Most homeowners pay somewhere between $100 and $425 to have a furnace ignitor replaced by a professional, and the part itself is only $15 to $100 of that. The spread comes from who prices the job, what the technician finds when they open the furnace, and whether you call during business hours or at 9 p.m. on a cold night. This guide lays out the published ranges, compares your realistic options side by side, and explains when an ignitor repair is a good spend and when it is a sign to look at the whole furnace.
TL;DR
- A professionally installed ignitor typically runs $100 to $425 depending on the source, the furnace and the time of the call. The part alone is usually $15 to $100.
- The labor, diagnosis and testing are what you pay for. A tech confirms the ignitor is really the problem, installs it correctly and checks that the burners light and the furnace heats.
- Emergency and after-hours calls, hard-to-reach furnaces and wiring or bracket problems are the main reasons a bill climbs above the typical range.
- If the furnace is past 15 years old and repair quotes keep coming, price a replacement before you approve another repair.
- We do not publish a flat ignitor price, but we quote the job up front, in writing, before work starts.

What professional ignitor replacement costs
Published national guides do not agree to the dollar, and that is normal. They sample different contractors, include different things in “the job,” and update at different times. Read the ranges below as a band, not a single number.
HomeGuide puts professional ignitor replacement at $100 to $250, with a national average of $175, and notes that this includes diagnostics, materials and replacement labor. Today’s Homeowner reports a higher band of $300 to $425 for parts and labor together, with about $25 to $50 of that being the part. HVAC.com’s guide lands in between: $75 to $150 for labor and a typical installed total of $150 to $300.
Put together, a reasonable planning range for a straightforward hot surface ignitor swap on an accessible furnace is roughly $150 to $350. Under $150 is possible on a simple job with a basic part. Above $400 usually means something else is going on, such as an urgent call, a specialty furnace or a second failed component.
One detail worth understanding is what you are paying for beyond the part. According to HVAC.com, a professional replacement generally includes diagnosing the fault, installing and positioning the ignitor, testing ignition and burner operation, and verifying that the furnace heats correctly. That last step matters. A glowing ignitor that does not light the burners points to a different problem, and a technician is the person who finds it before you spend money on the wrong part.
What the ignitor part costs by itself
The ignitor is one of the cheaper parts in a furnace. HomeGuide’s breakdown shows universal hot surface ignitors at $15 to $35 and OEM or brand-name hot surface ignitors at $20 to $100, both excluding installation. Today’s Homeowner cites about $25 to $50 for a typical part.
A few real listings show how the part market works. Climate Doctors lists a Goodman B1401018 hot surface igniter at $13.55 and describes it as a silicon-carbide element with nickel-chrome lead wires, designed to reach ignition temperature within 17 seconds. Supco’s IG418 flat igniter is described as an exact-replacement silicon-carbide part, and its spec sheet lists 1,800°F minimum temperature at 98 volts and under 17 seconds to temperature at 115 volts. Those numbers are a useful reminder that an ignitor runs extremely hot and is built to a tight electrical tolerance, so matching the part to your furnace is not optional.
Universal parts can need an adapter or a different bracket, and a part that fits mechanically can still have the wrong resistance or current draw for your control board. That is one reason professionals usually carry the exact part for common furnace models rather than a one-size-fits-all substitute.
Your options compared
When a furnace stops lighting, you really have five paths. Here is how they compare on cost, what you get and who they suit.
| Option | Typical cost | What is included | Best for |
|---|---|---|---|
| Buy a universal part and install it yourself | $15 to $35 for the part | The part only, no diagnosis, no combustion check | Not recommended for gas appliances, see the safety section |
| Buy an OEM part and install it yourself | $20 to $100 for the part | The correct part, but no testing or warranty on labor | Not recommended for gas appliances, see the safety section |
| Hire a professional during business hours | About $100 to $425, depending on the source and the furnace | Diagnosis, part, installation, ignition and burner test | Most homeowners with a single failed ignitor |
| Hire a professional for an emergency or after-hours call | Can exceed the usual range | Same work, faster arrival | No heat at night, frozen pipes or vulnerable family members at home |
| Replace the furnace | $4,500 and up at our shop, see below | New equipment, installation and warranty | Older furnaces with repeated repairs |
The client-side choice for most people is the third row. It keeps cost predictable, puts a licensed person in front of a gas appliance, and keeps your manufacturer warranty intact if the furnace is still covered.
What pushes the price up or down
Diagnostic and minimum service fees
Many contractors charge a minimum service fee that covers the trip and often the first hour. HomeGuide lists minimum service fees of $75 to $200, and puts typical contractor rates at $75 to $150 per hour. Replacement labor alone commonly runs $80 to $200, per the same guide.
Diagnostic fees are set at each company’s discretion. In an HVAC.com homeowner survey in Charlotte, North Carolina, just over a third of respondents reported no diagnostic fee, and among those who were charged, 27% paid $51 to $100. Colorado Springs will not match Charlotte exactly, but the pattern holds: ask whether the diagnostic fee is credited toward the repair, and get the answer before the truck rolls.
Emergency and after-hours calls
HomeGuide lists emergency service at $140 to $210 per hour outside regular hours. HVAC.com also notes that urgent or after-hours repairs and specialty furnaces can push the total above its usual $150 to $300 range. In Colorado Springs, where a January night can drop well below freezing, a no-heat call at midnight is not a time to shop around, but it is worth knowing the premium exists. If your furnace is struggling but still running, scheduling a daytime visit is the cheaper path. Our emergency furnace repair checklist walks through what to check before you call so you do not pay for a visit that a simple fix could have avoided.
Ignitor type, wiring and brackets
HomeGuide names the main variables as universal versus OEM ignitor type, whether wiring or mounting brackets also need replacing, labor rates, furnace accessibility, metro versus rural location and emergency scheduling. A furnace in a cramped attic or a tight closet takes longer to open and reassemble. A corroded connector or a cracked bracket adds parts and time.
Furnace design
Hot surface ignitors are common, but some furnaces use spark ignition or older designs. Carrier notes that a clicking sound can mean a spark-ignition system is attempting to light the fuel. Different systems mean different parts and sometimes different labor, so the first step in any honest quote is identifying what your furnace actually uses.
How to tell the ignitor is the problem
Carrier lists the usual signs: no heat, a furnace that short-cycles, no orange glow from a hot surface ignitor when the furnace calls for heat, or repeated clicking on a spark-ignition system. None of these proves the ignitor is at fault on its own. A dirty filter, a tripped switch or a thermostat issue can produce similar symptoms, and the cheapest no-heat fix really is often a clogged filter. Check the filter, the thermostat setting and the furnace switch first.
As for lifespan, Carrier does not give a universal replacement interval, and that is consistent with what technicians see in the field. Ignitors are fragile, they cycle on and off thousands of times a season, and they wear differently depending on how often the furnace runs, the quality of the part and how the installer handled it. A new ignitor that fails quickly is often a sign it was touched or installed badly.
If you see the ignitor glowing but the burners never light, or the furnace lights and then shuts off, that points beyond the ignitor. It could be a gas valve, a flame sensor or a control board issue, and that is where a diagnosis earns its fee. Our guide to furnace repair costs by problem shows what those other repairs typically involve.
Can you replace the ignitor yourself?
You will find DIY videos and cheap parts everywhere. The part is cheap, but the job is not risk-free, and here is where we want to be direct.
Carrier recommends professional service because ignitors are delicate and high-voltage, and an incorrect installation can cause immediate failure or safety risks. Carrier also notes that improper installation by non-professionals poses risks including gas leaks, high-voltage electrical hazards and carbon monoxide exposure. A hot surface ignitor can crack from the oils on your fingertips or from a slight bump, and a replacement that is mispositioned can fail to light the burners or light them late.
There is a warranty angle too. Carrier states that third-party or non-authorized parts can void the original manufacturer’s warranty, and it advises homeowners to insist on Factory Authorized Parts to preserve warranty coverage, original efficiency and engineered safety standards. If your furnace is still under a parts warranty, the right sequence is to call a professional who can use the correct part and document the repair.
If you smell gas at any point, leave the home, do not touch switches, and call your gas utility or 911 from outside. In Colorado Springs that means Colorado Springs Utilities. A carbon monoxide alarm that sounds is also a reason to leave and call for help, not to troubleshoot.
For these reasons, we treat ignitor replacement as a professional job. The money you might save on labor is small compared with the cost of a wrong part, a voided warranty or a safety problem with a gas appliance.
What we see in Colorado Springs furnaces
A failed ignitor is one of the most common reasons a furnace goes cold, and it is also one of the most fixable. Most of the calls we get about it come down to the same worry: will this be a small repair or the start of a big bill?
Our answer is to find out before anything is replaced. A NATE-certified technician confirms the ignitor is the actual fault, checks the parts around it, and explains the price before work begins. We use flat-rate pricing so you know the number up front, and our work carries a workmanship guarantee.
Colorado Springs sits at high altitude, and that affects how gas furnaces burn and how they should be set up. A technician who works in this climate every day knows what to look for when a furnace is struggling to light, which is part of why we think a local, experienced crew is the better choice than a part from a box and a video.
We also tell homeowners honestly when a repair stops making sense. If your furnace is old, the repairs are stacking up and a new unit would serve your family better, we will show you the numbers on both and let you decide.
Owner
When an ignitor repair is not the whole story
An ignitor repair is cheap relative to a furnace. That makes it an easy yes on a newer, well-maintained system. The harder question comes with older equipment.
Carrier’s furnace repair guidance says that if a furnace is over 15 years old and the repair estimate approaches 50% of a new furnace’s cost, replacement may be worth considering. An ignitor job almost never approaches that line by itself. The concern is the pattern. If this is the second or third repair in a season, or the ignitor is one of several aging parts, you may be paying to keep a system alive that is close to the end.
We cover this decision in detail in our posts on furnace repair versus replacement and furnace lifespan and repeat repairs, and in our Colorado Springs repair or replace guide.
For budgeting, here is what a replacement looks like at our shop. These are published starting prices for equipment and installation, and your final quote depends on your home.
| Furnace | Starting price |
|---|---|
| 80% AFUE Two-Stage Variable Speed Furnace | from $4,500 |
| 96% AFUE Variable Speed Condensing Gas Furnace | from $6,500 |
| 98% AFUE Modulating Gas Furnace | from $8,250 |
The comparison is not meant to scare anyone. A $200 to $400 ignitor repair on a furnace that is otherwise healthy is a sound decision. A repeat repair on a furnace past 15 years is the moment to put a replacement quote beside it and compare.
Other home repair costs worth budgeting
A furnace rarely fails in isolation. If you are building a repair budget for the winter, it helps to know what neighboring systems cost too. A breakdown of water heater repair costs gives a sense of typical ranges for that appliance, which often sits in the same utility closet as the furnace.
How to get an honest ignitor quote
Whether you call us or anyone else, the same habits protect your wallet.
Ask what the diagnostic or service fee is and whether it is credited toward the repair. Ask whether the quote includes the part, labor and a post-repair ignition test. Ask if the part is OEM or universal. Ask whether the repair is covered by any workmanship guarantee and for how long. And ask for the total in writing before work starts.
A good contractor will answer each of those without hesitation. If a quote is vague, or the number changes after the technician arrives without a clear reason such as a damaged bracket or a second failed part, that is a signal to slow down.
If your furnace is under a manufacturer warranty, check it first. Carrier says manufacturer warranties on functional parts such as the ignitor typically cover the part for a set period but generally not the labor, so you may still owe the service charge even when the part itself is free. Confirm that with the manufacturer or your installer before you assume the whole job is covered.
For Colorado Springs homeowners who want a cost check on heating repairs in general, our post on affordable furnace repair in Colorado Springs explains how we keep repair costs reasonable without cutting corners.
Get your furnace lit and know the price first
If your furnace is not lighting, we can diagnose the cause, tell you the price before we start and get the heat back on. We serve Colorado Springs and nearby communities including Monument, Fountain, Divide, Ellicott and Black Forest, and our technicians are NATE-certified.
See our furnace repair and tune-up services or, if you are weighing a new system, our furnace pricing page. A yearly tune-up is also one of the best ways to catch a weak ignitor before it leaves you without heat in the middle of a cold snap.
FAQ
How much does it cost to replace a hot surface ignitor?
The part alone is typically $15 to $100, depending on whether it is a universal or OEM part. With professional installation, published guides put the total between about $100 and $425. HomeGuide’s average is $175, and Today’s Homeowner reports $300 to $425. Urgent or after-hours calls can cost more.
Can I replace a furnace ignitor myself?
We recommend against it. Carrier says ignitors are delicate and high-voltage, and that improper installation by non-professionals can lead to gas leaks, electrical hazards and carbon monoxide exposure. A non-authorized part can also void your manufacturer’s warranty. A licensed technician also confirms the ignitor is truly the problem.
How do I know if my furnace ignitor is bad?
Common signs are no heat, a furnace that cycles on and off, no orange glow from a hot surface ignitor, or repeated clicking on a spark-ignition system. Check your filter, thermostat and furnace switch first, since they can cause similar symptoms. If the basics are fine, schedule a diagnosis.
How long does a furnace ignitor last?
There is no single answer. Carrier gives no universal replacement interval, and life span depends on how often the furnace runs, the quality of the part and how it was installed. Regular maintenance helps a technician spot a weakening ignitor before it fails.
Is it worth replacing the furnace instead of the ignitor?
Usually not for an ignitor alone. Carrier suggests considering replacement when a furnace is over 15 years old and a repair estimate approaches half the cost of a new furnace. If you are facing repeated repairs on an older system, get a replacement quote to compare.
