Furnace Repair Cost in Minnesota: Common Repairs & Prices
Updated July 20266 min read
By the Eagan HVACs Editorial TeamA furnace that quits in a Minnesota winter feels like an emergency — and the price uncertainty makes it worse. The good news: many furnace repairs are inexpensive and same-day. Here's what common furnace repairs actually cost in the Twin Cities, so you can tell a fair price from a padded one, even at 10 PM in January.
If your furnace is getting on in years, check whether repair even makes sense with the repair-or-replace calculator before you commit.
Key takeaways
- Most furnace repairs run $150–$600; blower motors, control boards, and heat exchangers cost more.
- A dirty flame sensor or a failed ignitor — both cheap — cause a large share of no-heat calls.
- A cracked heat exchanger is a safety issue that usually means replacement, not repair.
- No-heat emergency visits on nights and weekends carry a premium — ask about it upfront.
Typical furnace repair costs in the Twin Cities
Parts and labor included. The diagnostic fee is usually quoted upfront and often credited toward the repair.
| Repair | Typical range |
|---|---|
| Flame sensor cleaning/replacement | $80 – $250 |
| Hot surface ignitor | $150 – $350 |
| Draft inducer motor | $300 – $900 |
| Control/circuit board | $400 – $1,200 |
| Blower motor | $400 – $1,500 |
| Heat exchanger (usually replace furnace) | $1,500+ |
What drives the price
- The failed part — a flame sensor is cheap; a blower motor or board is not
- No-heat emergency timing (nights, weekends, holidays)
- Your furnace's age and whether parts are still available
- High-efficiency (condensing) furnaces have more parts that can fail
A gas smell is not a repair — it's an emergency
If you smell gas near the furnace, leave the house, don't touch switches, and call your gas utility and 911 from outside first. Only address the furnace itself once you're safe.
Repair or replace?
A cracked heat exchanger is the clearest replacement trigger — it's a carbon-monoxide safety issue, and the part costs so much that a new furnace is usually the better spend. Beyond that, the rule of thumb holds: if the repair is more than about a third of a new furnace and yours is past 15 years, replace it. The furnace replacement cost guide shows what new systems run.
How to avoid overpaying
- Get the diagnosis and price in writing before work begins
- Ask what the emergency/after-hours premium is before booking, if it's not a true emergency
- For repairs over ~$800 on an older furnace, get the replacement number too
- Be wary of a heat-exchanger 'crack' diagnosis with no photo — ask to see it

FAQ
Related questions
How much does furnace repair cost in Minnesota?
Most furnace repairs run $150–$600 — a flame sensor or ignitor at the low end, a blower motor or control board higher. A cracked heat exchanger is the exception: it's a safety issue that usually means replacing the furnace rather than repairing it.
Why won't my furnace stay lit?
A furnace that lights then shuts off is often a dirty flame sensor — a cheap, common fix. It can also be a failing ignitor or a safety switch doing its job. A technician can pinpoint it quickly, and it's usually an inexpensive repair.
Is it worth repairing a 20-year-old furnace?
Often not, especially for a major part. Past 15–20 years, if the repair runs more than about a third of a new furnace, replacement usually makes more financial sense — and a new high-efficiency unit lowers your gas bill. Run the numbers with the repair-or-replace tool.
How fast can someone fix a no-heat furnace?
