Why Homeowners Call Us

The House Should Work For You, Not Against You

Your energy bill keeps climbing even though nothing else about how you live in the house has changed. Some rooms never quite feel right — too hot in July, drafty in January — and you can put your hand up to the glass and feel exactly why.

A home worth this much shouldn’t be bleeding money out the windows every month. If you’ve already invested in this house, inside and out, the windows should be holding up their end.

The Real Numbers

What Actually Makes a Window Energy Efficient

Efficiency isn’t a marketing word — it’s measurable numbers printed right on the NFRC label that comes with every certified window.

U-Factor
How well the window keeps outside temperature from transferring inside. Lower is better — think of it as the window’s insulation score. It matters year-round, but has more influence on your winter heating load than your summer cooling load.
SHGC
The percentage of the sun’s heat that passes through the glass. Lower is better, and this is the number that matters most in a cooling-dominated climate like DFW. Radiant solar heat through the glass — not air leaking around the frame — is the biggest single driver of your summer AC load.
Low-E Coatings
An ultra-thin, virtually invisible metallic layer that reflects heat while still letting visible light through. It’s the actual mechanism that lowers SHGC without darkening the glass — the difference between a window that just looks clear and one doing real work.

The North Texas takeaway: because DFW summers are long and cooling costs dominate the typical local energy bill, we weight SHGC and Low-E performance heavily when we spec a window here — more than a colder-climate installer would.

Certified for This Climate

ENERGY STAR and What It Means for North Texas

ENERGY STAR certification isn’t one national standard — the program sets different performance requirements by climate zone, because a window that’s efficient in Minnesota isn’t necessarily the right spec for Texas.

DFW falls in ENERGY STAR’s South-Central climate zone, which sets its own U-factor and SHGC thresholds tuned for a hot, cooling-dominated climate — noticeably stricter on SHGC than colder zones.

What that means practically: when we say a window is certified for your home, we mean it’s been tested and verified against the bar for our climate zone, not a generic national baseline. We’ll show you the NFRC label directly, so you’re not taking a sales pitch on faith.

Where We Install Them

Energy Efficient Windows Across DFW

The right glazing spec changes with sun exposure, not city limits — but here’s where we do this most often.

We install energy efficient windows in Fort Worth, Dallas, Flower Mound, Keller, Arlington, and across the rest of the Metroplex. Energy efficient replacement windows are the single most requested upgrade we quote, and in this climate that conversation is mostly about SHGC and Low-E coatings rather than chasing the lowest U-factor on the label.

Straight Numbers

Realistic Savings Expectations

We’d rather tell you a number backed by a real source than one that just sounds good.

According to DOE and ENERGY STAR estimates, replacing old, inefficient windows with ENERGY STAR-certified windows typically lowers a household’s energy bills by roughly 7–15% — the larger end tied to replacing original single-pane windows, the smaller end more typical when replacing older double-pane windows.

Your actual savings depend on your home’s current windows, orientation, shading, insulation, HVAC system, and utility rates — which is exactly why we won’t quote you a specific percentage or dollar figure until we’ve seen your house.

What we can say with confidence: in a cooling-dominated climate like North Texas, upgrading from an aging, high-SHGC window to a modern Low-E, South-Central-rated window is one of the more meaningful things you can do to stop your AC from fighting a losing battle every July and August.

Common Questions

Energy Efficiency FAQ

What do U-factor and SHGC actually mean?
U-factor measures how well a window insulates against outside temperature — lower is better. SHGC (Solar Heat Gain Coefficient) measures how much of the sun’s heat passes through the glass — lower is better. In a hot climate like North Texas, SHGC generally has the bigger impact on your energy bill because solar heat gain drives most of the summer cooling load.
Do energy efficient windows really lower your bill, and by how much?
Yes, on average. DOE and ENERGY STAR estimates put typical savings at roughly 7–15% off household energy bills when replacing old windows with ENERGY STAR-certified windows, with the higher end tied to replacing original single-pane windows. Your actual savings depend on your current windows, sun exposure, and HVAC system, which is why we quote based on an in-home inspection.
Which manufacturers offer the most energy-efficient windows?
All five manufacturers we install — Marvin, ProVia, Andersen, Pella, and Burris — offer ENERGY STAR-qualified, Low-E glazing packages, including higher-performance glass tiers for homeowners who want to prioritize efficiency further. We’ll walk you through the specific options and NFRC ratings for your home during your free inspection.
Are there tax credits or rebates for energy efficient windows?
Federal and utility rebate programs for energy-efficient windows do exist and change from year to year. Ask your tax professional or check current ENERGY STAR federal tax credit guidance for what applies to your situation at the time of purchase.
Is there a best time of year to replace windows for energy savings?
Many North Texas homeowners tackle this before summer, to stop paying for cooled air leaking out during the hottest months, or in fall to shore up the house before heating season. Either works — the more important factor is getting ahead of the season you’re trying to fix, since scheduling fills up seasonally.
How is this different from just picking the most efficient window online?
The most efficient window on paper isn’t always the right spec for your specific home — orientation, shading, and which rooms get direct summer sun all change the calculation. We spec glass packages during a free in-home inspection instead of recommending one generic product for every house.
