Rebates are based on whether the heat pump system will serve the whole-home or partial-home.
Whole-home rebates are available to customers who install heat pumps as the sole source of heating and cooling. See the Whole-Home Heat Pump Verification Form for details.
Partial-home rebates are offered based on equipment size (tonnage) to customers who install heat pumps in a section of their home.
