How much is the Mass Save heat pump rebate in 2026?

For air-source heat pumps installed January 1 – December 31, 2026: whole-home installations earn $2,650 per ton up to $8,500; partial-home installations earn $1,125 per ton up to $8,500 (integrated control required when fossil heat remains); basic installations earn $250 per ton up to $2,500. Income-eligible households can qualify for up to $16,000, or no-cost installation through Turnkey Services. A $500 weatherization bonus and $500 sizing bonus are also available.

Did the Mass Save whole-home rebate go down in 2026?

Yes. The whole-home air-source heat pump rebate changed from $3,000 per ton capped at $10,000 to $2,650 per ton capped at $8,500 effective January 1, 2026.

Are R-410A heat pumps still eligible for Mass Save rebates?

R-410A systems are being phased off the Mass Save Qualified Product List in 2026 as the industry transitions to next-generation refrigerants such as R-32 and R-454B. Contractors should verify a specific model is on the current QPL before quoting a rebate.

Who can perform a Mass Save heat pump installation?

To qualify for whole-home and partial-home rebates, the system must be installed by a contractor participating in the Mass Save Heat Pump Installer Network (HPIN). Equipment must meet ENERGY STAR Cold Climate standards per the Mass Save Qualified Products List.

Can Mass Save rebates be combined with NEHPA?

They operate at different layers: NEHPA is a wholesale discount paid through distributors to contractors at the point of equipment purchase, while Mass Save rebates are consumer incentives paid on the installed project. In general a contractor can buy equipment with the NEHPA discount and the homeowner can still pursue Mass Save rebates on the qualifying installation — verify current program rules before committing numbers in a quote.

What is the Mass Save HEAT Loan?

The HEAT Loan offers 0% financing up to $25,000 toward qualified energy-efficiency home improvements, including heat pump installations, through participating lenders.

Mass Save Heat Pump Rebates 2026: Contractor Guide

The 2026 rebate structure at a glance

Tier	Amount	Cap	Key condition
Whole-home	$2,650 / ton	$8,500	Heat pump is the sole heating & cooling source
Partial-home	$1,125 / ton	$8,500	Integrated control (from the qualified list) required where fossil heat remains
Basic	$250 / ton	$2,500	Installations not meeting whole/partial criteria
Income-eligible	Up to $16,000		Or no-cost install via Turnkey Services

Tonnage is calculated as AHRI cooling capacity divided by 12,000 BTU. Two stackable bonuses: a $500 weatherization bonus (home energy assessment + recommended work completed) and a $500 sizing bonus (system sized to 90–120% of the home's total heating load). Installations must land between January 1 and December 31, 2026.

The change that matters for quotes: 2025's structure was $3,000/ton with a $10,000 cap. A 4-ton whole-home job that earned $10,000 last year earns $8,500 now. If a homeowner is comparing your quote against a neighbor's from last fall, that $1,500 gap is the program, not you — say so explicitly in the quote conversation.

The R-410A phase-out is the quiet deadline

As the industry transitions to next-generation refrigerants, R-410A systems are being phased off the Mass Save Qualified Product List in 2026. Practically, that means equipment choice is now a rebate-eligibility decision:

Quoting a rebate job? Verify the specific model is on the current QPL before you commit numbers — not the model family, the specific AHRI match.
Sitting on R-410A inventory? Those units still work and still sell — but plan them into non-rebate applications rather than Mass Save jobs.
Stocking for 2026-27: prioritize R-32 / R-454B cold-climate models. That's where every program dollar is pointed.

Requirements checklist (whole-home / partial-home)

Installer: must be in the Mass Save Heat Pump Installer Network (HPIN) — if you're not enrolled, that's the gate to the two big tiers.
Equipment: ENERGY STAR Cold Climate, on the Mass Save Qualified Products List.
Partial-home: integrated control from the qualified control list wherever fossil heating stays.
Bonuses: document the load calculation for the sizing bonus (90–120% of heating load) — it's $500 for paperwork you should be doing anyway.

How NEHPA stacks underneath Mass Save

These two programs live at different layers of the transaction, which is exactly why they combine well:

	NEHPA	Mass Save
Who gets paid	You (the contractor), as an instant wholesale discount	Your customer (the homeowner), after installation
Where it happens	On the distributor invoice — at Ventrix, up to $650 per qualifying condenser	On the project rebate application
Paperwork	None for you — we handle VEIC reporting	Standard Mass Save rebate process

In general, buying your equipment with the NEHPA discount doesn't consume the homeowner's Mass Save eligibility — one is a wholesale-channel incentive, the other a consumer incentive. It means your quote can carry both a lower equipment cost and the full consumer rebate story. Program rules evolve, so confirm current stacking terms before locking numbers into a signed quote. Full program mechanics in our NEHPA contractor guide.

Financing: the HEAT Loan still closes deals

The 0% HEAT Loan up to $25,000 remains the strongest financing instrument in the state for this work. For a homeowner staring at a five-figure installed price, "zero percent, seven years, through your own bank" changes the conversation — pair it with the rebate table above and the out-of-pocket story gets dramatically easier to tell.

Frequently asked questions

Did the whole-home rebate really go down in 2026?

Yes — from $3,000/ton capped at $10,000 to $2,650/ton capped at $8,500, effective January 1, 2026. The income-eligible enhanced path (up to $16,000 / Turnkey) is unchanged in ceiling.

Can homeowners still get anything on a partial (single-zone) install?

Yes: $1,125/ton up to $8,500 for partial-home installations with a qualifying integrated control where fossil heat remains, or the basic $250/ton (max $2,500) tier otherwise.

Is TCL equipment eligible for Mass Save?

Eligibility is model-by-model: the unit must be on the current Mass Save Qualified Products List (ENERGY STAR Cold Climate, next-gen refrigerant). Ask our counter team to confirm the specific AHRI match you're quoting — and note qualifying TCL cold-climate models also carry the NEHPA wholesale discount.

What about the federal 25C tax credit?

The federal energy-efficiency tax credit landscape has shifted repeatedly — verify current 25C status with a tax professional before including it in a customer quote. We deliberately keep this guide to the state programs we can verify.
