Why Furnace Maintenance Matters
- Improve reliability and reduce emergency repairs
- Lower energy usage and utility bills
- Extend equipment lifespan

- Protect your manufacturer warranty requirements
What Our Tune Up Includes
Every home is different, but a standard maintenance visit typically covers:
- Thermostat check and system test
- Inspect heat exchanger, burners, and flame sensor
- Clean burners and combustion area as needed
- Verify ignition sequence and safety controls
- Check blower wheel, motor amperage, and capacitor
- Replace standard 1 inch filter or install customer supplied filter
- Inspect flue venting and draft
- Check gas pressure and connections for leaks
- Measure temperature rise and static pressure
- Inspect condensate drain and trap on high efficiency units
- Calibrate and tighten electrical connections
- Final run test and recommendations
Tip: Pair your fall furnace maintenance with a spring AC tune up for year round comfort and consistent savings.
