Estimates are modeled from typical Southern Nevada cooling loads and the glass type you selected. Actual savings vary with home size, orientation, insulation, and HVAC condition. Your in-home assessment gives you the real number.
Where the savings actually come from
In Las Vegas the cooling season runs roughly five hard months, and a house with original single-pane aluminum windows is fighting radiant heat through every opening from mid-morning until well after sunset. Those frames conduct, the glass has no meaningful solar control, and the seals on a 1990s builder-grade dual-pane unit are usually long gone.
A desert-rated triple-pane replacement attacks all three: a low solar heat gain coefficient keeps the sun's energy outside, Low-E coatings on multiple surfaces reflect infrared back, and a thermally broken frame stops the conduction path. The result is an air conditioner that cycles less and a house that holds temperature between cycles.
That is why the honest answer to "how much will I save" is a range, and why we would rather measure your home than guess at it. The calculator gets you in the neighborhood. The assessment gets you the number.
Frequently asked questions
How much can new windows really save in Las Vegas?+
Glass is where a desert home leaks the most money — roughly 25-35% of the cooling load moves through windows and glass doors. Replacing single-pane aluminum with desert-rated triple-pane typically recovers a large share of that, and Las Vegas homeowners commonly report cooling costs dropping 20-40%.
How does this calculator work?+
It takes your peak summer bill, multiplies it across the five-month Southern Nevada cooling season, applies the share of that load attributable to glass for the window type you have today, then applies the share a modern triple-pane package typically recovers — scaled to how many of your openings get replaced.
Is the estimate a quote?+
No. It is a savings model, not a price. Savings depend on home size, orientation, insulation, and HVAC condition, and pricing depends on your openings and install method. The free in-home assessment gives you both real numbers, in writing, the same visit.
What makes a window desert-rated?+
Low solar heat gain coefficient, Low-E coatings on multiple glass surfaces, argon or krypton fill, warm-edge spacers, and a thermally broken frame that will not conduct 115-degree heat straight into the house. A window spec'd for Minnesota is solving the opposite problem.
