Heat pump cost in Connecticut

A furnace plus AC is roughly $1,850 a year cheaper to run in Connecticut: $3,643 (heat pump) against $1,792 (furnace + AC) per year for a 2,000 sq ft house, using 27.97¢/kWh power and $1.63/therm gas.

Energy bills compared

Heat pump heat, 7.5 / 9.5 HSPF2$3,455 / $2,728
Heat pump cooling, 14.3 SEER2$188
Furnace, 95% / 80% AFUE$1,592 / $1,890
AC at 13.4 SEER2 (North min)$201
Heat pump vs furnace + AC$3,643 vs $1,792

Expect to pay roughly $1,850 a year more with the heat pump; it makes most sense if your AC needs replacing too.

27.97¢/kWh (EIA, July 2026 YTD); gas $1.63/therm (EIA 2025, $16.83/Mcf at 1,031 Btu/ft³). Energy only; estimates.

Winter performance

Here heating dominates, so winter efficiency decides the outcome. Jan's degree days imply a monthly mean near 28°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. The numbers behind that: 5,849 heating and 607 cooling degree days a year (NOAA nClimDiv).

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

Upfront price

Tier to price first in Connecticut: 18–19 SEER2 / 9–10 HSPF2, roughly $11,000–$18,000+ installed (national estimate). Across all efficiency levels, a 2,000 sq ft home typically runs $10,000–$20,000+. No state-specific price data exists in our sources.

Connecticut heat pump FAQ

Heat pump price in Connecticut?

$10,000–$20,000+ installed for a 2,000 sq ft home, per HomeGuide's national figures.

When does a heat pump win in Connecticut?

About 12.9¢/kWh for a 7.5 HSPF2 heat pump against a 95% furnace at $1.63/therm; prices would need to fall about 15.1¢ from Connecticut's 27.97¢ average. A 9.5 HSPF2 unit would heat for $2,728 a year.

Does the 25C credit still apply?

No. Per the IRS, the Energy Efficient Home Improvement Credit (25C) covered improvements made through December 31, 2025, at 30% up to $2,000 a year for heat pumps, with a QMID requirement for 2025 property. IRS: Energy Efficient Home Improvement Credit.

Will a heat pump keep up in a Connecticut winter?

Standard units lose capacity in deep cold; with 5,849 heating degree days, choose a cold-climate model or keep gas backup.
