Heat pump cost in New Hampshire

Estimated yearly heating and cooling cost for a 2,000 sq ft New Hampshire home: $4,303 with a heat pump, $2,319 with gas heat and AC. 26.79¢ electricity makes the heat pump about $1,984 a year dearer to run in New Hampshire.

What it costs to install

National guides price a 2,000 sq ft air-source heat pump at $10,000–$20,000+ installed; we don't have New Hampshire-specific figures. The tier we'd quote first here (heating climate) is 18–19 SEER2 / 9–10 HSPF2, at $11,000–$18,000+.

Operating cost vs gas

Heat pump heat, 7.5 / 9.5 HSPF2$4,215 / $3,327
Heat pump cooling, 14.3 SEER2$89
Furnace, 95% / 80% AFUE$2,225 / $2,642
AC at 13.4 SEER2 (North min)$95
Heat pump vs furnace + AC$4,303 vs $2,319

Running cost penalty: $1,984 a year. The case for a heat pump here rests on replacing two systems with one.

26.79¢/kWh (EIA, July 2026 YTD); gas $1.79/therm (EIA 2025, $18.61/Mcf at 1,039 Btu/ft³). Energy only; estimates.

FAQ

What does a heat pump cost installed in New Hampshire?

National estimate: $10,000–$20,000+ for 2,000 sq ft. Local bids decide it.

What's the break-even power price in New Hampshire?

About 14.1¢/kWh for a 7.5 HSPF2 heat pump against a 95% furnace at $1.79/therm; prices would need to fall about 12.6¢ from New Hampshire's 26.79¢ average. A 9.5 HSPF2 unit would heat for $3,327 a year.

Can I still claim 25C for a heat pump?

The 25C credit ended with 2025: it applied to qualifying heat pumps placed in service through December 31, 2025 (30%, max $2,000 a year), and 2025 claims required a Qualified Manufacturer Identification Number. Nothing federal applies to a 2026 install. Source: IRS: Energy Efficient Home Improvement Credit.

Will a heat pump keep up in a New Hampshire winter?

Standard units lose capacity in deep cold; with 7,449 heating degree days, choose a cold-climate model or keep gas backup.

New Hampshire climate

NOAA's 1991–2020 record: 7,449 HDD and 299 CDD for New Hampshire. That means heating dominates, so winter efficiency decides the outcome. Jan's degree days imply a monthly mean near 21°F (rough approximation); standard heat pumps lose capacity in deep cold and lean on electric backup, so our HSPF2 figures are optimistic here and a cold-climate model is the safer pick.

Size for the winter load and confirm cooling isn't far oversized, or keep a furnace for the coldest days (dual fuel).
