Frequently Asked Questions
How much does a furnace repair cost on average?
Most furnace repairs cost between $150 and $600, including the diagnostic fee. Simple fixes like replacing a flame sensor or capacitor are on the lower end ($75–$250), while major repairs like a heat exchanger can run $500–$1,500.
What is a furnace diagnostic fee?
A diagnostic fee (also called a service call fee) is what the technician charges to come to your home and identify the problem. This typically ranges from $75 to $150 and is usually credited toward the repair if you hire them.
Does emergency furnace repair cost more?
Yes. Emergency and same-day furnace repairs typically cost 50% more than standard service. After-hours service (evenings, weekends, holidays) adds about 25% more. If it's not an emergency, scheduling a regular appointment can save you hundreds.
Why does location affect furnace repair cost?
Labor rates and cost of living vary significantly by state. For example, furnace repairs in California or Hawaii cost 30–40% more than in Mississippi or West Virginia. Our calculator adjusts for these regional differences.
What is the most expensive furnace repair?
A cracked heat exchanger is the most expensive furnace repair, typically costing $500–$1,500 for parts and labor. Because of the high cost, a heat exchanger replacement on an older furnace often makes replacement the better financial choice.
