How to Stack Heat Pump Rebates in 2026

How does rebate stacking actually work?

Rebate stacking combines federal tax credits, state HEEHRA rebates, state tax incentives, and utility programs into one payout on a single electrification project. After OBBBA repealed most federal credits, stackable savings now come mostly from state and utility programs. Smart stacking can offset fifty to ninety percent of heat pump installation cost.

Can I combine federal, state, and utility heat pump rebates?

Yes — stacking is allowed and encouraged. Federal tax credits (what remains after OBBBA), state HEEHRA rebates, state tax incentives, and utility rebates generally apply to different layers of the same install. Most homeowners can claim all that they qualify for in the same tax year on the same project.

What order should I apply rebates in?

Apply point-of-sale rebates first (HEEHRA, utility instant rebates) because they reduce the invoiced cost. Then apply mail-in or post-install utility rebates to the reduced invoice. Federal tax credits apply to your out-of-pocket cost after all rebates — you cannot claim a credit on money that was rebated.

Do rebates reduce each other?

Some do, some do not. HEEHRA and state tax credits typically stack independently. Utility rebates sometimes cap at a percentage of post-HEEHRA cost. Federal credits always apply to net out-of-pocket only. Read each program's stacking rules, or use the ElectrifyAtlas rebate finder to see the combined stack for your ZIP.
