Do I Qualify
- Use the heat pumps as the primary heating system throughout the heating season.
- Heat pumps must cover at least 80% of peak heating load. Together with permitted supplemental heat, they must cover 100%.
- Use a Residential Registered Vendor. Reserve any furnace or boiler for emergency backup.
- Low- and moderate-income applicants must use the home as their principal residence.
- Homes with a natural gas utility account before the upgrade are excluded. Multi-zone and dual-fuel systems do not earn this rebate.
