Heat pumps in Indiana

Indiana has the highest heat pump adoption in the Midwest at 6.8% of homes — more than triple Michigan's rate, in a nearly identical climate. Rural Indiana never got gas mains, went electric, and heat pumps followed. It is a useful reminder that adoption tracks fuel access more than weather.

Money and next steps

What Indiana pays toward one

  • Indiana Office of Energy Development

    Indiana has no statewide residential efficiency program — rebates come from individual utilities such as AES Indiana, CenterPoint and Duke Energy Indiana. The state office is the clearest map of what exists.

  • Federal Home Energy Rebates

    The IRA rebate programs (HEAR and HOMES) survived the 2025 tax changes — they were grants to states, not tax credits. Each state runs its own, and they are at different stages: some open, some already out of money, some yet to launch. Check where Indiana stands before you count on it.

    Program details →

The federal 25C tax credit — 30% back, up to $2,000 on a heat pump — ended for systems placed in service after 31 December 2025. If you had one installed in 2025 or earlier you can still claim it; there is no successor credit. Incentives move fast, so check DSIRE for what is current in Indiana. Last checked September 2026.

Cold-climate heat pumps are rated to hold full output well below zero. The question here is not whether one works, it is whether yours was sized and installed for the coldest night of the year rather than the average one.
