How Much Does the Connecticut Rebate Pay?

What you get back depends on what the heat pump takes over. Rebates are figured per ton, which measures the unit's size. A ton equals 12,000 BTU of cooling capacity, and you can find that number on the label the manufacturer gives the unit.

What you install	Rebate	Who	Conditions
Energy Optimization: air source or air-to-water heat pump replacing natural gas, oil, propane or electric resistance	$1,500 per ton up to $10,000 (installs on or after Sept 1, 2026)	Any income	Full displacement or integration with a qualified integrated control; Jan 1-Aug 31, 2026 installs were $1,000/ton with enhanced $1,500/ton for income-based or electric resistance
Standard air source heat pump (replacing a heat pump, unconditioned space, no integrated control, or cooling only)	$250/ton up to $2,500	Any income	On the Energize CT Heat Pump Qualified Product List
Income-based enhanced Energy Optimization incentive	$1,500 per ton, up to $10,000	Income-qualified	Household income above 60% SMI and below 80% AMI, verified via the Energize CT Income-Verification portal (relevant to Apr 1-Aug 31, 2026 installs; from Sept 1 all qualifying installs get up to $1,500/ton)
ENERGY STAR heat pump water heater	$900 for qualifying units	Any income	Integrated >= 3.40 UEF (120V/15A >= 2.20); split >= 2.20 UEF; on the HPWH QPL
Income-eligible enhanced installation incentive	Enhanced incentive of $1,000 (up to $1,900 total)	Income-qualified	Income verified via Energize CT portal; licensed contractor; installed on or after June 1, 2026

For the bigger rebate, the heat pump needs to fully replace your old heating system or operate alongside it using a qualified integrated control. Electric resistance heat means the type that warms a room with hot metal coils, baseboard heaters being a common example.

From January 1 to August 31, 2026, installs earned $1,000 per ton. In that same window, households earning above 60% of State Median Income but under 80% of Area Median Income, along with anyone switching away from electric resistance heat, got $1,500 per ton. Starting September 1, every qualifying install qualifies for up to $1,500 per ton.

No home can receive more than $10,000 in combined incentives. United Illuminating's website references a $15,000 maximum dating to July 2024, but the offer Energize CT currently runs is what counts.

A typical heat pump installation runs $5,000 to $25,000 before rebates, according to Energize CT.

What Does Energize CT Offer and Who Qualifies?

Main heat replacement: $1,500 per ton, capped at $10,000 Standard rebate: $250 per ton, capped at $2,500 Heat pump water heater: $900, or as much as $1,900 based on your income Deadline: Installs must be done by December 31, 2026

Energize CT is the brand name Connecticut uses for its energy efficiency work. Eversource and United Illuminating run it together with the state's energy agency and its Energy Efficiency Board. Applications for the heat pump rebate are being accepted right now.

Eligibility is simple: Eversource or United Illuminating supplies your home's electricity, and the equipment goes into a home in that utility's area. If you get your power from a town utility in Wallingford, Norwich, Groton, or Bozrah, this program does not cover you, and we did not look into those towns' programs.

You'll need an installer from Energize CT's Heat Pump Installer Network. The heat pump itself, along with any control used alongside it, needs to appear on Energize CT's list of qualified heat pump products.

Steps to Claim Your Rebate

Pick an installer who belongs to the network of vetted Energize CT heat pump installers. You can book a free consultation about your heat pump at no charge.
Switching away from electric resistance heat? A virtual inspection must confirm it before the work starts.
You may also pre-verify the rebate online and see whether enhanced incentives apply. You need pre-verification for the Smart-E special rate, and it lasts 60 days or until the end of the year.
Have the heat pump installed.
Submit your rebate claim online or by mail with your final paid invoice.

Energize CT picks some projects at random for an inspection. If yours is chosen, keep the appointment, because missing it means losing the rebate.

Other Ways to Cut Your Costs

A few other offers can trim your out-of-pocket cost.

Smart-E Loan: Eligible heat pump installs qualify for rates as low as 1.99% through December 31, 2026, and pre-verification is required. Otherwise the standard rate falls between 6.99% and 7.99%.
Home Energy Solutions assessment: Starting April 1, 2026, the copay is $40, and the services included typically add up to roughly $1,000.
Income Eligible services: Free for households below 60% of State Median Income. For a four-person household, the cutoff is $93,681.
Heat pump water heater: A qualifying ENERGY STAR unit earns $900. If your income is verified and a licensed contractor installs it on or after June 1, 2026, you can get another $1,000, for up to $1,900 total.

You can get the water heater rebate instantly at Lowe's and Home Depot locations that take part, through a contractor, or after you buy by filing through Energize CT's online rebate portal.

Federal Tax Credits and Connecticut's Home Energy Rebates

The federal tax credit for heat pumps (known as 25C) ended for equipment installed after December 31, 2025, so 2026 installs don't qualify. Public Law 119-21, signed on July 4, 2025, ended it early, per the IRS.

Connecticut has its own Home Energy Rebates program, but it is still being planned. Those rebates are not yet available, the state energy department says.

Questions People Often Ask

Are heat pump tax credits still around for 2026?

No. The federal 25C credit does not cover equipment installed after December 31, 2025. For 2026 installs, the Energize CT rebates are the main source of help.

Where do I get the rebate form for my Energize CT heat pump?

You can file a claim online or by mail at the Energize CT rebate page. Keep your final paid invoice handy when you do.

How long is a pre-verification good for?

It lasts 60 days or until the end of the year, whichever comes first.

Does a DIY heat pump install still earn the rebate?

No. The work has to be done by an installer from Energize CT's Heat Pump Installer Network.
