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 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.
The install case
A perfect window installed badly leaks and fails. Full-frame replacement with proper flashing beats a cheap pocket insert in a rotted opening — match the install method to your home's condition, not just the price.
The efficiency case
Where winters bite or summers punish, upgrading the glazing — triple-pane or a gas-filled low-E package — returns real money on heating and cooling bills, and ENERGY STAR-rated units can open the door to rebates. Put that upgrade money into the glass before you spend it on a fancier frame.
Vinyl frames are the sensible default unless your situation says otherwise; the glass package is where climate-specific spending pays off. Install quality is the one place a discount always costs more later.
