What's the most expensive furnace repair?

Heat exchanger replacement is typically the most expensive furnace repair — often $1,500–$3,500. At that cost, a new furnace is frequently the better investment, especially for systems over 12 years old.

Does a cracked heat exchanger need to be repaired right away?

Yes. A cracked heat exchanger can allow carbon monoxide to enter your living spaces — a serious health and safety risk. We recommend shutting the furnace off and getting the repair or replacement done promptly.

Is the diagnostic fee charged even if I don't proceed with the repair?

Yes, the diagnostic fee covers the technician's time to assess your system. If you authorize the repair, the diagnostic fee is applied toward the total cost.

When Furnace Repair Isn't Worth It

Heat exchanger replacement ($1,500–$3,500) on a furnace over 12 years old almost never makes financial sense — a new furnace is the better investment. For mid-range repairs ($300-$800) on newer furnaces, repair is usually the right call. If you're dealing with no heat or cold air from the vents, common repairs like ignitors and flame sensors are affordable and quick.
