What is open for Cape Cod homes in 2026
Cape Light Compact is one of the Mass Save sponsors listed for the heat pump rebate, so confirm which sponsor serves your town. Each card names the program page we read on October 3, 2026.
Whole-home heat pump
$2,650 per ton for a whole-home air-source system, up to $8,500, for homes replacing oil, propane or electric resistance heat, or natural gas heat through a gas sponsor. Installed by a Mass Save heat pump installer in 2026.
Income-qualified heat pump
Enhanced rebates for moderate-income and income-eligible households. This is not the standard amount.
Home energy assessment
The no-cost assessment unlocks the weatherization offers.
Decarbonization consultation
A no-cost virtual consultation with a Mass Save Decarbonization Specialist, plus a Heating Comparison Calculator that compares the annual cost of different systems. Useful if you do not know where to start.
Insulation and air sealing
75% is the standard offer. 100% generally applies to income-qualified households or certain buildings with one to four units.
Heat pump water heater
Instant rebate when replacing an electric, oil, propane or gas water heater.
Solar (SMART)
A flat payment per kWh for systems up to 25 kW in National Grid, Eversource and Unitil territory. The state tax credit is 15% of cost, up to $1,000.
Battery
A 5 kW battery enrolled in ConnectedSolutions earns about that over summer events. The HEAT Loan can finance it at 0%, up to $25,000.
Federal credits
The 25C and 25D credits do not apply to 2026 installs.
Homes that are not lived in all year
The 2020-2024 American Community Survey counts 166,215 housing units in Barnstable County and 105,777 occupied households, so roughly a third of homes are not occupied year-round. Mass Save's rules for seasonal and vacation properties are not on the program pages we read, so we cannot say how a second home is treated. If that is your situation, ask Mass Save before you plan around a rebate.
Mostly owners, mostly houses
About 81% of Cape households own and about 82% live in detached houses. Few homes are in two- to four-unit buildings (about 6%), so the landlord-focused rules matter less here than in an inner-city triple-decker. The usual claimant is a homeowner replacing a system.
Gas, oil and propane
The ACS estimates about 61% of occupied Cape homes use utility gas, 19% fuel oil, 13% electricity and about 5% bottled gas. The heat pump rebate is written around what you replace. Oil, propane and electric resistance qualify through the electric sponsor, and gas homes through the gas sponsor. Oil is where the switch tends to save most, because the rebate is paid for replacing it and a heat pump cuts the fuel you buy.
Housing age
About 56% of Cape homes were built before 1980, a lower share than in inner Boston-area cities like Lynn or Salem, and about 13% were built since 2000. The free assessment will tell you whether air sealing or insulation should come before a heat pump is sized.
Check your sponsor
Mass Save's electric sponsors include Eversource, National Grid, Unitil and Cape Light Compact. Municipal light plant towns are separate. Which one applies depends on your address, so confirm it first and then ask the installer to fit the paperwork to that sponsor.
Refrigerant rule
Since January 1, 2026 Mass Save has removed heat pumps with a high-warming refrigerant, including R-410A, from its qualified list. If a contractor quotes one, you will not get the rebate. Ask which refrigerant is in the unit before you sign.
