Massachusetts homeowners can cut thousands off a high-efficiency heat pump through Mass Save. Here’s how the rebates and 0% HEAT Loan work in 2026, and how CleanTap helps you use them.
Mass Save is a program run by Massachusetts’ utilities that offers rebates and 0% financing to help homeowners install high-efficiency equipment, especially heat pumps, which heat and cool your home and can replace older fossil-fuel systems. For many homes the incentives turn an efficient system from “someday” into an easy yes.
This page explains the current Mass Save heat-pump incentives in plain English and how CleanTap helps you choose qualifying equipment and take advantage of them. Rebate amounts and rules are set by Mass Save and change over time, treat the figures below as a 2026 snapshot and confirm current amounts before you commit.
As of 2026, Mass Save offers strong rebates for air-source heat pumps, scaled by system size (tons) and how the system is used:
About $2,650 per ton, up to $8,500 per home, when the heat pump is your sole heating and cooling source.
About $1,125 per ton (up to the same cap) when the heat pump works alongside an existing primary heating system.
A newer entry option around $250 per ton (up to $2,500) for heat-pump-to-heat-pump replacements or conditioning previously unconditioned space.
Additional bonuses may apply for right-sized equipment (Manual J) and for weatherization done with a home energy assessment.
Beyond rebates, the Mass Save HEAT Loan offers 0% APR financing up to $25,000 for qualifying energy-efficiency improvements, with repayment terms that vary by income. Combined with the rebate, this is what makes a heat-pump upgrade affordable for many households, you spread the net cost over time at no interest.
Because eligibility, amounts, and terms are set by the program and can change, we help you confirm what currently applies to your project before you decide.
CleanTap installs high-efficiency, Mass-Save-qualifying heat pumps and does the up-front work that maximizes your incentive, a proper load calculation (Manual J) to right-size the system, selecting cold-climate-rated equipment that performs through New England winters, and clean, permitted installation. We’ll walk you through which rebates and financing apply to your home and give you an upfront, fixed price.
The best first step is a free in-home assessment so we can size the system and estimate your net cost after incentives.
