What furnace repair costs
Most furnace repairs run $300 to $1,200, with about $450 as a national average. The part that failed makes most of the difference.
| Repair | Range |
|---|---|
| Flame sensor | $80 to $250 |
| Igniter | $175 to $300 |
| Blower motor | $250 to $900 |
| Control board | $300 to $650 |
| Heat exchanger | $500 to $3,500 |
Repair or replace?
A common rule of thumb: multiply the repair price by the furnace's age. If the result is above about $5,000, or the furnace is past 15 years, get a replacement quote too. A cracked heat exchanger on an older furnace almost always points to replacement.
Fees to ask about
Many companies charge a service or diagnostic fee, often credited toward the repair if you go ahead. Nights, weekends and holidays usually cost more. Ask about all of it on the phone so there are no surprises.
