Heat pumps in Missouri

Missouri sits at 10.5% of homes on a heat pump — roughly midway between the electric-heated South and the gas-heated Midwest, which is a fair description of the state generally. St. Louis swings from a 24°F average low to a 90°F average high across the year.

Money and next steps

What Missouri pays toward one

  • Missouri Division of Energy

    Part of the Department of Natural Resources. Ameren Missouri and Evergy run the substantial residential rebates, including heat pump incentives for homes converting from electric resistance heat.

  • 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 Missouri 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 Missouri. 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.
