The cost to fix furnace ignitor typically ranges from $150 to $425 for professional replacement, including both parts and labor. Here's what you can expect to pay:
Quick Cost Breakdown:
- Ignitor part only: $20-$100
- Labor costs: $75-$200
- Total professional repair: $150-$425
- DIY part replacement: $20-$80
When your furnace won't heat your home, a faulty ignitor is often the culprit. This small but critical component reaches temperatures of 1,200 degrees Fahrenheit to ignite your furnace's gas burners. Without a working ignitor, your heating system simply can't produce heat.
The good news? Ignitor replacement is one of the more affordable furnace repairs you'll encounter. Unlike major components like heat exchangers or blower motors that can cost over $1,000 to replace, ignitors are relatively inexpensive parts with straightforward replacement procedures.
Several factors influence your final repair bill, including the type of ignitor your furnace uses, whether you need emergency service, and your location. Hot surface ignitors are most common in modern furnaces and typically last 3-7 years before needing replacement.
I'm Bill Scott, and over my 15 years in the HVAC industry, I've helped thousands of Pittsburgh-area homeowners understand the true cost to fix furnace ignitor issues and get their heating systems running efficiently again. My experience shows that informed homeowners make better decisions and avoid costly surprises when dealing with furnace repairs.
Cost to fix furnace ignitor terms to remember:
Is Your Furnace Ignitor Failing? Signs, Causes, and Lifespan
Your furnace ignitor might be small, but it's the hardest working component in your entire heating system. When this little powerhouse starts to fail, your home will feel the effects immediately - and so will your comfort level.
The most obvious sign something's wrong is when your furnace simply won't heat your home. You might notice cold air blowing from your vents, or worse yet, no air moving at all. This happens because your ignitor isn't doing its job of lighting the gas burners, leaving you with a furnace that's all dressed up with nowhere to go.
Listen carefully to your furnace, and you might hear persistent clicking sounds coming from inside the unit. Think of it like a lighter that keeps sparking but won't catch - that's your ignitor trying unsuccessfully to light the gas. It's frustrating for both you and your furnace.
Another telltale sign is short cycling, where your furnace starts up with good intentions, runs briefly, then shuts down without properly heating your home. This stop-and-start behavior often means the ignitor is partially working but can't maintain consistent ignition, or your system's safety features are kicking in.
If you're comfortable taking a peek inside your furnace (always turn off the power and gas first!), you might spot visible cracks running along the ignitor's surface. These hairline fractures are like wrinkles - they show age and wear, and they mean it's time for a replacement.
Common Causes of Ignitor Failure
Here's the reality about ignitors: they live a tough life and don't last forever. Most ignitors have a lifespan of 3 to 7 years, making them one of the most frequently replaced components in your heating system. Understanding why they fail helps explain the cost to fix furnace ignitor issues.
Age and normal wear top the list of failure causes. Every single time your furnace kicks on, your ignitor rapidly heats up to a scorching 1,200 degrees Fahrenheit, then cools back down when the cycle ends. Imagine doing jumping jacks in extreme heat, then immediately jumping into a cold shower - that's the kind of thermal shock your ignitor experiences dozens of times each day during heating season.
Frequent cycling accelerates this wear pattern significantly. If your furnace turns on and off more often than it should - perhaps because it's oversized for your home - your ignitor experiences extra stress cycles that shorten its life considerably.
Clogged air filters create a domino effect that impacts your ignitor. When airflow is restricted, your furnace works harder and runs hotter, creating additional stress on all components, including the ignitor. It's like trying to breathe through a straw while running a marathon.
Power surges and electrical issues can damage the delicate heating elements inside your ignitor. Even small voltage fluctuations can weaken the component over time, while major electrical events can cause immediate failure.
Dirt and debris accumulation around the ignitor can interfere with proper operation and heat dissipation. Moisture damage, while less common, can corrode connections and compromise the ignitor's integrity.
The fragility of hot surface ignitors deserves special mention. These components are so delicate that even touching them with bare hands can transfer skin oils that create hot spots, leading to premature cracking and failure.
Regular maintenance through a professional furnace tune-up can catch many of these issues before they result in complete ignitor failure, potentially saving you from emergency repair costs.
Types of Furnace Ignitors
Understanding the different types of ignitors helps explain why replacement costs vary and what you're actually paying for when you need repairs.
Hot Surface Ignitors (HSI) dominate modern furnace designs, having largely replaced older pilot light systems. These workhorses glow bright orange or white-hot when energized, providing reliable ignition for gas burners.
Silicon carbide ignitors represent the earlier generation of HSI technology. While effective, these ignitors are notably brittle and prone to cracking if handled roughly or subjected to sudden temperature changes. They glow with a distinctive red-orange color when operating.
Silicon nitride ignitors are the newer, improved version of HSI technology. These ignitors offer better durability and longer lifespans compared to their silicon carbide predecessors, making them a popular choice for replacements and upgrades.
Direct Spark Ignitors (DSI) appear in some older furnace models, working similarly to the ignition system in your gas grill. Instead of glowing hot, they create an electric spark to directly ignite the gas burners.
When most homeowners today face ignitor problems, they're typically dealing with HSI replacement, which represents the majority of modern furnace ignitor repair situations.
Breaking Down the Cost to Fix Furnace Ignitor
When your furnace ignitor fails, the uncertainty about repair costs can feel almost as uncomfortable as the cold air blowing through your vents. Let me break down exactly what you can expect to pay, so there are no surprises when our technician hands you the invoice.
The cost to fix furnace ignitor typically ranges from $150 to $425, with most of our customers paying around $300 for a complete professional replacement. This total includes both the ignitor part and the labor to install it properly.
While the ignitor part itself is surprisingly affordable, the total cost reflects much more than just a quick swap. You're paying for our certified technician's expertise, specialized tools, vehicle costs, insurance coverage, and most importantly, the peace of mind that comes with professional installation and safety protocols.
Think of it this way: when we arrive at your home, we're bringing 20+ years of experience, proper diagnostic equipment, and the knowledge to spot potential issues before they become bigger problems. That's worth far more than the few dollars you might save attempting a DIY repair.
Average Furnace Ignitor Part Costs
The good news about ignitor failures? The part itself won't break the bank. Most ignitors cost between $20 and $100, depending on whether you need a universal part or an Original Equipment Manufacturer (OEM) component.
Universal ignitors are the budget-friendly option, typically costing between $15 and $35. These are designed to work with multiple furnace brands and models, making them widely available and affordable. However, "one size fits most" doesn't always mean "perfect fit for your specific furnace."
OEM parts, on the other hand, range from $20 to $100 and are manufactured specifically for your furnace's make and model. While they cost a bit more upfront, they're engineered to exact specifications, ensuring optimal performance and maintaining your furnace's warranty coverage.
| Ignitor Type | Average Cost (Part Only) | Pros | Cons |
|---|---|---|---|
| Universal | $15 - $35 | More affordable, widely available | May not fit perfectly, potential for premature failure, can void warranty |
| OEM | $20 - $100 | Perfect fit, optimal performance, maintains warranty | Higher cost, may need to be ordered, less widely available locally |
In my experience, OEM parts are almost always worth the extra investment. I've seen too many callbacks where a universal ignitor failed within months because it wasn't quite right for that specific furnace. When you're dealing with something as critical as your home's heating system, spending an extra $20-40 for the right part makes perfect sense.
Typical Labor and Service Charges
Labor costs make up the larger portion of your cost to fix furnace ignitor, and for good reason. Our technicians bring specialized training, proper tools, and safety expertise that you simply can't get from a YouTube video.
Standard service calls typically include a minimum fee ranging from $75 to $200, which covers our technician's travel time, diagnostic work, and the actual replacement. Since ignitor replacement usually takes 15 to 45 minutes, you'll generally pay this minimum rather than an hourly rate.
Emergency service is a different story entirely. When your furnace quits on a frigid Saturday night or during a holiday, you'll pay premium rates - typically $140 to $210 per hour. We understand that heating emergencies don't follow business hours, which is why we offer 24/7 support, but that convenience does come at a higher cost.
After-hours and holiday charges reflect the reality that our technicians are giving up their evenings, weekends, and family time to keep your home comfortable. It's not just about paying more for the same service - it's about having access to professional help when you need it most.
For our customers throughout Pittsburgh, the South Hills, Burgettstown, Washington, Steubenville, St. Clairsville, and Weirton, our rates are competitive and transparent. We believe in upfront pricing, so you'll know the cost before any work begins.

Key Factors That Influence Your Final Bill
Several variables beyond the ignitor itself can significantly impact your final cost to fix furnace ignitor. Understanding these factors helps you budget appropriately and avoid surprises when the technician provides your estimate.
Furnace age plays a bigger role than many homeowners realize. If your furnace is over 15 years old, finding the exact OEM ignitor might require special ordering, which can increase both part costs and wait times. Older furnaces also tend to have accessibility challenges, as they were often installed in tighter spaces before modern building codes required better access for maintenance.
The accessibility of your furnace directly affects labor time and difficulty. A furnace tucked away in a cramped basement corner or crawl space takes longer to service than one in a spacious utility room. Our technicians need adequate space to work safely and efficiently, especially when dealing with gas and electrical connections.
Geographic location creates notable price variations across different markets. Labor rates in urban areas typically run higher than rural locations due to higher operating costs and demand. For our service areas covering Pittsburgh PA, South Hills PA, Burgettstown PA, Washington PA, Steubenville OH, St. Clairsville OH, and Weirton WV, we maintain competitive pricing that reflects local market conditions while ensuring quality service.
Timing matters tremendously for your final bill. Emergency calls during evenings, weekends, or holidays command premium rates because they require technicians to be available outside normal business hours. While we offer 24/7 emergency support for those urgent situations, standard business hour appointments will always be more budget-friendly.
Warranty coverage can dramatically reduce your out-of-pocket expenses, though it's important to understand exactly what's covered before assuming you're protected.
How Warranties Impact the Cost to Fix Furnace Ignitor
Warranties can significantly reduce your cost to fix furnace ignitor, but the details matter more than most homeowners realize.
Manufacturer's warranty typically covers parts for up to 10 years on newer furnaces. This means the ignitor itself might cost you nothing if it fails within the warranty period. However, here's the catch - manufacturer warranties almost never cover labor costs. You'll still pay for our technician's time, which ranges from $200 to $350 for ignitor replacement.
There's another important warranty consideration: using non-OEM parts or attempting DIY repairs will void your manufacturer's warranty entirely. This could leave you unprotected for future repairs on much more expensive components.
Home warranty plans work differently than manufacturer warranties. These service contracts typically cost $350 to $700 annually and cover various home systems. However, they might not make financial sense for ignitor repairs. When you factor in the annual premium plus service fees (usually $75 to $125 per visit), you might spend more on the warranty than the actual repair would cost.
We often recommend saving your home warranty claims for major component failures where repair costs exceed $1,000. An ignitor replacement rarely justifies using your annual warranty benefits.
Repair the Ignitor or Replace the Furnace?
The question of repair versus replacement comes up frequently, but for ignitor issues, the answer is almost always repair. The cost to fix furnace ignitor represents a fraction of what you'd spend on a new furnace installation.
A complete furnace replacement typically costs $4,000 to $7,000, while ignitor replacement maxes out around $425. That's roughly 10% of a new furnace cost for what's essentially routine maintenance on an otherwise functional heating system.
However, certain situations might tip the scales toward replacement. Older furnace efficiency becomes a concern when your unit approaches 15-20 years of age. If your furnace efficiency has declined significantly and you're facing multiple repairs each season, the cumulative costs start adding up quickly.
Frequent repairs create a different calculation entirely. When you're calling for service multiple times per heating season, those $300-400 repair bills accumulate rapidly. At some point, continuing to repair an aging furnace becomes financially impractical compared to investing in a reliable new system.
The Department of Energy suggests that older furnaces with frequent component failures often benefit more from replacement than continued repairs. Department of Energy advice on furnace upgrades provides excellent guidance on making this decision.
We're always honest about whether repair or replacement makes the most sense for your specific situation. Our goal is your long-term comfort and budget, not just the immediate repair.

DIY vs. Professional Replacement
The internet is full of guides on how to replace a furnace ignitor yourself. While the part is inexpensive and the process might look straightforward in a YouTube video, I need to share some honest truths with you. This isn't just about saving a few dollars - it's about your family's safety and protecting your furnace investment.
Here's the reality: furnaces combine natural gas with high-voltage electricity to create controlled explosions that heat your home. When something goes wrong with a DIY repair, the consequences can be serious. I've seen gas leaks, electrical fires, and carbon monoxide issues that started with well-intentioned DIY attempts.
Hot surface ignitors are also incredibly fragile - think of them as being more delicate than a light bulb. The oils from your bare hands can create weak spots that cause premature failure. I can't count how many times homeowners have called us after accidentally cracking a brand-new ignitor during installation.
There's also the warranty issue to consider. Many furnace manufacturers clearly state that repairs performed by non-certified technicians can void your warranty coverage. That small savings on labor could cost you thousands if you need a major repair later.
DIY vs. Professional: Estimating Your Cost to Fix Furnace Ignitor
Let's talk numbers honestly. The DIY approach might seem appealing when you're looking at a $30 to $80 ignitor part versus a $300 to $425 professional repair. That's real money, and I understand the temptation.
But here's what those DIY cost calculators don't tell you: you're gambling with much higher stakes. If you make a mistake during installation, you could damage other furnace components, create safety hazards, or end up paying for multiple service calls to fix the original problem plus any new issues you've created.
Professional installation brings long-term reliability and peace of mind. When our certified technicians handle your ignitor replacement, you're not just paying for 15-45 minutes of work. You're investing in our 20 years of experience, proper diagnostic equipment, and the knowledge to spot other potential problems before they become expensive emergencies.
Our technicians follow a precise safety protocol that ensures your repair is done right the first time. We shut down the furnace completely at both the breaker and gas valve before starting any work. We access the ignitor carefully, removing panels and components without damage. During installation of the new ignitor, we handle it with proper tools and techniques to prevent cracking or contamination.
Most importantly, we test the entire system thoroughly after installation. We don't just check if the ignitor glows - we verify proper ignition timing, flame characteristics, and system cycling. We also look for diagnostic codes that might indicate other developing issues.
This comprehensive approach means you get a repair that lasts, plus the confidence that comes with professional workmanship. That's worth the difference in cost when you're talking about your family's comfort and safety.
Frequently Asked Questions about Furnace Ignitor Repair
Over my 15 years in the HVAC business, I've noticed that homeowners often have the same questions about furnace ignitors. Let me share the answers to the most common ones we hear at Smart Climate Solutions.
How long does it take to replace a furnace ignitor?
When you call us for ignitor replacement, you won't be waiting around all day. A professional technician can typically complete the job in 15 to 45 minutes, depending on your furnace's setup.
The timing really comes down to accessibility. If your furnace is tucked away in a cramped crawl space or has multiple access panels to remove, it might take closer to 45 minutes. On the other hand, a furnace in a spacious utility room with easy access can often be serviced in just 15 minutes.
Sometimes we encounter additional complications - maybe the mounting bracket needs adjustment or there's some corrosion on the wiring connections. These situations might add a few extra minutes, but we always work efficiently while prioritizing safety and quality.
Are all furnace ignitors universal?
This is probably the most common misconception we encounter. While you'll find plenty of "universal" ignitors at hardware stores, not all furnace ignitors are truly universal.
Universal ignitors are designed to fit a wide range of furnace makes and models, and they can work in many situations. However, some furnaces - especially newer or premium models - require specific OEM (Original Equipment Manufacturer) parts for proper fit and function.
Here's the thing: using the wrong ignitor isn't just about poor performance. It can actually be unsafe and might void your furnace warranty. We've seen universal parts fail prematurely because they weren't quite the right fit, leading to repeated service calls and frustrated homeowners.
That's why we always check your furnace model and recommend the correct part, whether that's a universal or OEM ignitor. It's better to get it right the first time than deal with problems down the road.
Should I replace the flame sensor at the same time as the ignitor?
For furnaces over 7 years old, replacing both the ignitor and flame sensor together is often a smart move that can save you money on the cost to fix furnace ignitor issues in the future.
Think of the ignitor and flame sensor as dance partners - they work closely together to keep your furnace running safely. The ignitor lights the gas, and the flame sensor confirms that a proper flame is present. If the sensor gets dirty or starts to fail, it can shut down your furnace even when the ignitor is working perfectly.
Since both components experience similar wear and tear over the years, it makes sense to address them together during a single service call. This preventative approach often costs less than paying for two separate visits, especially when you factor in service fees and labor charges.
We typically recommend this combo replacement for older furnaces because it gives you peace of mind and helps avoid those frustrating middle-of-winter breakdowns when one component fails shortly after the other.
Get a Reliable Fix for Your Furnace
