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
Northeast and mountain states. Heat pump runs cheaper annually.
Cooling efficiency drives summer savings. Heating savings vary with gas price.
The comfort, longevity, and CO₂ benefits may still justify the switch.
HSPF2 ≥ 9 models maintain efficiency at -13°F. NEEP-listed products required for 25C.
