Connecticut offers up to $15,000 in state rebates for qualifying heat pump installations, plus you can claim 30% of the project cost as a federal tax credit (up to $2,000 annually for air-source systems). The exact rebate amount depends on your system size and what you’re replacing.
If you’re replacing oil, propane, natural gas, or electric resistance heating, you qualify for the higher rebate tiers. Eversource customers get $500 per ton for installations between January and May 2025. The rebates require pre-registration and installation by a certified contractor within 60 days of approval.
These incentives can reduce your out-of-pocket costs significantly, but they expire December 31, 2025. The rebate application process takes 30+ days, so starting early protects your eligibility.
