Most furnace repairs run $133–$505, with an average of $318 per job (HomeAdvisor) — and the extended band runs $64–$1,475 from a sensor clean to a multi-part repair. A service call alone is $50–$200, and emergency no-heat calls bill $140–$210/hr. Every band below comes from a cited cost guide — nothing here is our estimate.

Common repairs by part

Part / service	Band	Notes
Diagnostic / service call	$50–$200	HomeAdvisor labor $50–$150/hr plus a trip fee; Thumbtack flat service fee averages ~$69; Bob Vila advanced inspection $130–$200.
Igniter (hot-surface)	$150–$500	HomeAdvisor part+install band; the most common no-heat part failure.
Flame sensor	$150–$250	HomeAdvisor; often a clean-instead-of-replace fix.
Capacitor	$179–$250	Thumbtack; a stalled or humming blower is the usual symptom.
Control / circuit board	$200–$1,000	HomeAdvisor part $200–$600; Thumbtack full replacement $600–$1,000.
Gas valve	$200–$600	HomeAdvisor; igniter glows but burners never fire.
Draft inducer motor	$200–$1,500	HomeAdvisor; loud whine or rattle at startup.
Blower motor	$150–$2,000	HomeAdvisor part band $150–$2,000; Thumbtack splits single-speed $400–$600 vs variable-speed $600–$1,300.
Heat exchanger	$100–$1,500	HomeAdvisor part band; a crack is a carbon-monoxide hazard (Bob Vila) and frequently tips the repair-vs-replace decision.

Labor rates

What moves the price

Fuel type: HomeAdvisor: electric furnaces are often cheaper to fix; gas, propane, and oil repairs run higher.
Furnace age: Older units with out-of-date boards or hard-to-find parts raise the bill — some vintage models can't take new parts at all (HomeAdvisor).
Warranty: If the furnace is new or under warranty and needs a small part (e.g., a dirty flame sensor), repair is almost always cheaper; once an older, less-efficient unit starts racking up repair bills, replacement looks smarter (HomeAdvisor).
Repair-vs-replace: If required furnace repairs equal more than 30% of the cost of a new furnace, replacing is often the better investment (Bob Vila). Replacement bands start at $1,600 for electric swaps (see our furnace replacement guide).

FAQ

How much does it cost to repair a furnace?

Most furnace repairs land between $133 and $505 with an average of $318 (HomeAdvisor); Thumbtack's national band is $170–$735 (most ~$352) and Bob Vila cites $100–$600. Small fixes like a flame-sensor clean sit near the low end; a blower-motor or heat-exchanger job pushes toward the top.

Do furnace repair companies charge a service call fee?

Yes — expect roughly $50–$200: HomeAdvisor lists labor at $50–$150/hr plus a trip fee, Thumbtack's flat service fee averages about $69, and Bob Vila's advanced-inspection band is $130–$200.

When should I replace the furnace instead of repairing it?

HomeAdvisor's rule of thumb: a new or in-warranty furnace needing a small part is almost always worth repairing, while an older unit racking up repeated repair bills points to replacement. Bob Vila adds a threshold: if the required repairs exceed 30% of a new furnace's cost, replacement usually wins.

How much is emergency furnace repair?

Emergency or after-hours rates run $140–$210 per hour versus $50–$150 standard (HomeAdvisor and Bob Vila) — roughly double for a no-heat call on a weekend or holiday.
