Mass Save is a collaborative energy efficiency program sponsored by Massachusetts’ utility companies. It provides residents with no-cost home energy assessments, rebates, and 0% financing for approved efficiency upgrades.

Most Massachusetts residents—including homeowners, renters, and landlords—qualify for a no-cost energy assessment if their home is served by a participating utility such as National Grid, Eversource, or Unitil.

A licensed specialist inspects your home’s insulation, heating and cooling systems, and air sealing. You’ll receive a personalized report with recommended upgrades and available rebates.

Upgrades that reduce energy use—like insulation, air sealing, high-efficiency heating and cooling systems, and smart thermostats—typically qualify for rebates covering up to 100% of costs.

Savings vary by home, but many residents save hundreds of dollars per year on energy bills. Some upgrades, like insulation, can be discounted or even fully covered.

The HEAT Loan offers 0% interest financing for energy efficiency upgrades. Homeowners can borrow up to $25,000 with repayment terms up to seven years.
