As of October 10, 2026, we found no window replacement rebate for Orange County homeowners on SCE's or SoCalGas's rebate pages, and the federal window credit has ended. That makes choosing the right window, and sealing your home first, the main ways to get value from a replacement.
So for a 2026 replacement in Orange County, the savings come from the window itself. Here's what the official pages said.
Is There a Window Replacement Rebate in Orange County?
We didn't find one. On October 10, 2026, SCE's marketplace page and SoCalGas's rebates page listed no window rebate. SCE's Energy Savings Assistance page lists window or wall AC replacement, but not window replacement.

Is the Federal Window Tax Credit Still Available?
No. The IRS page for the 25C credit, which ended after December 31, 2025, lists a $600 limit for exterior windows and skylights within its $1,200 annual cap for 2025. IRS Fact Sheet FS-2025-05 says the 25C credit ended for property placed in service after December 31, 2025.
A window installed in 2026 gets no federal credit.
How Do I Choose an Energy-Efficient Replacement Window?
Look for the ENERGY STAR label and the National Fenestration Rating Council (NFRC) label, then compare the U-factor and the solar heat gain coefficient (SHGC). The DOE says to choose a low SHGC in warm climates to reduce heat gain.
The DOE Energy Saver Guide explains that the U-factor is the rate at which a window conducts non-solar heat, and a low SHGC admits less of the sun's heat. For temperate climates with both cold and hot seasons, it suggests windows with both a low U-factor and a low SHGC.
The DOE's window guide says ENERGY STAR qualified windows can save as much as 7% to 15% or more on annual household energy bills, depending on location and the window being replaced.
Should I Do Anything Before Replacing Windows?
Yes. The DOE's window guide says to make sure your home is already properly insulated and air sealed before replacing windows. It also notes that replacing single-pane windows may be cost effective, but exterior storm windows are an alternative.
If your home was built before 1978, the DOE guide warns it likely contains lead paint, so hire installers trained to control lead dust.
