ENERGY STAR window replacement for Austin homes — certified products specified for the South-Central climate zone across Travis and Williamson Counties. Call (512) 615-9042 to schedule your window replacement. ENERGY STAR certification for Austin’s climate zone requires U-factor ≤0.30 and SHGC ≤0.25 — specifications that directly address Austin’s heat load.
The Situation
You want to qualify for energy efficiency rebates and lower your cooling bills. Your current windows are original builder-grade units with no Low-E coating and no argon fill. ENERGY STAR certified replacement windows meet the South-Central climate zone specifications that Austin’s climate demands.
Why It Matters in Austin
Texas electricity costs have risen significantly since 2021. Every summer month with underperforming windows costs more in cooling than the same month would with ENERGY STAR certified units.

Common Questions Before You Call
How much will new windows cost?
Window replacement costs in Austin typically run $300–$800 per window installed, depending on size, frame material, and glass type. Whole-house replacement projects range from $4,000 to $20,000+ depending on window count and specifications. We provide written pricing before work begins — no surprises.
Can’t I just have my current windows repaired instead?
If your windows have a single cracked pane or a broken latch, repair may make sense — we recommend contacting your original installer or a glass specialist for repair work. If your windows are fogging between panes, frames are warping, or you’re seeing a pattern of seal failures, replacement is typically more cost-effective than repeated repairs.
How long does window replacement take?
Single window: 1–2 hours. Whole house (10–15 windows): 1–2 days. We install one window at a time so your home is never fully open to the outside at once.
What Austin Homeowners Say
4.8/5 — 241+ Homeowner Reviews
"We had the original aluminum windows from 1968. The difference after replacement is hard to describe — the house feels completely different in summer. No more hot glass, no more condensation on the inside. Worth every dollar."
Robert S.
South Austin
"Our 2004 builder windows all had fogged glass from failed seals. Every single window was cloudy. They replaced all 14 windows in two days. The installers were respectful of the house and left everything clean."
Natalie K.
Cedar Park
"After Uri, one of our aluminum frame windows cracked along the corner. Called and they came out, measured everything, and gave us a written quote before we committed to anything. Installation was clean and fast."
Marcus T.
Round Rock
"We were replacing windows as part of a kitchen remodel. They worked around our contractor’s schedule without complaint. The new Low-E windows make the kitchen noticeably cooler in the afternoon sun."

Frequently Asked Questions
What does ENERGY STAR certification mean for windows?
ENERGY STAR certification means the window product meets EPA energy performance specifications for a specific climate zone. For Austin’s South-Central climate zone (IECC zone 2B), ENERGY STAR requires U-factor ≤0.30 and SHGC ≤0.25. These specs prioritize solar heat rejection — the primary concern in Austin’s climate.
Can I get a rebate for ENERGY STAR windows in Austin?
Austin Energy offers rebate programs for qualifying window replacements. The federal 25C energy efficiency tax credit also applies to ENERGY STAR certified windows. We recommend checking current program availability directly with Austin Energy and your tax advisor — rebate amounts and eligibility requirements change periodically.
Do you repair ENERGY STAR windows?
We specialize in full window replacement and new window installation. For repair of existing windows, we recommend contacting your original installer or a local glass repair specialist.
What is the difference between U-factor and SHGC?
U-factor measures how well a window prevents heat transfer (insulation). Lower is better. SHGC measures how much solar heat the window transmits. Lower SHGC means less solar heat entering the home. For Austin’s climate, low SHGC is the priority — ENERGY STAR requires ≤0.25 for the South-Central zone.
