How much does furnace tune-up cost?
A furnace tune-up gets your heating ready before cold weather. A tech cleans and checks the burners, flame sensor and igniter, tests safety controls and looks at the venting. Like an AC tune-up, it takes about an hour, so most of the price is the visit itself.

What's usually included
- Burners and flame sensor cleaned
- Igniter and gas pressure checked
- Safety limits and rollout switches tested
- Flue and venting checked for blockage, with a carbon monoxide check
- Blower motor and belt checked, and the filter looked at
- Thermostat tested through a full heating cycle
What changes the price
- Number of systems. Two furnaces mean two tune-ups.
- Furnace type. High-efficiency furnaces have extra parts, like a condensate drain and inducer motor, that take more time.
- Timing. Fall visits are easier to book. The first cold snap brings a rush, and after-hours calls cost more.
- Parts. A worn flame sensor, igniter or blower part found during the visit costs extra.
Do it yourself or hire a pro?
Changing the filter and keeping the area around the furnace clear are easy jobs for anyone. Cleaning burners, testing safety switches and checking for carbon monoxide involve gas and combustion, so hire a qualified tech for the tune-up itself. Make sure you have working carbon monoxide alarms either way.
Common questions
How often should a furnace be serviced?
Once a year is the common guideline, usually in the fall. Check your furnace warranty, since some require yearly service.
Do electric furnaces need tune-ups too?
They need less work since there is no gas burner, but a check of the heating elements, wiring and blower is still a good idea.
What if the tech says my heat exchanger is cracked?
A cracked heat exchanger can be a real safety problem, but it is also a costly claim. Ask to see photos or the crack itself, and get a second opinion before replacing the furnace.
