Furnace repair in Oklahoma typically runs $200-$900 depending on what failed. Most common repairs (flame sensor, ignitor, capacitor) are at the low end. Heat exchanger or gas valve issues push toward replacement territory. Here is what each common repair actually costs.

Detailed Pricing Breakdown

Service / PartCost Range
Flame sensor cleaning/replacement
The most common furnace repair. A dirty sensor causes the furnace to ignite and immediately shut down.		$150-$250
Hot surface ignitor
Ignitors fail every 5-10 years from heat cycling. Quick replacement, common stock part.		$250-$400
Capacitor (blower)
Blower not spinning despite the burner igniting? Usually capacitor.		$180-$280
Inducer motor
The motor that pulls combustion gases out through the flue. Failure means the furnace won't fire at all.		$400-$700
Gas valve
Less common but serious. Gas valves are replaced rather than repaired for safety.		$500-$900
Control board
The "brain" of the furnace. Less frequent failure but expensive when it goes.		$400-$800
Blower motor
Bearing noise for weeks before complete failure. Replace before total failure to avoid emergency call.		$500-$900
Heat exchanger
A cracked heat exchanger is a safety issue and usually means replacement makes more sense than repair.		$1,500-$2,500+
Diagnostic visit
Waived if you approve the recommended repair.		$89

Frequently Asked Questions

Why does my furnace keep short-cycling?
Most common causes: dirty flame sensor (cheap fix), faulty pressure switch, overheating due to restricted airflow (dirty filter or duct blockage), or thermostat miscalibration. We diagnose the actual cause before quoting repair.
Is a cracked heat exchanger dangerous?
Yes — a cracked heat exchanger can leak carbon monoxide into your home. If we find one, we recommend immediate system shutdown and replacement. Heat exchanger replacement rarely makes economic sense on older units.
Why is my furnace making loud noises?
Rumbling: delayed ignition (dangerous — shut off and call). Squealing: blower motor bearings. Banging on startup: expanding ductwork (usually cosmetic). Whistling: air leak or filter issue. Each has different repair costs.
Can I run my furnace if it's making weird noises?
Depends on the noise. Shut it off and call us immediately if: you smell gas, you smell exhaust inside the home, or the furnace makes booming noises on startup. Non-urgent noises (squealing, rattling) can wait for scheduled service.
How much does an emergency furnace repair cost after-hours?
At ARP, emergency repairs are charged at standard rates — no weekend or after-hours surcharge. Same labor rates whether the call comes in on Monday morning or Saturday night.
