Double-hung windows in San Jose, California
Two vertically sliding sashes; both the top and bottom sash open. For San Jose's older housing stock (60.8% 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 San Jose typically cost $775–$3,515 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 San Jose 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 San Jose's climate
San Jose sits in the ENERGY STAR South-Central zone (IECC zone 3C (warm, marine), Santa Clara 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.

What Double-hung windows cost in San Jose
Double-hung window replacement in San Jose runs $775–$3,515 installed. 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. San Jose is a high-cost market driven by Bay Area labor rates and high home values, not by extreme custom historic fabrication alone (though older neighborhoods still produce nonstandard openings). Title 24 compliance and quality low-E packages add to the sticker; full-frame work on deteriorated aluminum or wood openings costs more than clean inserts into sound frames. The offset is long ownership horizons and high property values — a competent envelope upgrade is often a small fraction of home equity. With the federal 25C credit expired and PG&E offering no reliable standalone window rebate, budget without counting on incentives; get multiple itemized bids that state NFRC U-factor and SHGC for the exact units quoted.

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 San Jose guide for the full program list.
