• 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 plan to keep an existing boiler or furnace in place to supplement a new heat pump system.
