Our Mission

Reduce greenhouse gas emissions by accelerating adoption of energy-efficient heat pumps in Massachusetts homes and buildings.

Did you know...

If your electricity (or natural gas) is supplied by an investor-owned utility such as Eversource or National Grid, you may be eligible for Mass Save incentives: see Mass Save Residential Rebates and Incentives. Some HVAC installers include an estimate of the Mass Save rebate in their heating/cooling system quotes. Some will submit the rebate request on behalf of their customer, while others do not. Either way, it’s advisable to confirm the rebate amount by contacting Mass Save directly.
