Residential Rebates and Incentives

There are a variety of financial incentives for installing a heat pumps for heating/cooling and water heating, including rebates, tax credits and interest-free loans. The details depend on several factors, including who supplies your electricity.

Mass Save Rebates for Utility Customers (Eversource, National Grid)

If your electricity is supplied by an investor-owned utility such as Eversource or National Grid, you may be eligible for a Mass Save rebate: see Mass Save Residential Rebates and Incentives. Some HVAC installers include an estimate of the Mass Save rebate in their heating/cooling system installation proposal and 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. The Mass Save Heat Loan Program provides interest-free loans of up to $25,000 for heating system and weatherization upgrades.

Municipal Light Plant Customers

If your electricity is supplied by a municipal light plant (MLP), check with the MLP to learn about available incentives. Some MLPs provide incentives that are comparable to MassSave rebates.

Federal Tax Credit

For air source heat pumps (ASHP) and heat pump water heaters placed in service in 2021, see Equipment Tax Credits for Primary Residences. Air source heat pumps and heat pump water heaters that meet certain performance requirements qualify for a one-time tax credit of up to $300 each, but not more than $500 for both. For ground source heat pumps (GSHP) placed in service in 2021, see Renewable Energy Tax Credits. The tax credit for the 2021 tax year is 22% of the total installation cost. These credits are currently scheduled to sunset in 2022. Consult your tax adviser to find out if you can benefit from any of these credits.
