Heat pumps in Tennessee

Tennessee is fourth in the country at 35.5%, and almost the whole state buys power through TVA — which makes it unusually easy to find out what you qualify for. One programme, one set of rules, whichever local utility sends your bill.

Money and next steps

What Tennessee pays toward one

  • TVA EnergyRight

    TVA runs efficiency programmes across its whole service territory through local power companies, including heat pump incentives and a network of vetted contractors — rare coverage for a Southern state.

  • 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 Tennessee 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 Tennessee. Last checked September 2026.

The numbers

What a heat pump here has to cover

  • 30°F

    Coldest month average low

    Nashville · NOAA 1991–2020 normals

  • 91°F

    Warmest month average high

    Nashville · NOAA 1991–2020 normals

Coldest month, average low Warmest month, average high

Both loads matter here — cold snaps are real, and so are the summers. A system sized only for heating will short-cycle in August; one sized only for cooling will lean on backup heat in January. Getting the balance right is the job.
