How Much Does Furnace Repair Cost?
Real 2026 pricing for gas, electric, oil, and propane furnaces - by part, by fuel type, and by emergency call. What to pay, what drives the bill, and when to call now versus wait until morning.
Last updated: July 2026
This content covers general cost ranges only. Gas appliance repair involves risk of gas leaks, carbon monoxide, and fire — always use a licensed HVAC technician or plumber, and never attempt gas line or pilot light repairs yourself if you smell gas or are unsure.
No heat right now?If it's a gas furnace and you smell gas or see a yellow/flickering pilot light, shut it off, leave the house, and call your gas utility or 911 first. If there's no gas leak and temperatures indoors are safe, call 2-3 local HVAC companies and ask for their emergency call-out fee upfront - most quote a flat $250-$500 minimum for after-hours visits. Waiting until business hours tomorrow typically saves $100-$300.
The Short Answer
Furnace repair costs $133 to $505 on average in 2026, with most homeowners paying around $318 for a single visit. The biggest cost driver is which part failed - a flame sensor runs $150-$250 while a heat exchanger can hit $1,500 and often means replacement time. Gas, propane, and oil furnaces typically cost more to fix than electric models because of specialty burners, igniters, and heat exchangers. Labor runs $50-$150 per hour plus a trip fee, and after-hours emergency calls add a $100-$300 premium. Regional labor rates can swing the total ±40%.
Furnace Repair Cost by Part (2026)
The failed part is the single biggest cost driver. Here's what each common furnace component costs to replace, including parts and labor.
| Part | Typical Cost | Repair Time |
|---|---|---|
| Flame sensor (clean/replace) | $150-$250 | 30-60 min |
| Ignitor (hot surface or pilot) | $150-$500 | 45-90 min |
| Thermostat | $100-$600 | 60-120 min |
| Control / circuit board | $200-$600 | 60-120 min |
| Gas valve | $200-$500 | 60-120 min |
| Pilot light / thermocouple | $150-$300 | 45-90 min |
| Capacitor (blower motor start) | $100-$300 | 30-60 min |
| Blower motor | $150-$2,000 | 90-180 min |
| Heat exchanger | $100-$1,500 | 4-8 hrs (often = replace furnace) |
| Air filter (DIY or service call) | $20-$100 | 10-30 min |

Furnace Repair Cost by Fuel Type (2026)
Electric furnaces usually cost less to fix because they have no burners, gas valves, or heat exchangers. Gas, propane, and oil furnaces share many parts but oil units need extra components (oil pump, nozzle, filter) and fewer techs work on them.
| Furnace Type | Typical Repair Range | What Drives the Cost |
|---|---|---|
| Electric furnace | $100-$300 | Simpler parts (heating elements, sequencer, blower). No gas components. |
| Gas furnace | $150-$500 | Most common. Ignitor, flame sensor, gas valve, heat exchanger failures. |
| Propane furnace | $150-$500 | Shares gas furnace parts; propane orifice and regulator differ. |
| Oil furnace | $200-$600 | Oil pump, nozzle, filter, heat exchanger. Fewer techs = higher labor. |
Typical repair ranges by fuel type; actual cost depends on the failed part. Based on HomeAdvisor 2026 + Angi 2026 furnace repair data. Fuel-type ranges reflect part cost differences - a blower motor costs roughly the same across all four types.
Emergency & After-Hours Furnace Repair Pricing
When you call matters almost as much as what broke. Here's how timing changes the bill - the detail most cost guides bury or skip entirely.
| Call Timing | Premium | What You're Paying |
|---|---|---|
| Business hours, scheduled | No premium | Standard $50-$150/hr labor + trip fee. |
| Same-day, business hours | Usually none | Priority scheduling, standard rates. Best value for urgent-not-emergency. |
| After-hours / overnight (6pm-7am) | +$100-$250 | 1.5x-2x labor rate + emergency trip fee $75-$200. |
| Weekend call | +$150-$300 | Higher than weekday after-hours; limited crew on. |
| Holiday (Thanksgiving, Christmas) | +$200-$400 | Highest tier. Some companies refuse non-no-heat calls. |
| 24/7 flat-rate emergency | $250-$500 min | Some companies bill a flat emergency minimum regardless of repair. |
Premium ranges based on HomeAdvisor 2026 HVAC labor data + industry after-hours pricing patterns. Exact surcharge varies by company and market.

5 Factors That Change Your Furnace Repair Cost
1. Which part failed (the biggest driver)
A flame sensor cleaning is $150-$250 and takes an hour. A heat exchanger can run $1,000-$1,500 and takes 4-8 hours - on a furnace over 12-15 years old, that quote usually means it's replacement time. Get the tech to show you the failed part and explain why it failed before approving any $500+ repair.
2. Fuel type
Electric furnaces are simplest and cheapest to fix ($100-$300) - no burners, no gas valve, no heat exchanger cracking risk. Gas and propane furnaces share most parts ($150-$500 typical). Oil furnaces cost the most ($200-$600) because of the oil pump, nozzle, and filter - and fewer techs work on them, which pushes labor rates up.
3. Furnace age and parts availability
A furnace under 10 years old usually has parts in the tech's truck - same-day fix. A 15-20 year old furnace may need parts ordered, leaving you without heat for 2-5 days during peak winter. Some older brands (York, Heil, older Carrier units) have discontinued parts that force a full replacement even for a minor failure.
4. Emergency timing
The same flame sensor repair costs $200 on a Tuesday afternoon and $450 on a Saturday night. If indoor temps are above 50°F and you have a safe backup (space heater, fireplace), waiting until morning is the single biggest cost saver - typically $100-$300 less. Below 50°F with kids, elderly, or medical needs, the premium is worth it.
5. Brand and warranty status
Major brands (Trane, Carrier, Lennox, Goodman, Rheem, Bryant, American Standard) have widely available parts. Check your warranty first - many furnaces have 10-20 year part warranties on the heat exchanger, and the original install may still be covered. A warranty-covered part still costs labor ($100-$200) but eliminates the parts charge, often the bigger half of the bill.
Red Flags When Calling Furnace Repair
- Won't quote a trip fee over the phone: Reputable HVAC companies tell you their minimum service-call charge upfront ("$89-$150 trip fee, credited toward repair"). Vague answers mean a surprise invoice later.
- Quoting $1,000+ before diagnosing: Most furnace repairs land under $500. A phone quote over $1,000 without seeing the unit is a red flag - they're betting you're cold and desperate. Get a diagnostic visit first.
- Pushing full furnace replacement on a minor fix: A flame sensor or ignitor failure does not mean the furnace is dead. Some techs upsell a $4,000 replacement when a $200 part would restore heat. If the furnace is under 12 years old, get a second opinion before replacing.
- Cash-only or no written invoice: Licensed HVAC contractors take cards and provide itemized invoices with parts, labor, and warranty terms. Cash-only with no receipt is a sign of an unlicensed operator - and any warranty claim becomes impossible.
- No HVAC license or permit: Most states require an HVAC license for furnace work, especially gas furnaces. Ask for the license number and verify online. Unlicensed gas furnace work can void your homeowners insurance and create carbon monoxide risk.
- "Lifetime warranty" parts upsell: Standard furnace parts carry 1-10 year warranties. A "lifetime" part for double the price is usually a marketing label. Ask for the specific part brand, model, and manufacturer warranty in writing instead.

Frequently Asked Questions
How much does furnace repair cost?
Furnace repair costs $133 to $505 on average in 2026, with most homeowners paying around $318 for a single repair visit. Minor fixes like a flame sensor cleaning or thermostat replacement run $150-$250, while major repairs like a blower motor or heat exchanger push $500-$2,000. The overall professional range spans $64 to $1,475 depending on the failed part, furnace type, and whether you need after-hours service. Labor runs $50-$150 per hour plus a trip fee equal to at least one hour.
How much does gas furnace repair cost?
Gas furnace repair costs $150 to $500 on average, with gas, propane, and oil units typically running higher than electric models because of specialty parts like igniters, flame sensors, gas valves, and heat exchangers. A gas furnace flame sensor runs $150-$250, an ignitor $150-$500, and a heat exchanger $100-$1,500 (often signaling replacement time). Gas furnaces also require a licensed HVAC tech or plumber - gas line and pilot light work carries carbon monoxide and fire risk. Electric furnaces usually cost less to fix ($100-$300) since they lack burners and gas components.
How much is emergency furnace repair?
Emergency furnace repair adds a $100-$300 premium on top of the normal repair cost for after-hours, weekend, or holiday calls. Most HVAC companies charge 1.5x-2x their standard labor rate ($90-$150/hr vs $50-$90/hr during business hours) plus a flat emergency trip fee of $75-$200. Holiday calls (Thanksgiving, Christmas Eve) are the most expensive at $200-$400 over a weekday repair. Same-day service during normal business hours usually carries no premium - just priority scheduling. If you have auxiliary heat (space heaters, fireplace) and temperatures are safe, waiting until morning saves $100-$300.
Is it worth repairing a furnace or should I replace it?
Use the 50% rule: if the repair quote exceeds 50% of a new furnace's cost ($2,500-$6,500 installed), replacement is usually the better long-term call. Furnaces last 15-20 years with maintenance; if yours is over 12-15 years old and needs a major repair (heat exchanger $1,000+, blower motor $1,000+), the next failure is often months away. Minor repairs on a furnace under 10 years old - flame sensor, ignitor, capacitor, thermostat - are almost always worth fixing. A mid-life furnace (8-12 years) with a $300-$500 repair is a coin flip; get the tech's honest read on remaining component life before deciding.
How long does furnace repair take?
Most furnace repairs take 45 minutes to 2 hours once the technician diagnoses the problem. Flame sensor cleaning or replacement: 30-60 minutes. Ignitor swap: 45-90 minutes. Thermostat replacement: 60-120 minutes. Blower motor replacement: 90-180 minutes. Heat exchanger replacement: 4-8 hours and often not worth it on an older furnace. Diagnostic time adds 15-30 minutes upfront. Emergency response time is typically 1-4 hours in metro areas and 4-8 hours in rural areas during peak winter demand.
Does homeowners insurance cover furnace repair?
Usually no - standard homeowners insurance covers furnace damage only if caused by a covered peril (fire, lightning, falling object, sudden water damage from a burst pipe). Normal wear and tear, age-related part failure, lack of maintenance, and mechanical breakdown are excluded. If your furnace was damaged by a power surge, a frozen-and-burst pipe, or a house fire, the repair or replacement may be covered minus your deductible ($500-$2,500). Many furnace repairs ($150-$500) fall below a typical deductible anyway. A home warranty (separate policy, $300-$600/year) is what covers mechanical breakdown of an aging furnace.
What are the signs your furnace is going out?
The top warning signs a furnace is failing: (1) uneven heating - some rooms cold, others hot; (2) unusual noises - rattling, banging, or squealing from the blower or heat exchanger; (3) yellow or flickering pilot light instead of steady blue (carbon monoxide risk on gas furnaces - call a pro immediately); (4) rising gas or electric bills without rate changes, meaning efficiency is dropping; (5) frequent cycling on and off; (6) air that feels cool or lukewarm at the registers; (7) furnace over 15 years old needing its second major repair in two seasons. Any yellow flame or soot smell on a gas furnace is an emergency - shut it off and call a licensed HVAC tech.
