Contact Ground-Source Heat Pump Installers
We recommend selecting ground-source heat pump installers from the Mass Save Heat Pump Installer Network (HPIN).
Customers of Berkshire Gas, Cape Light Compact, Eversource, Liberty Utilities, National Grid, and Unitil are eligible for Mass Save ground-source heat pump rebates and financing offers, which are accessed by using an HPIN installer.
Customers of Municipal Light Plants (MLPs) can also use installers in the HPIN, though rebates and financing offers will be determined by your MLP.
