Furnace repair cost by part.
Typical Keene repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in Keene, New Hampshire, typically costs between $70 and $3,000+, depending on the component. With a median home built in 1958, many Keene homes have older furnaces that may need more frequent repairs. Local labor rates and the need for a mechanical permit (required by New Hampshire state code) add to the baseline cost. Given the cold climate, proper sizing and cold-climate heat pump considerations (for dual-fuel setups) are important for reliable heating.

Recommended unit for Keene
Given New Hampshire’s cold climate and mixed heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most Keene homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.

What Keene code requires
Installing or replacing an HVAC system in Keene follows New Hampshire rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-climate sizing matters: NHSaves rebates require cold-climate heat pumps rated for low ambient (NEEP-listed) performance, and equipment must use R-32/R-454B (R-410A no longer allowed).

What Affects Furnace Repair Costs in Keene
Repair costs in Keene vary by the part replaced: flame sensor ($70–$200), igniter ($125–$375), blower motor ($350–$1,250), control board ($250–$700), or heat exchanger ($1,250–$3,000+). A diagnostic fee of $65–$175 is typical. Older homes (median built 1958) may have harder-to-access systems, increasing labor time. New Hampshire requires a mechanical permit for repairs, which adds a fee. Choosing a dual-fuel system with a cold-climate heat pump (NEEP-listed) can affect long-term costs but may qualify for federal 25C tax credits.
Common Furnace Repairs in Keene
Flame Sensor Failure
A dirty or faulty flame sensor is a frequent issue in older Keene furnaces, causing the burner to shut off after ignition. Cleaning or replacement costs $70–$200.
Igniter Problems
A worn igniter can prevent the furnace from starting, common in systems over 10 years old. Replacement runs $125–$375.
Blower Motor Malfunction
