Heat pumps can efficiently heat your home in the winter and double as a cooling system in the summer - while lowering greenhouse gas emissions.

Ground Source Heat Pumps

Install ground source heat pumps as your primary source of heating and receive rebates up to $15,000 from the Sponsors of Mass Save®.

  • Whole-home rebates are available to customers who install heat pumps as the sole source of heating and cooling. See the Whole-Home Heat Pump Verification Form for details.
  • Partial-home rebates are offered based on equipment size (tonnage) to customers who install heat pumps in a section of their home.  

Ensuring a home has received sufficient weatherization is the best first step in any heating and cooling project. This is a requirement for whole-home rebates and may qualify customers pursuing partial-home rebates for an additional $500 bonus. To schedule an on-site or virtual Home Energy Assessment, call 1-866-527-SAVE (7283).
