What window rebates pay in Vancouver, Washington
We read Clark Public Utilities' weatherization page on October 6, 2026. The rebates are for electrically heated single-family and manufactured homes. The page lists a U-factor rating, which measures how fast heat leaks through. A lower number is a tighter window.
Windows and patio doors, replacing vinyl frames
The new window must have a U-factor of 0.30 or lower. The old window must have a vinyl frame.
Windows and patio doors, replacing other frames
The new window must have a U-factor of 0.30 or lower. The old window can have any frame type except vinyl.
Best-performing windows
The new window must have a U-factor of 0.22 or lower, whatever the old frame was.
ENERGY STAR insulated exterior door
For doors that meet the ENERGY STAR standard.
Federal tax credit
The IRS says the energy efficient home improvement credit covers improvements made through December 31, 2025.
Working it out
A window of 15 square feet with a rating of 0.22 earns 15 times $10, which is $150. The same window rated 0.28, replacing an old aluminum frame, earns 15 times $8, or $120. Replacing an old vinyl window with a 0.28 unit earns 15 times $6, or $90. Eight such windows could earn between $720 and $1,200. The window sizes here are only examples.
Why the area rule matters
Paying by the square foot means big windows earn more than small ones. A picture window or a patio door brings in more rebate than a small bathroom window, but also costs more. Add up the area of every opening you plan to replace, then multiply by the rate that fits. Ask the installer to list each window's width, height and rating on the bid. The rebate cannot be higher than your cost, so a low-priced job may earn less than the formula says.
Homes this fits
The US Census Bureau's American Community Survey (2020 to 2024) says about 68 percent of homes in Vancouver, Washington use electricity as their main heat, and about 40 percent were built before 1980. About 51 percent of households own. Older electric homes with single-pane or aluminum-framed windows are the likeliest fit. Newer homes already have better windows, and the rebate needs a replacement of an existing one.
Renters make up about 49 percent of households, so many readers will need the landlord to decide. Clark's page does not say whether a landlord can apply for a rental, so call the utility before you plan on it.
Choosing between windows and insulation
Clark's own page says extra insulation makes more financial sense for homes that pay more for fuel. Window replacement is often done for comfort, noise or damage. Compare costs honestly. A rebate of $90 to $150 on a window that costs much more is a small share of the price. If your attic is thin, our Vancouver insulation page may give a better return per dollar.
