Replacing a furnace ignitor is a common maintenance task for homeowners seeking reliable heating. The cost of a furnace ignitor varies based on type, brand, and installation factors, making it important to understand pricing details before making a purchase or scheduling repairs. This article outlines the typical price ranges, factors influencing costs, and tips on selecting quality ignitors for various furnace models.
| Type of Furnace Ignitor | Average Material Cost | Estimated Installation Cost | Typical Lifespan |
|---|---|---|---|
| Hot Surface Ignitor | $30 – $70 | $100 – $200 | 3 to 5 years |
| Standing Pilot Ignitor | $20 – $50 | $75 – $150 | 5 to 10 years |
| Pulse Ignitor | $50 – $100 | $125 – $250 | 4 to 7 years |
Types of Furnace Ignitors and Their Cost Differences
Furnace ignitors serve as a critical component in the heating system by igniting the fuel to produce heat. The most commonly used types in American homes include hot surface ignitors, standing pilot ignitors, and pulse ignitors. Understanding each type’s working principle and price range helps align your budget with your furnace’s requirements.
Hot Surface Ignitors
Hot surface ignitors are silicon carbide or silicon nitride elements that glow red-hot to ignite gas. They are popular in modern gas furnaces for their reliability and quieter operation. Material costs typically range from $30 to $70, depending on the brand and compatibility. Installation may cost between $100 and $200 when performed by a professional technician.
Standing Pilot Ignitors
Older furnace models often use standing pilot ignitors, which maintain a small flame that ignites the main burner. These ignitors are less expensive, with prices between $20 and $50. Installation expenses are usually lower, falling between $75 and $150. However, standing pilot systems are less energy-efficient and are gradually being replaced.
Pulse Ignitors
Pulse ignitors generate sparks to ignite the fuel and are found mainly in commercial or high-efficiency furnaces. Due to their technical complexity, the ignitor itself can cost $50 to $100, with installation running from $125 to $250.
Additional Factors Influencing Furnace Ignitor Costs
Several variables impact the final cost of replacing or installing a furnace ignitor beyond the ignitor type:
- Brand and Quality: Premium brands with better durability come at higher prices but offer longer lifespan and fewer replacements.
- Model Compatibility: High-end or less common furnace models may have more expensive or harder-to-find ignitors, increasing material costs.
- Labor and Location: Labor charges vary by region, technician availability, and whether additional repairs or diagnostics are needed.
- Emergency or Off-Hours Service: After-hours or emergency repairs can significantly boost installation fees.

- Repeated Furnace Ignition Failures: If the furnace struggles to ignite consistently, the ignitor may be faulty.
- Visible Cracks or Damage: Physical inspection revealing cracks on a hot surface ignitor indicates imminent failure.
- No Red Glow or Ignition Sound: For hot surface ignitors, absence of red glow during start-up suggests replacement.
- Burning Smell or Noise: Unusual smells or noises can signal ignitor issues affecting furnace function.
DIY Replacement vs. Professional Installation
While furnace ignitors are often replaceable by knowledgeable homeowners, professional installation is recommended for safety and optimal performance.
- Pros of DIY: Saves labor costs, quicker turnaround for minor repairs, learning opportunity.
- Cons of DIY: Risk of improper installation, electric shock hazard, voiding manufacturer warranty.
Professional contractors ensure correct part selection, proper setup, and diagnostic testing, providing peace of mind despite higher upfront costs.
How to Choose the Right Furnace Ignitor
Selecting the appropriate ignitor depends on matching furnace specifications and expected lifespan requirements.
- Consult Manufacturer’s Guidelines: Always refer to furnace manuals for compatible ignitor types and part numbers.
- Consider Replacement Frequency: If ignitors fail frequently, investing in higher-quality options may reduce long-term costs.
- Check Warranty and Return Policies: Purchasing from reputable suppliers with warranty coverage saves money if defects appear.
