Mass Save Energy Rebates in Massachusetts

Mass Save is a collaboration of MA's utility companies offering some of the strongest residential energy incentives in the country.

If you are renovating, you should know what is available.

Free Energy Assessment

Every Mass Save member home is eligible for a free no-cost home energy assessment. An auditor visits, runs a blower door test, evaluates insulation, checks HVAC, and identifies improvements.

You walk away with:

- Free LED bulbs

  • Free smart power strips
  • Free programmable thermostat (in many cases)
  • Free low-flow showerheads and aerators
  • A custom improvement plan
  • List of incentives available for your home

    Heat Pump Incentives

    If you are replacing fuel oil, propane, or electric resistance heating:

    - Significant rebates on whole-home heat pumps

  • Zero-percent HEAT Loan financing for substantial amounts
  • Additional incentives for income-qualified households

    We coordinate with HVAC contractors on whole-home or addition heat pump installations.

    Insulation Rebates

    For attic, wall, or basement insulation:

    - Up to 75% rebate on installed cost (residential)

  • 100% on attic insulation for income-qualified
  • Coverage for air sealing, including pre-existing leaks

    This pairs perfectly with a roofing or remodel project — if we are already in the attic or behind the walls, adding insulation is efficient.

    Windows and Doors

    Rebates available for Energy Star certified windows and doors, particularly when replacing single-pane or pre-2000 double-pane windows.

    How We Coordinate with Mass Save

    When we do a renovation:

    ✅ We check whether the project qualifies for Mass Save incentives ✅ We provide documentation Mass Save needs for rebate processing ✅ We can stage work to take advantage of incentive timing ✅ For heat pump or insulation work, we coordinate with Mass Save partners ✅ We help apply for HEAT Loan financing if it makes sense

    We are not a Mass Save partner ourselves but we work with them constantly on MetroWest projects.

    When to Use Mass Save vs. Standalone Contractor

    Mass Save partner-only services (insulation, weatherization air sealing): Use the Mass Save partner directly. The rebate is much higher when they do the work.

    General renovation that overlaps with Mass Save (kitchen remodel where we open walls; roof replacement where we improve attic insulation): Use us. We coordinate with Mass Save for the energy components.

    Heat pump or HVAC upgrade: We coordinate. The actual HVAC work goes through licensed mechanical contractor; we manage the overall project.

    Free Mass-Save-Aware Project Consultation

    When we walk a renovation, we look at energy efficiency opportunities AS WELL AS your renovation goals. Often there is a rebate-eligible component that improves comfort and saves money long-term.
