Idaho Power Heating and Cooling Efficiency Program · page 16

Idaho Power · Idaho and Oregon, United States · Open

Idaho Power pays for a ductless heat pump that replaces electric zonal heat, or a ducted air-source heat pump, in an existing home.

3,004 of the 3,004 certified heat pumps in our data sold in the United States meet the published thresholds for $400–800 of Idaho Power Heating and Cooling Efficiency Program as of Sep 28, 2026.

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