When your furnace stops working, the first thing on your mind is the price to fix it. Heating problems never come at a good time, and fast repairs matter when the temperature drops. The average cost of furnace repair in 2025 depends on the part that fails and how complex the repair is.
Some fixes are simple, but others can be costly. Below, we explain common repairs, what they cost, and when to call a pro.
Common Furnace Repairs and Costs
We work on many different furnace brands, and we’ve seen the same problems pop up over and over. Below are typical repairs and what they cost in 2025:
- Hot surface igniter: This is one of the most common repairs. If your furnace tries to run, but the burners don’t light, it’s likely the igniter. Estimated Cost: $300–$400
- Gas valve or circuit board: These are electrical parts that control your system. If they fail, your furnace won’t operate. Estimated Cost: Around $1,000
- Blower motor (especially variable-speed): These motors help move air through the system. Variable-speed models are efficient but expensive. Estimated Cost: $1,500 or more
- Heat exchanger (if out of warranty): This is the most expensive part to repair. If it cracks or fails, replacement might make more sense. Estimated Cost: $2,000–$3,000
Key Takeaway: The most common furnace repairs we see are for igniters and fan motors, especially during winter.
When Should You Call a Professional?
Furnaces have a set sequence of steps they follow before they blow hot air. If something interrupts that sequence, your system will shut down for safety. But why can’t homeowners fix furnace issues?
The truth is, modern furnaces are complex. They have pressure switches, control boards, and safety checks that require special tools and know-how. Unless you’ve worked on furnaces before, there’s not much you can do beyond:
- Replacing the air filter
- Checking the thermostat batteries
- Making sure the power switch is on
- If none of these simple checks work, it’s time to call a pro.

How a Furnace Works: The Sequence of Operation
Knowing how your system works can help you understand why a repair is needed. Here’s the basic order:
- Call for heat (your thermostat tells the furnace to start)
- Exhaust fan starts (also called the inducer)
- Pressure switch closes (shows air is flowing)
- Igniter lights
- Gas valve opens
- Burners fire
- Blower motor kicks on to push warm air through your home
Each part depends on the one before it. If one fails, the system won’t run.
Can You Troubleshoot Furnace Problems Yourself?
If you can use a voltmeter and know the furnace sequence, you can troubleshoot issues like:
- Fan running, but no heat
- Pressure switch not closing
- No power to igniter
But for most homeowners, it’s safer and faster to bring in a trained tech. Trying to guess could lead to more damage or no heat on the coldest night.
Pro Tip: If your furnace is 15+ years old and the repair is over $1,500, ask about replacement options. It might save money long-term.
In Summary
So, how much does a furnace repair cost in 2025? For small issues like igniters, expect $300–$400. Bigger repairs like blower motors and heat exchangers can run $1,500 to $3,000. The safest move is to call a trusted professional who can diagnose the issue and offer a repair plan that fits your budget.
