Don't Leave Money on the Table
If you're planning any HVAC work in 2026 — whether it's a new boiler, AC installation, heat pump, or ductless mini-split — there are significant rebates and tax credits available that can reduce your cost by thousands of dollars.
Here's every program available to Connecticut homeowners in 2026, consolidated in one place.
Federal Tax Credits (IRA / Inflation Reduction Act)
The federal Inflation Reduction Act provides annual tax credits for energy-efficient home improvements through 2032:
| Equipment | Tax Credit | Requirements |
|---|---|---|
| Heat pump (central or mini-split) | 30% of cost, up to $2,000/year | Must meet CEE highest tier or ENERGY STAR Most Efficient |
| Heat pump water heater | 30% of cost, up to $2,000/year | Uniform Energy Factor ≥ 2.2 |
| Central AC | 30% of cost, up to $600/year | SEER2 ≥ 16, EER2 ≥ 12 |
| Gas furnace | 30% of cost, up to $600/year | 97%+ AFUE |
| Gas boiler | 30% of cost, up to $600/year | 95%+ AFUE |
| Insulation / air sealing | 30% of cost, up to $1,200/year | Meets IECC standards |
| Smart thermostat | 30% of cost, up to $150/year | ENERGY STAR certified |
| Electrical panel upgrade | 30% of cost, up to $600/year | 200-amp service for heat pump support |
Important: These are tax credits, not deductions. A $2,000 credit reduces your tax bill by $2,000. You claim them on IRS Form 5695 with your annual tax return. The $2,000 heat pump credit is separate from the $1,200 cap on other improvements — you can claim both in the same year.
Connecticut State Rebates — Energize CT
Connecticut's Energize CT program (administered by Eversource and United Illuminating) offers additional rebates on top of federal credits:
| Equipment | Rebate Amount | Notes |
|---|---|---|
| Air-source heat pump (ducted) | $750 per ton | Must be ENERGY STAR; installed by licensed contractor |
| Ductless mini-split heat pump | $300 – $500 per indoor head | Covers heating + cooling |
| Heat pump water heater | $400 – $750 | Must replace electric resistance or oil |
| High-efficiency gas boiler | $300 – $750 | 95%+ AFUE; some programs require home energy audit |
| High-efficiency gas furnace | $200 – $500 | 95%+ AFUE |
| Smart thermostat | $50 – $100 | ENERGY STAR certified models |
| Insulation | 50% – 75% of cost | After qualifying home energy audit |
| Home energy audit | $50 (reduced from $250+) | Subsidized audit through HES program |
Stack your savings: Federal credits + CT state rebates can be combined. A qualifying heat pump installation could save you $3,000 – $5,000 or more. We help our customers identify every available incentive.
How to Stack the Savings — Real Example
Here's a real scenario for a homeowner in Stamford installing a 3-ton ducted heat pump system:
| Item | Amount |
|---|---|
| Heat pump system (installed) | $12,000 |
| Federal IRA tax credit (30%, capped at $2,000) | -$2,000 |
| Energize CT rebate (3 tons × $750) | -$2,250 |
| Smart thermostat credit (federal) | -$50 |
| Net cost after incentives | $7,700 |
| Savings vs. old oil system (annual) | $1,500 – $2,500 |
That's a 36% discount on the equipment, plus ongoing fuel savings.
Income-Qualified Programs
Lower-income CT households may qualify for even more assistance:
- IRA Home Electrification Rebates — Up to $8,000 for heat pump installation for households under 80% of area median income. Up to $4,000 for 80–150% AMI. (Availability depends on CT's implementation timeline.)
- Operation Fuel — Emergency heating assistance for CT residents in crisis.
- LIHEAP — Federal Low Income Home Energy Assistance Program, administered through CT DSS.
- Weatherization Assistance Program — Free insulation and air sealing for qualifying households.
How to Claim Everything
- Schedule a Home Energy Audit — Through Energize CT's HES program ($50). This qualifies you for insulation rebates and helps identify the best equipment upgrades.
- Get quotes from a licensed contractor — Make sure they specify equipment models and efficiency ratings.
- Apply for Energize CT rebates — Your contractor can submit these or provide the paperwork.
- Keep all receipts — You'll need them for IRS Form 5695.
- File your tax return — Claim the federal credit on Form 5695 with your 2026 return.
Programs Change — Act While They're Available
These incentives won't last forever. Federal IRA credits are authorized through 2032 but could be modified by future legislation. State rebate budgets are allocated annually and can run out. If you're planning HVAC work in the next 1–2 years, 2026 is a strong time to move — the programs are fully funded and well-established.
