  • 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.

Ensuring a home has received sufficient weatherization is the best first step in any heating and cooling project. This is a requirement for whole-home rebates and may qualify customers pursuing partial-home rebates for an additional $500 bonus.
