Mass Save Air Source Heat Pump Rebates · page 3

Mass Save · Massachusetts, United States · Open

The Mass Save sponsors pay a rebate per ton of cooling capacity, largest when heat pumps replace the home's other heating.

1,592 of the 3,004 certified heat pumps in our data sold in the United States meet the published thresholds for $250–2,650 per ton of Mass Save Air Source Heat Pump Rebates as of Sep 28, 2026.

The program's own qualified product list decides which models it accepts. This page compares the certified figures with the thresholds the program publishes.

Programs change their thresholds. Check the program page before you buy.
