Indiana smart-home rebates 2026

What rebate stack actually exists in Indiana in 2026?

Cold-winter dominant

Indiana has 3 actively-funded smart-home rebate programs in 2026, distributed across 3 primary utilities: AES Indiana / Duke Energy IN / I&M, Duke Energy Indiana, AES Indiana Power$aver Home. Indiana has one of the heaviest heating burdens in the country — roughly 60-70% of an average household's annual energy spend goes toward heating between October and April. That single fact reshapes which rebates pay off here: cold-climate heat pumps, attic and wall insulation, and weatherization rebates do the heaviest lifting on your utility bill, while air-source heat-pump conversion (replacing oil, propane, or older electric resistance heat) is the highest-dollar single program category in Indiana in 2026. The strongest categories in Indiana this year are Smart thermostat, Heat pump / mini-split, Insulation / weatherization. Every dollar listed on this page is verified against the utility's own program page as of Q2 2026, and we re-audit quarterly.

HEEHRA in Indiana: what you can claim today

HEEHRA is not yet redeemable in Indiana. The state energy office is finalizing rollout, which historically takes 6-12 months from federal funding receipt to first claims. Federal 25C and 25D tax credits are still claimable today (file IRS Form 5695 with your annual return), and several utility-level rebates listed above can be claimed regardless of HEEHRA status. If you're income-qualified and considering a major heat-pump conversion, it can be worth waiting until HEEHRA opens in Indiana to capture the full stack — but the trade-off is your existing equipment may fail before then.

Worked example: stacking federal + state + utility in Indiana

Here's how a real Indiana heat-pump rebate stack works in 2026. Say you're replacing a 15-year-old furnace and central AC with a 3-ton air-source heat pump rated for cold-climate operation. Equipment + installed labor lands around $14,000-$18,000 in Indiana. Your stack: Duke Energy Indiana rebate of $300, plus the federal 25C tax credit of $2,000 (claimed on your 2026 return via IRS Form 5695). Total stack: approximately $2,300. That brings out-of-pocket on a $16,000 install down to roughly $13,700 after all credits and rebates clear. Always confirm current rebate amounts with the utility before signing a contract — programs can pause mid-year when annual funding allocations are exhausted.

The five common mistakes that kill Indiana rebate claims

Every rebate program has paperwork friction, and most rejected claims fall into one of these five buckets — worth scanning before you commit to a contractor in Indiana.

1. 1Buying equipment before applying. Most Indiana utility rebates require pre-approval — the program needs to see the proposal/quote, not just the receipt.
2. 2Assuming income eligibility without confirming. HEEHRA tiers are tied to Area Median Income for your specific county; check the HUD AMI lookup tool before you assume you qualify (or assume you don't).
3. 3Skipping the energy audit. Several Indiana programs require a utility-approved energy audit as a precondition — the audit itself is often free or rebated, and unlocks 20-40% more in downstream rebate eligibility.
4. 4Using equipment not on the qualified-products list. AHRI and ENERGY STAR certification numbers are what utility staff check first. Even a top-tier model from a brand-name installer can get rejected if the model wasn't on the QPL the day you bought it.
5. 5Forgetting to claim federal alongside utility. The federal 25C credit and most state/utility rebates explicitly stack — they don't reduce each other's eligibility. A surprising number of households claim one and forget the other.
