Heat pumps in Connecticut

Connecticut has among the lowest heat pump adoption in the country — 1.7% of homes use one as their main heat — despite expensive heating oil and an aggressive state target. The gap between what the policy wants and what is actually installed is wider here than almost anywhere.

Money and next steps

What Connecticut pays toward one

  • Energize Connecticut

    The statewide initiative run with the utilities and the Connecticut Green Bank. Heat pump rebates, income-qualified programs, and low-interest loans.

  • Federal Home Energy Rebates

    The IRA rebate programs (HEAR and HOMES) survived the 2025 tax changes — they were grants to states, not tax credits. Each state runs its own, and they are at different stages: some open, some already out of money, some yet to launch. Check where Connecticut stands before you count on it.

    Program details →

The federal 25C tax credit — 30% back, up to $2,000 on a heat pump — ended for systems placed in service after 31 December 2025. If you had one installed in 2025 or earlier you can still claim it; there is no successor credit. Incentives move fast, so check DSIRE for what is current in Connecticut.

Cold-climate heat pumps are rated to hold full output well below zero. The question here is not whether one works, it is whether yours was sized and installed for the coldest night of the year rather than the average one.
