What Cape Cod homeowners can claim
Cape Cod is a region, not a single city — it covers towns across Barnstable County. Eversource delivers electricity here, but Cape Light Compact runs the Mass Save electric efficiency programs for Cape Cod and Martha's Vineyard. Rebate amounts match the rest of Massachusetts; you apply and book assessments through Cape Light Compact. All amounts below are in US dollars.
Heat Pump (whole-home)
Requires R-32 or R-454B refrigerant. R-410A systems no longer qualify as of January 1, 2026.
Heat Pump (partial-home)
For a heat pump covering part of the home.
Heat Pump (basic)
R-32 or R-454B refrigerant only.
Heat Pump Water Heater
ENERGY STAR certified equipment required.
Insulation
75% covered for all homeowners; 100% for income-qualified households.
Solar (SMART)
SMART program capacity is currently on a waitlist in parts of the state — confirm current status directly with Mass Save.
Battery Storage
Toward a qualifying home battery.
Smart Thermostat
Often installed free during your home energy assessment.
Why Cape Cod is a strong case for heat pumps
Many homes on Cape Cod are older and still heat with oil. Oil heat costs more per unit of heat than a modern heat pump running on electricity, so switching is often one of the strongest financial moves a Cape homeowner can make — on top of the Mass Save rebate itself.
How to claim it
- Schedule your free Mass Save home energy assessment
- Get quotes from Mass Save-participating contractors, and confirm the refrigerant type
- Work is installed
- Contractor or you file the rebate paperwork with Mass Save
- Rebate is paid after Mass Save approves it. Some offers (like heat pump water heaters) are instant; mailed rebates can take months, so keep copies of everything

Renting or living in a condo on Cape Cod? Here's what applies to you
Most of the rebate figures above assume you own a year-round home and control the whole building. If you rent, the structural rebates (heat pump, insulation) go to your landlord, not you. If you own a condo unit in one of the Cape's many condo developments, in-unit upgrades may still qualify with your building's approval, while whole-building work goes through a separate Mass Save multi-unit program. As noted above, seasonal and vacation properties have their own eligibility questions worth confirming directly with Mass Save.
