How Much Does Furnace Repair Cost?

Most furnace repairs cost between $150 and $2,000, with the average homeowner paying $300-$500. The exact price depends on what's broken - a thermostat fix or clogged filter runs $150-$300, while a heat exchanger replacement can hit $2,000. Here's a full breakdown by repair type so you know exactly what's fair before you call anyone.

Most furnace repairs in 2026 fall between $150 and $2,000. The average homeowner pays around $300–$500. Here's a rough guide:

• Thermostat fix, clogged filter, tripped switch: $150–$300
• Ignitor, capacitor, draft motor: $300–$800
• Blower motor: $400–$1,200
• Heat exchanger: $500–$2,000

The final number depends on what's wrong, how old your system is, and whether parts need to be ordered. The U.S. Department of Energy notes that older furnaces often cost more to repair because parts are harder to find.

Here's what happens with a lot of HVAC companies: they quote you a low "diagnostic fee" to get in the door. Then once they've opened up your furnace, suddenly the price triples. Or they tell you the repair is $2,000 and you "might as well replace the whole thing" - even when a $400 fix would get you five more years. That pressure-sales approach works because you're cold, you're stressed, and you just want heat. They know that. And some of them use it against you.

Sometimes replacement really is the smarter move. If your furnace is over 15 years old and repair bills are piling up, the math may not work in your favor. A simple rule: if the repair costs more than half the price of a new furnace, replacement usually makes more sense. New high-efficiency furnaces cut heating costs by 20–30% compared to older models. But that should be your decision - not a sales pitch.
