Mass Save rebates & the 0% HEAT Loan.
In 2026, Massachusetts homeowners can get up to $8,500 in Mass Save rebates on a whole-home heat pump — up to $16,000 if income-eligible — plus 0% financing up to $25,000 through the HEAT Loan. The catch: the system must be properly sized, use 2026-compliant refrigerant, and be installed by an HPIN contractor. Nexis is HPIN and files it all for you.
How the money works
Up to $8,500 back, 0% to finance the rest
Mass Save is the primary heat pump incentive in Massachusetts, and it's substantial. The rebate tier depends on how much of your home the heat pump heats, how it's sized, and whether you weatherize.
Nexis is a Mass Save Heat Pump Installer Network (HPIN) contractor, which the top rebate tier requires. We size your system with Manual J, install qualifying cold-climate equipment, and file every rebate and HEAT Loan form — so you actually receive the incentive instead of leaving it on the table.
The 2026 Mass Save heat pump incentives
- Whole-home rebate: up to $8,500 — $2,650 per ton, capped at $8,500, when the heat pump is your whole-home heating source.
- Manual J right-sizing — sizing at 90–120% of design load, required to qualify for the full whole-home rebate.
- Separate weatherization incentives — Mass Save insulation/air-sealing incentives may apply on top of the heat pump rebate.
- Income-eligible: up to $16,000 — enhanced rebates, with a no-cost "Turnkey" path for qualifying households.
- 0% HEAT Loan up to $25,000 — 0% interest, terms up to 7 years (84 months).
- HPIN + compliant refrigerant — required for the top tier; we install R-454B/R-32 equipment on the qualified list.

Authorized on the network
A Mass Save Heat Pump Installer
Nexis is an authorized installer in the Mass Save Heat Pump Installer Network (HPIN) — the exact credential that unlocks the top-tier whole-home rebate of up to $8,500 (up to $16,000 if income-eligible). Many contractors aren't enrolled, so their customers simply can't claim it. We're on the network, and we file the paperwork for you.

Driving electric?
EV charger rebates in Massachusetts
Installing a Level 2 home charger? Your utility helps pay for the electrical work. Eversource rebates up to $1,400 and National Grid up to $700 toward the wiring or panel upgrade a 240-volt charger needs — and Nexis, as licensed electricians, does that work and folds the rebate into your project.
For details, visit the official Mass Save EV charging website.
The refrigerant rule matters in 2026
As of 2026, R-410A systems no longer qualify — equipment must use R-454B or R-32, be on the Mass Save Qualified Product List, and be ENERGY STAR cold-climate rated. Nexis only installs qualifying equipment, so your rebate isn't at risk. (All figures as of 2026, verified at your assessment.)

Mass Save FAQ
Answers, straight up
For a whole-home system the rebate is about $2,650 per ton, capped at $8,500. Income-eligible households can qualify for up to $16,000, including a no-cost Turnkey path, and separate Mass Save weatherization incentives may apply. Partial-home and basic tiers are lower. Figures are verified at your assessment.
The Mass Save HEAT Loan offers 0% interest financing up to $25,000, with terms up to 7 years (84 months), for qualifying heat pump and weatherization work. We handle the application as part of your project.
The top Mass Save rebate tier requires installation by a contractor in the Heat Pump Installer Network (HPIN). Nexis is an HPIN installer, so your project is eligible for the highest incentive.
R-410A systems no longer qualify for the top rebates. Qualifying equipment uses R-454B or R-32, must be on the Mass Save Qualified Product List, and be ENERGY STAR cold-climate rated. We install only qualifying equipment.
Because Mass Save is the primary heat pump incentive in Massachusetts — the difference between the top tier and a partial one is thousands of dollars, and it hinges on HPIN installation, Manual J sizing, and 2026-compliant equipment. We handle all of it.
