Additional Details

We offer ground source (geothermal) heat pump rebates based on equipment capacity (tonnage). To pick the right heat pump for your home, consult with a qualified contractor that participates in the Energize CT Heat Pump Installer Network. Select a system that meets our minimum efficiency criteria and claim your rebate once the installation is complete.

How to get started

Check Eligibility

  • Rebates are available to commercial and industrial electric service customers. All commercial and industrial customers of Eversource or UI can participate.
  • Equipment must be installed in the service territory of the participating utility.

For additional energy optimization rebates:

  • Equipment must be installed by a contractor participating in the Energize CT Heat Pump Installer Network.
  • Equipment must replace oil, propane, natural gas, or electric baseboard as the primary heating system.
  • For Eversource customers, rebate amount will not exceed 100% of the total installation cost. For United Illuminating customers, rebate amount will not exceed 75% of the total installation cost.

Technical Details

  • Equipment must be AHRI rated and must meet the minimum requirements on the measure list.
  • Tonnage is based on AHRI cooling capacity. (1 ton = 12,000 BTUs). Tonnage is calculated by dividing AHRI cooling capacity by ton and rounding to two decimal places.
  • The qualifying EER and BTUs are based on the equipment’s Ground-Loop Heat Pump “GLHP” ratings listed by AHRI regardless of the install type

  • Projects totaling between 30 and 150 tons are eligible for rebate tiers found here: C&I Heat Pump Rebate Tier Chart
  • Projects totaling greater than 150 tons will be evaluated independent of this prescriptive rebate format and a custom rebate will be applied
