FAQ — Insulation & Air Sealing rebates in Connecticut

How much can I get back on a insulation & air sealing in Connecticut in 2026?

Total potential savings on a $3,800 insulation & air sealing: $1,600. Federal 25C/25D/30C credits are expired and contribute $0; up to $1,600 may come from the income-qualified IRA HEEHRA point-of-sale rebate. Net out-of-pocket: $2,200 (best case) to $3,800 (without HEEHRA).

Is the IRA HEEHRA rebate live in Connecticut right now?

Connecticut HEEHRA status: LIVE. ✓ HEEHRA LIVE — Apply now at your state energy office. If your household income is at or below 150% of your county's Area Median Income (AMI), you qualify for up to $1,600 as an instant point-of-sale discount applied by a participating contractor.

Can I still claim a federal tax credit for this project?

Not for a new 2026 project. The 25C and 25D credits ended for property placed in service after Dec 31, 2025, and the 30C EV-charger credit ended after June 30, 2026. Qualifying 2025 installs may still be claimed on the applicable prior-year IRS form; new installs should budget on gross cost minus state, utility, or HEEHRA incentives only.

Can my Connecticut contractor pad their quote to absorb my rebate?

Yes — this is the single most common abuse in the post-IRA market. The clearest red flag: a quote that's higher than your state's typical range for insulation & air sealing by exactly the amount of the rebate. Always: (1) get the quote BEFORE mentioning rebates, (2) cross-check against Connecticut fair-price data, (3) refuse "rebate handling fees" — HEEHRA point-of-sale is supposed to be applied without additional contractor markup.
