In San Tan, summer temperatures often reach extremes that push your home’s windows to their limit. When older glass lets in too much heat, cooling your home becomes a constant struggle. L.J. Neal & Sons provides heat stopping window and patio door replacement designed specifically for Arizona’s demanding conditions, featuring our L&S windows that are tailored for optimal performance in local climates.
Our Extreme Series triple pane windows are built locally and engineered for desert performance. They help reduce solar heat, block UV rays, and stabilize indoor temperatures so your home stays cooler and more comfortable year-round.
For more than seventy years, homeowners have trusted our team for expert craftsmanship and honest service. From San Tan Heights to Johnson Ranch, families throughout the area choose our Arizona-made products, including L&S windows, for their proven performance and lasting value.

Homes in San Tan face unrelenting sunlight for most of the year. Standard dual pane windows allow that heat to pass directly through, raising energy costs and creating hot spots throughout the home.
Our Extreme Series triple pane windows solve this with three layers of insulated glass and low emissivity coatings that block up to 98 percent of UV and infrared energy. These coatings let in natural light while reflecting heat away from your home.
Every window is manufactured right here in Arizona using materials tested in the same climate you live in. From Copper Basin to Skyline Ranch, our systems provide real comfort, quiet, and energy efficiency.
You will notice cooler rooms, lower energy bills, and less fading on furniture and floors caused by the sun.
Sliding patio doors are beautiful but can quickly become the weakest link in your home’s insulation. At L&S Windows, our triple pane patio doors provide the same advanced protection as our windows, sealing out the desert heat while keeping cool air inside.
Our certified installers take precise measurements to ensure a perfect fit and complete sealing around the frame. The difference is immediate and measurable. Homeowners often report lower indoor temperatures and improved energy efficiency within the first month.
From Hunt Highway to Bella Vista Road, San Tan homeowners trust our team at L&S Windows for patio door replacements that look great and perform even better.


Every product from L.J. Neal & Sons is manufactured locally by skilled Arizona workers. Supporting our company means supporting local jobs, communities, and the pride of producing windows made for this environment.
Each unit is tested for performance in high heat, dust, and monsoon humidity. These are not generic products imported from other climates. They are Arizona engineered, built to last, and proven to perform where you live.
