Furnace repair cost by part.
Typical Farmington repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Farmington homeowners rely on gas furnaces to get through Minnesota's cold winters. With a median home built in 1997—about 29 years old—many systems are due for repairs. Typical furnace repair costs in Farmington range from $75–$225 for a flame sensor to $1,400–$3,300+ for a heat exchanger, plus a $70–$175 diagnostic fee. Minnesota requires a mechanical permit for furnace work, and any gas-line work must be done by a licensed plumber or gas fitter. For homes with moderate cooling demand, a dual-fuel heat pump system can qualify for the federal 25C tax credit (30%, up to $2,000). Proper cold-climate sizing is critical to avoid short cycling or inadequate heat.

- SEER2 minimum13.4 SEER2 (North)

- Load calculationRecommended

- Good to know—
Cold-climate sizing matters; gas-line work on a furnace must be done by a licensed plumber/gas fitter even if a homeowner pulls the mechanical permit.
