San Jose homeowners lose an average of $400 a year to drafty windows, according to Department of Energy estimates — and single-pane glass, still installed in nearly 40% of Santa Clara County homes built before 1990, is the single biggest culprit. That gap between old glass and 2026 efficiency standards is exactly where window replacement rebates step in.
San Jose homeowners qualify for up to $6,500 in combined state and utility rebates for ENERGY STAR-certified window replacement in 2026; federal tax credits no longer apply (IRS FS-2025-05). Income-qualified households can stack additional TECH Clean California incentives.
How Much Can You Save With San Jose Window Replacement Rebates?
San Jose window replacement rebates combine two funding layers: California state programs and PG&E utility incentives, totaling up to $6,500 for qualifying households in 2026; federal tax credits no longer apply (IRS FS-2025-05). Amounts scale with household income and equipment efficiency rating.
Replacing single-pane windows with ENERGY STAR-rated double-pane units costs $600-$1,200 per window installed in San Jose. And a typical 15-window whole-home project runs $9,000-$18,000 before incentives. So a household claiming a $2,500 PG&E rebate cuts out-of-pocket costs by roughly 14-28%. But income-qualified households under TECH Clean California see steeper reductions, sometimes 40% off total project cost. Use a rebate calculator to estimate exact savings based on window count and household income before signing a contractor agreement.
What Windows and Equipment Qualify for the Rebate?
Qualifying equipment includes ENERGY STAR Most Efficient-certified windows with U-factor of 0.27 or lower and Solar Heat Gain Coefficient of 0.25 or lower for the Northern California climate zone. Vinyl, fiberglass, and wood-clad frames all qualify when glass specs meet 2026 program thresholds.
Single-pane replacement glass alone, without frame replacement, doesn't qualify for utility rebates — PG&E requires full unit replacement. Or homeowners can pair window upgrades with heat pump rebates for combined HVAC-and-envelope projects, since many California utility programs bundle building-envelope and equipment incentives into one application.
| Program | Rebate Amount | Eligibility | 2026 Deadline |
|---|---|---|---|
| Federal IRA Tax Credit | Ended Dec 31, 2025 | — | Ended Dec 31, 2025 |
| PG&E Home Energy Rebates | Up to $2,500 | San Jose PG&E customers | Rolling, funds-limited |
| TECH Clean California | Up to $4,000 | Income-qualified households | Rolling, until funds exhausted |
What Are the Income Limits and Eligibility Requirements?
Income-qualified San Jose households — those earning at or below 80% of Area Median Income (roughly $98,000 for a household of four in Santa Clara County) — access the highest rebate tiers, up to $4,000 through TECH Clean California.
Income tier breakdown for Santa Clara County
Households below 80% AMI qualify for maximum rebate stacking. Households between 80-150% AMI receive reduced TECH Clean California amounts. Households above 150% AMI qualify only for standard PG&E rebates, not income-tiered bonuses.So a moderate-income household of four earning $95,000 qualifies for full stacking. And a household earning $180,000 loses access to the $4,000 income-tiered rebate. But every applicant, regardless of income, needs the home to be a primary or secondary residence in Santa Clara County — rental properties follow separate landlord incentive rules under window replacement grants for homeowners.
How Do You Apply and Do You Need a Licensed Contractor?
San Jose window rebate applications require a C-17 or B-licensed California contractor, itemized project invoices, and ENERGY STAR product documentation submitted through the PG&E Marketplace portal or TECH Clean California online system before or immediately after installation.
The application sequence runs: get a licensed-contractor quote, confirm equipment meets 2026 efficiency specs, submit pre-approval where required, complete installation, then file for reimbursement with invoices and product spec sheets. And PG&E requires pre-approval for its rebate tier before work begins. Form 5695 only covers qualifying work completed by December 31, 2025 and claimed on a 2025 return; the federal 25C and 25D credits ended after that date (IRS FS-2025-05). But TECH Clean California processes reimbursement post-installation only. So homeowners skipping licensed-contractor documentation forfeit utility-tier rebates entirely, even if the window product itself qualifies.
Is the Rebate Still Available and What's the Deadline?
San Jose window replacement rebates remain active through 2026, with PG&E/TECH Clean California funds allocated on a rolling, first-come basis that can exhaust before year-end; federal tax credits no longer apply (IRS FS-2025-05).
And PG&E's rebate pool typically depletes by Q3 in high-demand years, so early application matters. The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). Federal tax credits for this work have ended, but state, local and utility rebates may still apply; check what is available at your address with the DuloCore rebate calculator. Or homeowners waiting on state-tier funds risk missing the current allocation cycle entirely. So checking funding status before signing a contractor agreement prevents budget surprises mid-project.
Can You Stack San Jose Window Rebates With Other Programs?
San Jose homeowners stack PG&E utility rebates and TECH Clean California incentives on a single window replacement project, provided total incentives don't exceed the project's actual cost.
And a household replacing windows alongside a heat pump installation combines both projects' rebates into one application cycle. But total incentive value can't exceed 100% of documented project cost — overlapping programs get proportionally reduced if combined amounts exceed spend. Or homeowners pursuing solar plus windows in the same year should sequence applications carefully, since some utility budgets allocate by category. Review the full window replacement rebates guide and related geothermal tax credit stacking rules for multi-upgrade projects.

Frequently Asked Questions
What qualifies for window replacement rebates in San Jose?
ENERGY STAR Most Efficient-certified windows with U-factor 0.27 or lower qualify, installed by a licensed California contractor in a primary or secondary residence. Full-unit replacement is required — glass-only swaps don't qualify for the 2026 PG&E or TECH Clean California rebate tiers.
How much money can you get for replacing windows in San Jose?
San Jose households combine up to $2,500 from PG&E with up to $4,000 from TECH Clean California for income-qualified applicants, totaling as much as $6,500 in 2026 depending on income tier and window count; federal tax credits no longer apply (IRS FS-2025-05).
What is the process for applying for a San Jose window replacement rebate?
Homeowners get a licensed-contractor quote, verify ENERGY STAR specs, submit PG&E pre-approval, complete installation, then file reimbursement with itemized invoices. Form 5695 only covers qualifying work completed by December 31, 2025 and claimed on a 2025 return; the federal 25C and 25D credits ended after that date (IRS FS-2025-05).
What are the deadlines for San Jose window replacement rebate applications?
The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). But PG&E and TECH Clean California allocate funds on a rolling basis that historically exhausts by Q3 2026, so early application protects access to the full rebate amount.
Are San Jose window replacement rebates better than California state rebates?
San Jose rebates aren't separate from state programs — they're the same TECH Clean California and PG&E funds applied locally. So San Jose homeowners already access the maximum available state-plus-utility combination.
