Mainstream Maintenance Plan for spring and fall visits at a discounted rate.
