Why Energy Ratings Matter

Your Windows Are Costing You Money

Up to 30% of your home's heating and cooling escapes through poorly insulated windows. Here's what the numbers mean — and what replacing them puts back in your pocket.

U-Factor: Heat Transfer Rate

Measures how quickly heat passes through the window assembly. Our triple-pane design achieves U-0.13–0.19 — far below the ENERGY STAR® requirement of 0.27.

SHGC: Solar Heat Control

Controls solar radiation entering as heat. Our low-E coating reflects infrared while letting in visible light — cool in summer without darkening your rooms.

Argon Gas Fill

Argon between panes conducts heat 34% less efficiently than air — dramatically boosting insulation without adding visible thickness or reducing light transmission.

Warm-Edge Spacer Technology

Foam-based spacers eliminate thermal bridges at frame edges — no cold spots, no condensation, less heat loss around the perimeter where it matters most.

Customer Stories

Over 100+ verified reviews across Google and Yelp — averaging 4.9 out of 5 stars.

"My home is very sound proof now. Cooler summer temperatures, holds heat much better in winter. The windows are way better quality than the big box competition — the appearance is a high end look. My overall experience was a 10."

FAQ

Common Questions

Everything homeowners typically want to know before they decide.

How long does installation take?
Most homes are completed in a single day. Larger projects (10+ windows) typically take 1–2 days. Our crew handles all prep, installation, and cleanup — you don't need to do anything.
What does the limited double-lifetime warranty cover?
The warranty covers the glass seal against failure (fogging), the vinyl frame and sash against defects in materials or workmanship, and labor for any warranty repair visit. It is fully transferable to the next homeowner.
Do you offer financing?
Ask your Tesla Windows sales representative about 0% financing for up to 18 months during your free in-home consultation. Financing approval and terms depend on your personal credit profile.
How do I know which window type is right for my home?
Our in-home specialist will walk you through each option based on your opening sizes, ventilation needs, and budget. You can also compare styles using our online product guide.
Can I get a quote without a home visit?
Yes — our 60-second online tool gives you a ballpark range instantly. For a binding price, we'll need to measure your openings in person at your free in-home appointment.
Are your windows really ENERGY STAR certified?
Yes. We install Anlin energy-efficient windows that are independently tested and rated by the NFRC and designed to meet or exceed applicable Title 24 and ENERGY STAR® standards.
Do you pull permits and handle HOA approval?
We handle permit applications in all jurisdictions where permits are required. For HOA approvals, we provide documentation packets and material samples to support your submission.
What happens if a seal fails or glass breaks after installation?
A failed seal (fogging between panes) or accidental glass breakage is covered under warranty at no cost to you. We'll schedule a service visit, replace the affected unit, and handle the installation.
What affects my final price — and how accurate is the online estimate?
Our online estimate is designed to give you a helpful ballpark range for your project. The final price depends on the number of windows or doors, each opening's exact measurements, your chosen product style, installation conditions, any structural work needed, and upgrades you select — such as sound-reduction glass, tempered glass, grids, frame colors, or premium hardware. Your free in-home measurement locks in the exact price.
I've been meaning to replace my windows for years. When's the right time?
Every month you wait is another month of higher energy bills. At $420/yr average savings, a year of delay costs roughly $35/month. The second best time is now — especially with 10% off installation labor through May 31.
How do you compare to window programs from Home Depot or Lowe's?
Our customers frequently get estimates from both before choosing Tesla Windows. What they find: our pricing is comparable or lower, our triple-pane products exceed what big-box programs offer as standard, and — unlike retail programs — we handle permits and HOA paperwork in-house. You work with one team from estimate to warranty claim.
