Residential Incentives

There are various state and federal incentives for installing heat pumps for heating/cooling and water heating, including rebates, tax credits and interest-free loans. Access to some of these incentives depends on multiple factors, including who supplies your electricity and household income. 

Mass Save Incentives* and HEAT Loan Program 

Mass Save offers residential heat pump rebates of up to $10,000 for air-source heat pumps (ASHPs) and $15,000 for ground-source heat pumps (GSHPs), with additional incentives for low and moderate income households.

Starting in 2023, residential heat pump rebates will be available only for equipment installed by companies who are part of the Mass Save Heat Pump Installer Network (HPIN). To find qualified installers, go to Mass Save “Find a Participating Contractor Near You”. Some installers include an estimate of the Mass Save rebate in their quotes, and some will submit the rebate request on behalf of their customer. To confirm your rebate amount, contact Mass Save directly before you commit to an installation. 

Your electricity or natural gas must be supplied by an investor-owned utility such as Eversource or National Grid to qualify for Mass Save rebates.

New ASHP minimum energy efficiency requirements will go into effect on January 1, 2023. To ease the transition to the new requirements, ASHPs that meet the 2022 requirements and installed in calendar 2023 will continue to be eligible. See 2023 Air Source Heat Pump Minimum Efficiency Requirement.

The Mass Save HEAT Loan Program provides interest-free loans of up to $50,000 for heating system and weatherization upgrades.

*Mass Save Incentives may be available to natural gas customers, please contact Mass Save directly to learn more. 

Municipal Light Plant (MLP) 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: Massachusetts Clean Energy Center for more information on MLP Communities.

Federal Tax Credits

These credits are increasing substantially in 2023 and will remain in effect for at least 10 years under tax changes mandated by the Inflation Reduction Act signed in August, 2022. Check with your tax preparer on all available credits. See IRS Fact Sheet.

  • ASHPs installed after December 31, 2022 may qualify for a tax credit of 30% or a maximum of $2,000.
  • HPWHs installed after December 31, 2022 may qualify for a tax credit of 30% or a maximum of $2,000. This credit and the ASHP credit have a combined maximum of $2,000.
  • GSHPs installed in calendar 2022 may qualify for a 26% credit. The credit increases to 30% for installation in 2023 an will remain at that level for at least 10 years. The credit is based on the total installation cost. 

MA Sales Tax Exemption

According to the Guide on Sales and Use Tax under the topic Sales and Use Tax Exempt Items-Home & Household Items: “Equipment directly related to solar, wind-powered or heat-pump systems (if the system is used as a primary or auxiliary power system for heating or supplying a taxpayer’s principal residence in Massachusetts)” is exempt from Massachusetts sales tax. In our experience, most Massachusetts HVAC installers do not charge sales tax, which is consistent with this exemption.
