The end of the federal heat pump tax credit didn’t end Connecticut’s heat pump incentives. For qualifying 2026 projects, utility-funded rebates remain available through several paths. The amount depends on the equipment, the system being replaced, and the installation date.
We have served Milford-area homeowners for more than 40 years, guiding them through current incentive rules before they select and schedule a new system.
The Federal Heat Pump Tax Credit Has Ended
The federal Section 25C Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025. A system installed and placed in service during 2026 doesn’t qualify for that federal credit, even if the homeowner is eligible for Connecticut incentives.
Homeowners whose qualifying heat pumps were placed in service on or before December 31, 2025 can still claim the credit on their 2025 federal tax return using IRS Form 5695. Before it ended, Section 25C covered 30% of qualifying installed costs, up to an annual $2,000 limit for heat pumps and heat pump water heaters.
The distinction is simple: the expired federal credit and Connecticut’s utility-funded rebates are separate programs. The federal cutoff doesn’t eliminate every incentive available to Connecticut homeowners.
Connecticut’s 2026 Heat Pump Incentives
Connecticut homeowners have different incentive paths based on the type of system and the equipment it replaces. Capacity is measured in tons, so the incentive is based on equipment properly sized for the home, not simply the largest unit available.
Standard Air Source Incentive
For qualifying residential air source heat pumps installed from January 1 through December 31, 2026, the standard utility rebate is $250 for each ton of capacity. Combined incentives are capped at $2,500. These systems move heat between indoor and outdoor air, providing heating and cooling from the same equipment.
Residential Energy Optimization Incentive
This higher incentive applies to qualifying air source systems that replace natural gas, oil, propane, or electric resistance heating as the primary heat source. Installations completed on or after September 1, 2026 are eligible for $1,500 per ton, with combined incentives up to $10,000. For installations completed from January 1 through August 31, 2026, the incentive was $1,000 for each ton of capacity.
Ground Source Incentive
A ground source heat pump uses underground loops to exchange heat with the earth rather than outdoor air. For 2026, qualifying residential systems that replace oil, propane, natural gas, or electric resistance as the primary heat source are eligible for $1,500 per ton, up to $15,000.
Your Existing System & Installation Date Matter
The highest advertised rebate isn’t automatically available for every home. Your current system, equipment configuration, eligibility, and completion date determine which incentives apply.
Electric baseboard heat is particularly important to identify early. For eligible installations completed on or after April 1, 2026, homeowners replacing these systems or qualifying through an income-based path may receive enhanced incentives of up to $1,500 for each ton of capacity.
The program requires electric resistance replacement to be confirmed through its heat verification process. Visible baseboards alone don’t establish eligibility. Documenting the home’s existing primary heat source before finalizing the project helps prevent an unexpected rebate decision after installation.
Before approving a proposal, ask these questions:
- Which incentive path fits my current heating system?
- What equipment size in tons is being proposed, and how was it determined?
- Does my installation date affect the incentive amount?
- Is any verification required before the work is scheduled?
Plan the Rebate Before Installation
Rebate planning should happen alongside equipment selection, not after installation. Eligibility rules must match the equipment and scope of work, especially when a home has multiple heat sources or uses a ductless system in only part of the house.
We install both ducted and ductless heat pump systems. During a home visit, we review hot and cold spots, past heating concerns, and home measurements. We then prepare a proposal covering equipment options, expected installation time, and applicable rebates.
As an authorized member of the Energize CT Residential Heat Pump Installer Network, we manage the necessary rebate paperwork and confirm that the installation meets program requirements. This gives homeowners a clearer view of the expected incentive before they commit to a system.
Smart-E Financing for Eligible 2026 Projects
Some homeowners pair an approved rebate with financing through the CT Green Bank’s Smart-E Loan. As of November 5, 2026, the heat pump special rate is as low as 1.99% APR for a five-year term up to $25,000. The offer is available from August 1 through December 31, 2026.
The special rate requires an approved Energize CT heat pump rebate first. Loan approval, financing terms, project timing, and incentive eligibility are separate considerations, so review them together before the offer ends.
