Installers should visit the Installer Resources page

Once your project has received an award letter from MassCEC, your installer can install your air-source heat pump project. Once the system is installed, you can submit your project completion documents and MassCEC will send out the rebate check. Installers typically submit completion documents on the homeowner's behalf. With each project completion, MassCEC asks for: 

  • Project Completion Form
  • Final Paid Invoice
  • Photos of all outdoor and indoor units 
  • Electric Bill (if new construction)
  • Manufacturer start-up sheet (if VRF) 

For more information on the project completion documents, please review the Pilot Manual.

Are there other incentives available for ASHP systems? 

  • Mass Save offers incentives for homeowners who currently heat with oil, propane, or electric resistance. 

Why was this pilot only available to existing homes served by natural gas?

  • The pilot was intended to be complementary to other available incentive programs in the Commonwealth, including Mass Save’s heat pump rebates, which offer generous incentives for oil, propanes, and electric resistance customers. As a result, MassCEC chose to focus on customers who are served by natural gas for this pilot.

The Whole Home Pilot program is one in a suite of MassCEC's Clean Heating and Cooling Programs. MassCEC authorized $48 million in funding to support clean heating and cooling programs. MassCEC's Clean Heating and Cooling Programs are no longer accepting new applications.
