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).

How much should new windows really cost you?
Frame material, glass package and install type decide the price. Our editors on what's worth paying for.
The efficiency case
Extreme climates are the one setting where premium glazing pays for itself over the years: triple-pane and gas-fill packages hold indoor temperatures steadier and trim the utility bill, with rebate eligibility a possible bonus on ENERGY STAR models. Between a better frame and better glass, the glass is where the payback lives.
The install case
The best window on the market still fails when it's set into a bad opening without proper flashing. If the existing frame is rotted, a full-frame replacement that reseals the opening outlasts a cheap pocket insert every time — let the home's condition, not the lowest bid, decide the method.
The value case
Vinyl, double-pane, low-E windows deliver most of the comfort and efficiency for the lowest price. For whole-home replacements on a budget, they're the sensible default.
Buy the glass package your climate needs, default to vinyl frames unless you have a reason not to, and never let install quality be the thing you cut to hit a number.
