Key takeaways
- Typical repair: $150–$600.

- Labor runs about $50–$150 per hour plus a diagnostic fee.
- A fall tune-up ($100–$200) helps prevent winter breakdowns.
Furnace repair cost by fuel type
| Furnace type | Typical repair cost |
|---|---|
| Electric | $50–$300 |
| Natural gas | $300–$1,200 |
| Propane | $300–$1,200 |
| Oil | $400–$1,500 |
Oil furnaces tend to cost the most to repair because soot buildup often means a cleaning is needed along with the repair.
Common furnace repairs
- Flame sensor cleaning or replacement: usually the low end of the range.
- Igniter replacement: a frequent cause of a furnace that won't light.
- Blower motor or capacitor: mid to high range depending on the part.
- Control board: one of the pricier repairs.
- Heat exchanger problems: often a sign it's time to price a replacement, and a safety issue because of carbon monoxide risk.
If you smell gas or your carbon monoxide alarm goes off, leave the house and call your gas utility or 911 first. Don't wait for a repair visit.
How to pay less for furnace repair
- Schedule a tune-up in early fall, before the first cold snap.
- Replace the filter regularly; a clogged filter makes furnaces overheat and shut down.
- Check the basics first: thermostat batteries, the breaker, and the furnace power switch.
- Ask if the diagnostic fee is credited toward the repair.
