Double-hung windows in Santa Cruz, California
Two vertically sliding sashes; both the top and bottom sash open. For Santa Cruz's older housing stock (66.3% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR South-Central zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.
Short answer
Double-hung windows in Santa Cruz typically cost $770–$3,500 installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Is a Double-hung window right for a Santa Cruz home?
Both sashes slide vertically and typically tilt inward for cleaning.
Where it fits:
- Traditional and historic home styles
- Rooms facing walkways, porches, or patios (no outward projection)
- Easy cleaning from inside on upper floors
What to weigh:
- More potential air-leakage paths than hinged styles at equal quality
- Half the opening ventilates at any one time
Double-hung windows and Santa Cruz's climate
Santa Cruz sits in the ENERGY STAR South-Central zone (IECC zone 3C (warm, marine), Santa Cruz County), where the priority is a low SHGC (≤ 0.23) to block solar heat.
Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the South-Central zone, prioritize a well-built unit and low-SHGC glass (≤ 0.23) to offset that.

Rebates & incentives in California
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
California's IRA rebates run through the California Energy Commission. The HEAR-funded HEEHRA program (delivered via TECH Clean California / The Switch Is On) launched for income-eligible households, but Phase I single-family rebates were fully reserved statewide as of early 2026, with a waitlist and a Phase II in design. HOMES funds are being routed into the Equitable Building Decarbonization Direct Install program and a Pay-for-Performance program that were not yet issuing rebates as of mid-2026. Confirm current availability first. See our Santa Cruz guide for the full program list.
