Heat pump replacements qualify for some of the most generous incentive stacks in residential home improvement — but the programs vary significantly by state and many have annual or quarterly caps. Late summer is often when state programs start running short of budget for the year, so understanding the stack and timing matters. Here's the current landscape.
Federal 25C tax credit — the foundation
The federal Residential Clean Energy Property Credit (25C) returns 30% of the total installed cost of qualifying heat pumps, capped at $2,000 per year. The credit is non-refundable but applies dollar-for-dollar against federal income tax liability. Through 2032 at the full $2,000 cap. Critical: only qualifying heat pumps (CEE Tier 1 or Tier 2 efficiency ratings, ENERGY STAR Most Efficient designation) qualify — not all heat pumps on the market. Confirm with the AHRI certificate before signing.
California — TECH Clean California + utility rebates
TECH Clean California offers heat pump rebates ranging from $1,000-$4,500 depending on equipment tier and income qualification. Stack with PG&E, SCE, SDG&E utility-specific rebates ($500-$1,500). LADWP customers see different programs. Self-Generation Incentive Program (SGIP) covers battery storage. Total stack with federal credit can exceed $7,000-$10,000 on a premium variable-speed install.
New York — Clean Heat program
NY Clean Heat (administered by ConEd, National Grid, NYSEG, RG&E) offers tiered rebates: $1,000-$3,000 for whole-home heat pump installs, $500-$2,000 for partial. NYSERDA offers 0% loans up to $25,000 for qualifying heat pump projects. Stack with federal credit can reach $5,000-$8,000 in total benefit.
New Jersey — Whole House Energy Solutions
NJ Clean Energy Program offers $300-$1,500 heat pump rebate; Whole House Energy Solutions adds $2,000-$4,000 when bundled with insulation and air-sealing work. Total stack with federal credit reaches $4,000-$7,500 for whole-house electrification projects.
Massachusetts — Mass Save (the most generous in the country)
Mass Save offers heat pump rebates up to $10,000 plus 0% HEAT Loans up to $25,000 (7-year term). For income-qualified households, 100% rebates may apply on whole-home heat pump conversions. Stack with federal credit makes Massachusetts heat pump installs frequently net out near $0 for cash purchasers.
Connecticut — Eversource and UI rebates
Eversource and United Illuminating offer $500-$1,500 instant rebates at point of sale (no paperwork to file). Connecticut Green Bank offers favorable financing. Stack with federal credit reaches $2,500-$4,500.
Florida and Texas — federal credit primary
Florida has no state heat pump rebate, but federal credit still applies. Some utilities (FPL, Duke Energy FL) offer modest equipment rebates. Texas: CenterPoint, Oncor, AEP offer utility-specific rebates ranging $200-$1,000. Federal credit is the primary incentive in both states.
Timing — why late summer matters
Many state rebate programs operate on annual or quarterly budget caps. By August, popular programs in CA, MA, and NY are sometimes already depleted for the year. Programs reset January 1 (calendar year basis) for most. If you're planning a heat pump install for this year, get quotes now and verify rebate availability with the installer before equipment selection.

How much can I save with heat pump incentives in 2026?
Federal credit returns up to $2,000 (30% of qualified installation cost). State stacks add $500-$10,000 depending on state and program. Most homeowners see total incentive value of $2,500-$8,000 on a typical residential heat pump install. Mass Save in MA can push incentives to nearly the full install cost for income-qualified households.
Are all heat pumps eligible for the federal tax credit?
No — only heat pumps meeting CEE Tier 1 or Tier 2 efficiency ratings or ENERGY STAR Most Efficient designation. Standard builder-grade heat pumps often don't qualify. Verify with the AHRI certificate number before signing any contract.
Do heat pump rebates stack with the federal tax credit?
Yes in nearly all cases. State and utility rebates reduce your out-of-pocket cost up front; the federal credit applies separately at tax time on the remaining installed cost. The combined effect can reduce net heat pump cost by 40-60%.
Can I still claim the federal heat pump credit if I lease the equipment?
No — leases and PPAs transfer the tax credit to the financing company. The 25C credit only applies to owned equipment (cash purchase or financed via a regular loan that you repay). If the credit matters to your math, structure the deal as ownership, not lease.
