Rebates and tax credits in Indiana

Money toward an HRV or ERV

Programs that pay toward the unit itself. Some take the money off at the distributor, so ask whether an installer’s price already includes it.

We didn’t find a program in Indiana that names HRVs or ERVs. Your electric and gas utilities are still worth asking: search “[utility] HRV rebate” and “[utility] ERV rebate”.

Federal home energy rebates

Federal money that Indiana runs. HEAR has a category for “insulation, air sealing, and ventilation” worth up to $1,600 for households under 150% of area median income; each state decides what counts as ventilation. ENERGY STAR’s table for HEAR says this category requires ENERGY STAR certification, and ENERGY STAR’s U.S. criteria for ventilation cover fans, not HRVs or ERVs, so ask the program whether an HRV or ERV counts before relying on it. HOMES pays toward whole-home upgrades modeled to save energy.

Air sealing and insulation

These programs are more common than ventilation rebates, and sealing a house is often what makes it need planned fresh air. If a program is sealing yours, ask whether it requires ventilation afterward and whether it pays for it.

State tax credits

We didn’t find a Indiana tax credit for ventilation, air sealing or insulation, and couldn’t confirm there is none.

Low-income help

The federal Weatherization Assistance Program can pay for air sealing, insulation and, where needed, ventilation at no cost to households that qualify by income. In Indiana it’s run by Indiana Housing and Community Development Authority (IHCDA); apply through the Local Service Provider for your county.

Before you sign

1. Don’t start work yet. Many programs need pre-approval, a participating contractor or a test first, and work begun early often can’t qualify.
2. Write down your electric and gas utilities. Rebates usually follow the utility, not the town.
3. Read the conditions: a listed contractor, a qualifying model, your heating fuel, income limits, and install and claim deadlines.
4. Ask each installer whether any discount is already in their price, and who files the paperwork.
5. Get it in writing: each rebate, who applies for it, and what happens to the price if it’s denied.

Worth knowing

• NIPSCO's insulation and air sealing rebates require a Home Energy Assessment in the current program year first, and a licensed insulation contractor (no do-it-yourself). The attic must start at R-11 or less and reach R-38 or more across the whole attic. Air sealing needs a blower door test showing at least a 20% reduction. Apply within 60 days of installation or by December 31, 2026, whichever is first. One of each rebate per address every three years. [s_nipsco_ias]
• Duke Energy's Smart $aver program includes weatherization rebates through a Duke-approved contractor, and Duke offers a free Home Energy House Call assessment. The City of Bloomington page that describes them lists no amounts. [s_bloomington]
• Indiana warns that Energy Saver contractors do not solicit door to door and that rebates are reached only through IndianaEnergySaver.com. Questions go to rebates@oed.in.gov. [s_in_oed]
• In May 2026 the U.S. Department of Energy changed the rules for these federal rebates, and states with running programs had about three months to update them. Indiana's offer may have changed. [s_doe_pn262, s_naseo_faq]
