HVAC ignitor replacement typically costs $150-$400 for a residential gas furnace, with many homeowners paying about $250. The final price depends on the ignitor type and model, local labor rates, diagnostic fees, and whether the repair happens during regular business hours.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete ignitor replacement | $150 | $250 | $400 | Common residential repair |
| Replacement ignitor part | $25 | $55 | $100 | Model and design affect price |
| Diagnostic or service call | $75 | $110 | $175 | May be credited toward repair |
| After-hours replacement | $250 | $400 | $600 | Urgent nights, weekends, or holidays |
Furnace ignitor replacement usually costs $150-$400
A standard repair usually includes troubleshooting, a compatible ignitor, installation, and a test cycle. The average assumes a common gas furnace, normal access, and daytime service in a mid-priced U.S. market. A basic silicon carbide ignitor can cost less than a less common silicon nitride or manufacturer-specific part.
For a routine residential visit, budgeting around $250 is a reasonable starting point. Quotes below $150 may exclude the diagnostic visit or reflect a low-cost part, while totals above $400 can involve a specialty component, higher labor rates, or additional work. Assumptions: standard gas furnace, weekday service, normal access, no related repairs.
What a furnace ignitor repair quote includes
Contractors may list the diagnostic visit and repair as separate charges or combine them into one flat price. Ask whether the quoted total includes testing the furnace after installation and whether the service-call fee is applied to the repair.
| Quote item | Typical price | What changes the charge |
|---|---|---|
| Ignitor part | $25-$100 | Universal versus model-specific part |
| Labor | $75-$225 | About 0.5-1.5 hours at $75-$150 per hour |
| Diagnostic or dispatch | $75-$175 | Visit policy and local minimum charge |
| Small materials and testing | $0-$40 | Connectors, wiring, or added checks |
| Disposal | $0-$25 | Often included for a small part |
The total depends on how the contractor bills the visit, not just the price of the ignitor. Some companies charge one repair price that already covers the service call; adding a separate diagnostic fee to that price could double-count the visit.
How furnace model and ignitor type shift the price
Ignitors are not interchangeable across every furnace. A common replacement may cost $25-$60, while a specialty or original-equipment part can run $60-$100 or more. Compatibility depends on the furnace model, electrical connection, shape, and manufacturer specifications.
Confirm the part number against the furnace data plate before comparing estimates. A furnace that is 15-20 years old may have a harder-to-source component, but age alone does not determine the repair price. If the ignitor is damaged by a wiring problem or another failing control, the technician should identify that issue before installing a new part.
Can cleaning or repair avoid a new ignitor?
A technician may find that the furnace will not light because of a dirty flame sensor, loose connection, faulty wiring, or another ignition-system issue rather than a failed ignitor. Cleaning or tightening a connection might cost about $100-$250, depending on the service-call fee and diagnostic time. These repairs are different from replacing a cracked or electrically failed ignitor.
Ask what test confirms the ignitor has failed before approving replacement. An ignitor that glows but does not light the burners may point to a different problem, while a cracked ignitor usually needs replacement. Avoid repeated resets or handling the part; it can be fragile, and gas-appliance diagnosis should be left to a qualified technician.
Why labor time and service-call fees vary
A straightforward job often takes 30-60 minutes once the technician has the correct part. Troubleshooting, removing panels, checking wiring, or returning with a special-order component can extend the visit to 1-1.5 hours or require a second appointment. Some contractors charge a flat repair price rather than itemizing hourly labor.
Check whether the estimate includes diagnosis, installation, and a heating-cycle test. A service-call fee of $75-$175 is common, but a company may waive or credit it when the repair is approved. Ask about the labor warranty as well; part warranties do not always cover the labor to install a replacement.
Regional furnace repair prices differ by labor market
Labor rates and service minimums vary across the United States. Prices in high-cost metro areas and parts of the Northeast or West Coast may run about 15%-30% above a mid-market estimate. Smaller cities and rural markets can be 5%-15% below it, although long travel distances may offset the savings.
Compare local estimates for the same part and included services. A $300 quote in a high-cost city may be ordinary, while the same price in a lower-cost area may warrant asking for an itemized explanation. Regional ranges are not guarantees; contractor availability, furnace access, and parts supply also matter.
When after-hours calls raise the ignitor bill
Evening, weekend, and holiday appointments can add roughly $75-$200 to a routine repair, or raise the total to $250-$600. The added charge may appear as an emergency dispatch fee, a higher labor rate, or both. A regular-hours appointment can cost less when the home can safely wait and the contractor has an opening.
Ask for the total after-hours price before authorizing dispatch. If the furnace is not operating in freezing weather, prioritize safe temporary steps and prompt professional help rather than repeatedly restarting it. Do not use an oven or outdoor heater to warm the home.
Three furnace ignitor quotes for different repair scopes
A basic quote might cover a common part and a short daytime visit. A mid-range quote may include a higher-priced manufacturer-specific ignitor and more diagnosis. A high quote can reflect a specialty part, expensive local labor, or urgent service; it should identify those conditions clearly.
| Example | Scope and labor | Estimated total |
|---|---|---|
| Basic weekday repair | $35 part, 0.5 hour labor at $90, $75 visit | $155-$210 |
| Model-specific replacement | $70 part, 1 hour labor at $125, $100 visit | $250-$325 |
| Urgent specialty repair | $100 part, 1.5 hours labor at $150, $150 dispatch premium | $425-$600 |
Use these examples as quote comparisons, not fixed local prices. Before accepting an estimate, verify that it names the furnace-compatible part, includes any dispatch charge, and explains whether additional repairs require separate approval.
