Heat pumps in Illinois

Illinois runs on natural gas, and at 2.4% of homes heating primarily with a heat pump it is near the bottom nationally. Chicago's winters are real but well within cold-climate equipment range — the barrier here is economic, not technical.

Money and next steps

What Illinois pays toward one

  • ComEd and Ameren Illinois

    Utility rebates are what is actually available in Illinois today — ComEd in the north, Ameren downstate. The state's IRA-funded rebates were still pending federal approval in mid-2026 and were not accepting applications.

  • Illinois Energy Office (DCEO)

    The state agency coordinating the federal rebate programs. Worth checking for launch status rather than assuming the money is available.

  • 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 Illinois stands before you count on it.

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 Illinois. Last checked September 2026.

The numbers

What a heat pump here has to cover

  • 19°F

    Coldest month average low

    Chicago · NOAA 1991–2020 normals

  • 85°F

    Warmest month average high

    Chicago · NOAA 1991–2020 normals

Coldest month, average low Warmest month, average high

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.
