Fall Furnace Tune-Up: What We Check and Why It Matters
The furnace runs 2,000+ hours in a Minnesota winter. A fall furnace tune-up is a safety inspection first and an efficiency service second.
Safety
- Heat exchanger inspection for cracks (the source of carbon monoxide leaks)
- Carbon monoxide test at the registers
- Gas pressure and gas valve operation
- Venting, intake and exhaust inspection
- Limit and rollout switch test
Reliability
- Clean burners and flame sensor
- Test ignitor resistance
- Inducer and blower motor amperage
- Capacitor test
- Condensate trap and drain flush on high-efficiency units
- Control board and wiring check
Efficiency and comfort
- Filter change
- Blower wheel cleaning if needed
- Temperature rise measurement
- Thermostat calibration
The tune-up also keeps most manufacturer warranties valid. Book in September or October in Minneapolis, Saint Paul, Burnsville, Coon Rapids or anywhere in Minnesota.
