Heat Pump vs Gas Furnace Calculator

Compare the 15-year total cost of a heat pump against a gas furnace + AC replacement. Section 25C is still active (up to $2,000). Enter your climate zone, home size, and real gas/electric rates to see where the break-even falls.

Active through December 31, 2032 for qualifying heat pumps

Estimates based on ACCA Manual J load calculations, NEEP ASHP specifications (2024), EIA energy rates, and AHRI efficiency data. Section 25C eligibility requires IRS Form 5695 — consult a tax professional. Get at least 3 installer quotes before making any financial decision.

Heat Pumps in 2026: Section 25D Is Gone, But Section 25C Lives On

The residential solar tax credit (Section 25D) expired December 31, 2025 — but the heat pump credit is different. Section 25C covers energy-efficient home improvements including heat pumps, and it remains active through 2032 at 30% of installed cost, up to $2,000 per year.

This means a $6,500 heat pump qualifies for a $1,950 federal tax credit. A $9,500 cold-climate model qualifies for the full $2,000. Combined with state rebates and the HEEHRA low-income program (up to $8,000), many homeowners can replace their gas furnace and air conditioner for under $2,000 net out-of-pocket.

When Heat Pumps Save Money — and When They Don't

High gas rates ($1.80+/therm) + moderate electricity (<$0.18/kWh)Strong savings

Northeast and mountain states. Heat pump runs cheaper annually.

Mixed climate (Atlanta, Dallas) with average ratesModerate savings

Cooling efficiency drives summer savings. Heating savings vary with gas price.

Cold climate with standard HP + cheap gas (<$1.20/therm)Energy costs similar or higher

The comfort, longevity, and CO₂ benefits may still justify the switch.

Very cold climate with cold-climate HP (Mitsubishi, Daikin, Bosch)Viable in most states

HSPF2 ≥ 9 models maintain efficiency at -13°F. NEEP-listed products required for 25C.
