Claiming Your Connecticut Heat Pump Rebates Step by Step

Customers of Eversource and United Illuminating receive $1,500 for each ton, up to a $10,000 maximum, when the system is put in on or after September 1, 2026. System size is commonly given in tons, where a single ton matches a cooling capacity of 12,000 BTU. An integrated control is required unless the new system serves as the primary heater. An integrated control is a device that automatically switches between your old boiler or furnace and your new heat pump.

  1. Use the official installer network to pick a contractor, so your project qualifies for funding.
  2. If electric resistance heat is being replaced, book a virtual inspection before the work starts.
  3. The 1.99% Smart-E Loan rate requires pre-verifying your rebate online, since pre-approval expires after 60 days.
  4. File your claim online or by mail with the final paid invoice before December 31, 2026.
  5. If your home is randomly selected for a follow-up inspection, cooperate, or the payment will be forfeited.

Income-Qualified Offers and Updates on Federal Rebates

Right now, families with moderate or low income can claim extra help with home energy upgrades and water heaters. Half of households earn more than the median income and half earn less, so it marks the midpoint. A heat pump water heater brings buyers $900, while income-verified households receive $1,900 total with a licensed installer. If a family earns below 60% of the state median, which works out to $93,681 for four people, it can get no-cost energy upgrades.

Right now, Connecticut has no access to the separate federal Home Energy Rebates. Awards of $49,732,517 (appliance rebates) and $49,830,560 (whole-home rebates) are being held by the state to help low-income households. Until the final state blueprints win approval from the federal energy department, both programs remain in planning.

Weatherization, Heating Oil, and Rules for Connecticut Utilities

Heating oil or petroleum products are burned by more than one-third of the state's households, the fourth-largest share nationally. Biofuels are required in heating oil by state law, and sealing your air leaks before a heat pump is installed helps lower your winter bills. A Home Energy Solutions assessment can be booked for a $40 copay beginning on April 1, 2026. Technicians do free air sealing for as long as seven hours, and they also provide weatherization services averaging about $1,000 in value. The Connecticut Weatherization Assistance Program also accepts applications from income-eligible households earning under 60% of the state median.

Energize Connecticut electric rebates exclude towns with municipal electric utilities, among them Wallingford, Norwich, Groton, and Bozrah. The state does plan, though, to set aside 5% of future federal rebate money for customers of municipal utilities. The 25C federal tax credit also ended under Public Law 119-21, and it does not apply to installations after December 31, 2025.

Common Questions About Connecticut Heat Pump Rebates

Do any federal tax credits cover heat pumps in 2026?

No, the federal tax credits known as Section 25C and Section 25D cannot be claimed for equipment placed in service in 2026. These credits stopped early on July 4, 2025, when Congress acted, as Internal Revenue Service Fact Sheet FS-2025-05 explains. State utility rebates can instead be paired with a Connecticut Green Bank Smart-E Loan, whose standard rates run from 6.99% to 7.99%.

Can I claim a rebate on a mini-split heat pump system in Connecticut?

Yes, rebates cover ductless and ducted systems that appear on the Energize Connecticut Heat Pump Qualified Product List. $250 per ton, up to $2,500, goes to units serving new additions, unconditioned spaces, cooling only, or replacements for an old heat pump. United Illuminating still lists the older $15,000 figure from July 2024, but incentives combined for 2026 cap at $10,000 per home.

What is the cost of a heat pump installation in Connecticut?

Energize Connecticut puts the average initial cost of a heat pump installation at $5,000 to $25,000 before rebates. A system is expected to run 15 to 20 years, and average lifetime savings for homeowners reach $5,000 to $15,000. You can gather several quotes, and Energize Connecticut offers a free Heat Pump Consultation service to review your house's pricing.

How can I obtain no-cost energy upgrades or get financing for a heat pump?

Free upgrades are available through Community Action Agencies and Home Energy Solutions Income Eligible to households earning no more than 60% of State Median Income. A loan at 0%, ranging from $1,000 to $3,000 and billed through your utility, is open to Home Energy Solutions participants for a heat pump water heater. At checkout in participating Home Depot and Lowe's stores, the $900 rebate for water heaters can also be claimed.
