Florence homeowners know how intense the Arizona heat can be, especially during the summer months when sunlight beats down for hours each day. Outdated or inefficient windows make it even harder to keep your home cool. L.J. Neal & Sons provides heat-stopping window and patio door replacement specifically built for the desert environment, including their renowned L&S windows.
Our Extreme Series triple pane windows are designed, manufactured, and tested in Arizona to ensure maximum performance. They help block heat before it enters your home, lower energy costs, and keep every room more comfortable throughout the year.
With more than seventy years of experience and a strong local presence in Arizona, we bring trusted craftsmanship and reliable service to every installation. From Downtown Florence to Anthem at Merrill Ranch, homeowners count on our team for L&S windows that truly perform.

Homes in Florence experience long hours of sunlight and rapid temperature changes that put ordinary windows to the test. Standard dual pane glass cannot stop the level of UV and infrared heat we face in Arizona.
Our Extreme Series triple pane windows use three insulated glass layers with advanced low emissivity coatings that block up to 98 percent of solar heat. The result is cooler rooms, balanced temperatures, and a more efficient home.
Each window is made right here in Arizona, using materials built to endure the harsh desert climate. From Florence Heights to Magic Ranch, homeowners see immediate improvements in comfort and energy efficiency.
You get natural light without the glare, protection for your interior furnishings, and lasting quality that keeps your home cooler for years to come.
Patio doors bring light and a connection to the outdoors, but they can also introduce unwanted heat. At L&S Windows, our triple pane patio door systems are engineered with the same advanced technology as our windows to effectively stop heat transfer and create a stronger thermal barrier.
Each door from L&S Windows is carefully measured, fitted, and sealed by certified installers who ensure that every edge is airtight. The result is a smooth-operating, beautiful door that keeps your home quiet and comfortable.
From Sun City Anthem at Merrill Ranch to Copper Basin, families in Florence appreciate the difference that our patio door replacements from L&S Windows make in their daily comfort and monthly energy savings.


Every product from L.J. Neal & Sons is built locally by Arizona workers. Choosing our company means supporting local families and receiving windows and doors that are designed for this exact climate.
Our materials and coatings are tested in real desert conditions for durability, insulation, and strength. These are not imported windows made for colder regions. They are Arizona made, built to handle the heat, and proven to last for decades.
Our heat-stopping triple-pane sliding window replacement is ideal for the harsh Arizona climate.
