Air Source
Heat Pump Rebates
Replace or supplement your oil, propane, or electric baseboard system with “Cold Climate” heat pumps.
Huge whole-home rebates (currently up to $8,500) or partial-home rebates to help you transition to clean, efficient electric cooling and heating.
Heat Pump Water Heater Rebates
Switch from a standard electric or gas water tank to a high-efficiency Hybrid Heat Pump Water Heater.
These units can be up to 3x more efficient than standard tanks, and typically qualify for instant or mail-in rebates ($750+).
0% HEAT Loan
Interest-free financing for qualifying energy-efficient home improvements.
Finance up to $25,000 for up to 7 years at 0% interest. This makes even the most advanced systems affordable immediately.

If you keep your old boiler as a backup, Mass Save requires an “Integrated Control” to switch between the two. We are experts at wiring these complex systems.
