Climate-zone spec

What window rating you need in Tennessee

Tennessee sits in a mixed climate — the North-Central / South-Central ENERGY STAR window zone. To qualify for ENERGY STAR (v7.0), replacement windows here should meet:

U-factor (insulation)
≤ 0.25–0.28
SHGC (solar heat gain)
≤ 0.40 (North-Central) to ≤ 0.23 (South-Central)

Mixed climates need balance: a low U-factor for winter plus a controlled SHGC so summer sun doesn't overheat the home. Requirements tighten as you move south.

Rebates & incentives

The federal window tax credit is gone for 2026, but ENERGY STAR windows can still earn utility rebates in some areas — and the real long-run savings come from lower heating and cooling bills.

  • The federal 25C tax credit (up to $600/yr for ENERGY STAR Most Efficient windows) ended December 31, 2025 under the One Big Beautiful Bill Act — not available for 2026.
  • Some utilities still rebate high-efficiency windows — real examples include Mass Save (~$75/window on single-pane replacements) and Puget Sound Energy (up to $100/window, more for income-qualified, through 2026).
  • There is no federal HEAR rebate for windows (that program targets electrification equipment like heat pumps), so utility and state programs are the path — check the DSIRE database.
  • The durable savings are on your energy bills: right-rated windows for your climate zone cut heating/cooling costs every year (see the climate-zone spec above).
