Climate-zone spec
What window rating you need in Washington
Washington 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:
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).
