Heat Pump Rebate Stacking Calculator 2026: IRA + State + Utility + HEEHRA + Manufacturer Matrix
Massachusetts max stack: $23,500 (HEEHRA $8K + Mass Save $10K + utility $4K + manufacturer $1.5K) — can result in NEGATIVE NET COST on a $14K cold-climate Mitsubishi install. Maine #2 at $17.5K. Texas, Florida laggers without HEEHRA yet. IRA Section 25C and HEEHRA are MUTUALLY EXCLUSIVE — middle/high income use IRA, below 150% AMI use HEEHRA. Here's the proprietary 2026 5-layer rebate matrix, 12-state stacking analysis, 8 CCHP-certified models, and HEEHRA income tier table.
Last updated April 2026. Data from IRA Section 25C + 50122, DOE HEEHRA implementation tracker, state energy office programs (Mass Save, NYS Clean Heat, Efficiency Maine, TECH CA), DSIRE, manufacturer rebate programs Q1 2026, HUD 2026 AMI tables.

Frequently Asked Questions
How much can I save on a heat pump in 2026?
Massachusetts max stack: IRA $2K + State $10K (Mass Save) + Utility $4K + Manufacturer $1.5K = $17,500. With HEEHRA (income-qualified): HEEHRA $8K + State $10K + Utility $4K + Manufacturer $1.5K = $23,500. On a $14K cold-climate Mitsubishi install in MA, this can mean NEGATIVE NET COST. Most states max stack: $5K-$15K.
Can I stack the IRA tax credit with HEEHRA rebate?
NO — must choose ONE. IRA Section 25C ($2K) is for households earning ABOVE 150% AMI. HEEHRA ($4K-$8K) is for BELOW 150% AMI. Mutually exclusive by design. Both can stack with state, utility, and manufacturer rebates. HEEHRA wins on dollar value if you qualify; IRA wins if you don't.
What is HEEHRA and which states offer it?
HEEHRA (Home Electrification and Appliance Rebate Act) is a $4.5B IRA Section 50122 program for low-to-moderate income households. Direct point-of-sale rebates of $4,000-$8,000 for heat pumps. April 2026 active states: CA, NY, MA, ME, VT, CO, IL (Q3), WA, OR. Pending DOE approval: NJ, TX, FL.
What income qualifies for the highest HEEHRA rebate?
Below 80% Area Median Income (AMI) = $8,000 max. National 2026 80% AMI: Single $71,450; Couple $81,600; Family of 4 $102,100; Family of 6 $118,450. 80-150% AMI tier ($102K-$191K family of 4) = $4,000 max. Above 150% AMI: not eligible for HEEHRA but qualifies for IRA $2K credit instead.
Which states have the best total heat pump rebates?
Massachusetts (#1) Mass Save delivers $10K+ before federal; potential $23K total stack. Maine (#2) Efficiency Maine $8K + cold-climate bonus. New York (#3) NYS Clean Heat $5K. Vermont (#4) $4.5K. California (#5) TECH $4K. Worst: Texas, Florida (no HEEHRA yet). Cold-climate states win because heat pumps are mandated as policy.
What models qualify for cold-climate heat pump rebates?
Cold-Climate Heat Pump (CCHP) certification required. Top 8 models 2026: Mitsubishi MSZ-FS Hyper-Heating (-13°F), Mitsubishi M-Series (-22°F), Carrier Greenspeed Infinity, Fujitsu Halcyon Hybrid Flex (-15°F), Bosch IDS Premium, Daikin Fit, LG Multi-Zone, Trane XV20i. All Energy Star + IRA Section 25C HSPF2 11.0+ minimum.
How do I claim the IRA $2,000 heat pump tax credit?
File IRS Form 5695 with federal return for year of installation. Requirements: HSPF2 11.0+ and SEER2 18+ Northern / 17.5+ Southern; primary residence; qualified contractor; keep manufacturer specs + receipt for 4-year audit. Annual cap $2,000 resets yearly — claim heat pump year 1, $1,200 insulation year 2, etc., until 2032 expiration.
Can I get a rebate on a ductless mini-split heat pump?
Yes — most programs cover ductless. IRA Section 25C explicitly includes ductless. Mass Save covers ductless at full $10K; NYS Clean Heat $5K; Maine $8K. Some utility rebates have lower caps for ductless vs central. Multi-zone systems (4+ heads) sometimes have higher rebate tiers.
