The thing most pages get wrong
CSU's heat pump page lists the $1,500 and $3,000 rebates after 'As a natural gas customer, you may earn', but its 2026 application lists every heat pump rebate for 'Electric or gas' customers. Electric-only customers should ask before assuming they are left out.
The standard heat pump is a dual-fuel setup
For the ENERGY STAR heat pump rebate CSU's rules say the heat pump 'shall be utilized for total cooling and partial heating', with a control that switches to the furnace at a set temperature. The cold-climate rebate lets the gas furnace stay only as backup for extreme cold.
A credit, not a check
CSU issues rebates as a credit on the utility account. Landlords without a CSU account need a landlord agreement on file to receive a check.
