MassCEC offered rebates to homeowners who installed qualifying ground-source heat pumps (GSHP), which provide highly efficient electrical heating, cooling, and hot water. This program is part of MassCEC’s Clean Heating and Cooling program, which supports technologies that provide customer cost-savings and environmental benefits while maintaining a high level of comfort and reliability. Due to funding constraints, MassCEC is no longer accepting applications for the Residential Ground-Source Heat Pump projects. 

Installers should visit the Installer Resources page. 

Once your project has received an award letter from MassCEC, your installer can install your ground-source heat pump system. 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 
  • Manufacturer start-up sheet
  • Electric Bill (If new construction) 
  • Invoice (if retrofit project)
