Income-Qualified Heat Pump Installation in Massachusetts

Three income tracks, three funding pools

Income-qualified heat pump funding in Massachusetts in 2026 comes from three distinct sources that stack with each other:

• Mass Save Enhanced rebates — replace (don't stack with) the standard $8,500 cap with materially higher ceilings for households between approximately 60% and 135% SMI.
• Federal HEAR rebate — pays up to $8,000 toward the heat pump (and up to $4,000 toward an electrical panel upgrade) for households at or below 80% AMI.
• Mass Save Turnkey (no-cost) program — for households at or below 60% SMI, wraps the entire install — equipment, labor, permits, rebate filing — into a zero-out-of-pocket package.

Mass Save Enhanced rebates (60–135% SMI)

• Enhanced Air Source Heat Pump (Whole-Home): up to $16,000. Households between approximately 60% and 135% of State Median Income (SMI) on the moderate-income track. Replaces the standard $8,500 cap with up to $16,000 for whole-home air-source heat pump systems.
• Enhanced Ground Source (Geothermal) Heat Pump: up to $25,000. Households between approximately 60% and 135% of SMI on the moderate-income track. Customer account limit: maximum $25,000 across all enhanced incentive offerings. Replaces the standard heat pump rebate caps with up to $25,000 for ground-source (geothermal) systems.
• No-Cost Turnkey Heat Pump Program. Households at or below 60% of State Median Income. Eligible households can receive no-cost project management, contractor oversight, and equipment installation — Mass Save effectively covers the install end-to-end. Apply through the Income Eligible Programs portal.

For Massachusetts in 2026, 135% SMI for a four-person household is approximately $163,000. Anyone earning under that should ask the Mass Save auditor specifically about the Enhanced tier before defaulting to the standard $8,500 rebate. The Enhanced tier ceilings replace the standard caps; they do not stack on top of them.

Federal HEAR rebate (≤80% AMI)

• HEAR (Home Electrification & Appliance Rebates) — Heat Pump — up to $8,000 USD per household (federal program design; actual MA delivery routes through Mass Save income-eligible programs). Households at or below 80% of Area Median Income (AMI). Massachusetts has NOT launched HEAR as a standalone consumer rebate — Mass Save's own IRA page (verified 2026-05-27) confirms that DOER and the Mass Save sponsors are integrating HEAR funding into existing no-cost / enhanced income-eligible offerings rather than running it as a separately-claimable $8,000 rebate. Eligible households should apply through the Mass Save income-eligible pathway after completing a Home Energy Assessment.
• HOMES (Home Efficiency Rebates) — whole-home retrofit — up to $8,000 USD per household (varies by modeled energy savings and income tier). Open to all Massachusetts households; deeper rebates for those below 80% AMI. Delivered through the Mass Save Deep Energy Retrofit pathway. Requires modeled or measured energy-savings verification.

HEAR funding flows through MassCEC and the Mass Save Income-Eligible Programs pathway. Apply through a Mass Save Home Energy Assessment — the auditor will determine HEAR eligibility on-site. Read the dedicated HEAR program guide for full mechanics.

Mass Save Turnkey: the no-cost path

Households at or below 60% SMI typically route into the Mass Save Turnkey program. This is qualitatively different from the cash-rebate model: instead of buying equipment yourself and submitting a rebate, Mass Save's program administrators select an HPIN contractor on your behalf, manage the project end-to-end, and cover the full cost from the combined Enhanced + HEAR + HOMES funding pool. Out-of-pocket cost: $0 in most cases.

Turnkey is the most important program most Massachusetts homeowners have never heard of. If your household income is below 60% SMI (roughly $73,000 for a four-person household in 2026), this is what you should be asking about, not the standard rebate.

How to apply

1. Book a Mass Save Home Energy Assessment. Free, ~60–90 minutes on-site, typically 4–6 weeks out for scheduling. Mention "income-eligible" when you book so the auditor brings the right paperwork.
2. Bring income documentation. Most recent federal tax return, two months of paystubs for all working adults, or evidence of participation in another income-qualified program (SNAP, LIHEAP, MassHealth, etc.).
3. Auditor determines pathway. Standard, Enhanced, HEAR-stacked, or Turnkey — based on your household-income-to-SMI/AMI ratio and household size.
4. Equipment selected from the HPQPL. Cold-climate-certified, R-32 or R-454B refrigerant (post-2026 cutoff). For Turnkey participants the program administrator handles this.
5. Install and rebate filing. 1–2 weeks typical for ductless multi-zone in MA. Turnkey participants pay nothing out of pocket; Enhanced and HEAR-stacked participants pay the post-rebate balance, financeable via the HEAT Loan if needed.

What also stacks (and what doesn't)

• Stacks: Mass Save Enhanced + HEAR. HEAR + HOMES (different appropriations, different criteria). Heat pump rebate + heat pump water heater rebate (separate Mass Save line items).
• Does not stack: Standard $8,500 cap + Enhanced $16,000 cap (Enhanced replaces standard). Mass Save HEAT Loan + Turnkey (Turnkey eliminates the need to borrow).
• Expired and not coming back: Federal §25C tax credit ended December 31, 2025. Federal §25D geothermal credit ended the same day. Neither has been reinstated.
