Replacing a furnace ignitor is a critical maintenance task to ensure efficient heating during cold months. The cost of furnace ignitor replacement varies depending on the type, brand, labor, and geographic location. Understanding the factors affecting furnace ignitor replacement costs can help homeowners plan their budgets effectively and avoid unexpected expenses.
| Factor | Details | Cost Range |
|---|---|---|
| Ignitor Type | Hot surface vs. spark ignitor | $20 – $150 |
| Labor Charges | Service and installation fees | $75 – $250 |
| Furnace Brand | OEM parts vs. aftermarket | Variable |
| Location | Regional labor and parts price differences | Varies |
What Is a Furnace Ignitor and Why It Needs Replacement
A furnace ignitor is a vital component responsible for igniting the burners that heat air in a forced-air heating system. It typically functions either as a hot surface ignitor or a spark ignitor. Over time, repeated heating cycles cause the ignitor to degrade, which can lead to failure and heating issues. Replacing a faulty ignitor restores furnace operation and ensures safety and efficiency.
Types of Furnace Ignitors and Their Cost Differences
There are primarily two types of furnace ignitors:
- Hot Surface Ignitors: These are ceramic elements that heat up to ignite the gas. They are common in modern furnaces.
- Spark Ignitors: These generate an electric spark to ignite the gas burner and are found in older models.
Hot surface ignitors generally cost between $40 and $150, while spark ignitors are more affordable, typically $20 to $80. Replacement parts designed for specific furnace brands may increase the price accordingly.
Labor Costs and Installation Considerations
Labor costs for installing a new furnace ignitor depend on technician rates and the complexity of the job. Most homeowners can expect to pay between $75 and $250 for professional installation. Factors influencing labor charges include:
- Accessibility of the furnace unit
- Time required to diagnose the problem
- Additional repairs or calibrations needed
DIY replacement of furnace ignitors is possible for experienced homeowners but not recommended due to safety concerns and potential warranty voidance.
How Furnace Brand and Model Affect Replacement Costs
OEM (Original Equipment Manufacturer) ignitors tailored for specific furnace models can cost more than generic or aftermarket parts. Premium brands often carry higher replacement prices due to proprietary designs or enhanced durability features. For example:

| Furnace Brand | Approximate Ignitor Cost |
|---|---|
| Carrier | $90 – $140 |
| Trane | $80 – $130 |
| Lennox | $70 – $120 |
| Goodman | $40 – $90 |
Choosing genuine parts ensures compatibility but impacts overall cost.
Geographical Region Impact on Ignitor Replacement Pricing
Labor rates and parts availability vary significantly by region. Homeowners in large metropolitan areas or regions with higher living costs often pay more. In rural or less populated areas, pricing may be lower but part availability can be limited, possibly increasing wait times.
The average cost in the U.S. ranges from $150 to $400 for complete replacement, including labor.
Signs Your Furnace Ignitor Needs Replacement
Recognizing early symptoms of a failing ignitor helps prevent full furnace breakdowns. Common signs include:
- Furnace not heating despite blower running
- Intermittent heating or delayed burner ignition
- Visible cracks or discoloration on the ignitor
- Frequent furnace shutting off during operation
- Error codes related to ignition failure on digital thermostats
Timely replacement prevents energy waste and costly emergency repairs.
Comparison: Furnace Ignitor Replacement vs. Furnace Replacement Costs
| Service | Typical Cost Range | Notes |
|---|---|---|
| Furnace Ignitor Replacement | $150 – $400 | Quick fix, extends furnace life |
| Complete Furnace Replacement | $3,000 – $7,000+ | Major investment, necessary after system end-life |
Replacing the ignitor is a cost-effective maintenance option compared to full furnace replacement.
Tips for Reducing Furnace Ignitor Replacement Costs
- Schedule regular furnace maintenance to identify ignitor wear before failure.
- Shop around for competitive service quotes.
- Consider aftermarket parts cautiously, balancing warranty and price.
- Perform visual inspections periodically to catch damage early.
- Hire licensed and reputable technicians to ensure quality replacements.
