When summer heat rises off the pavement in Tempe, your windows should protect you, not trap the heat inside. L.J. Neal & Sons helps homeowners replace outdated, inefficient windows with L&S windows, which are locally made and designed to provide energy savings that can withstand the Arizona sun.
For more than seventy years, our team has built a reputation as the trusted name in heat stopping windows and patio doors. Our products, including L&S windows, combine proven craftsmanship with advanced technology to deliver comfort, performance, and style. Every Extreme Series triple pane window is manufactured right here in Arizona and built for our unique desert conditions.
From the neighborhoods near Arizona State University to South Tempe and Kiwanis Park, homeowners count on our L&S windows to lower cooling costs and keep every room comfortable all year long.

Tempe homeowners know that ordinary dual pane windows cannot handle our summer climate. As temperatures climb past 110 degrees, those older windows allow heat and UV rays to pass straight through, forcing your air conditioner to work overtime.
Our Extreme Series triple pane windows are engineered for Arizona heat. Three panes of insulated glass, combined with low emissivity coatings, stop up to 98 percent of solar heat transfer. You get cooler rooms, steady indoor temperatures, and significant relief on your energy bill.
Each window is manufactured locally, ensuring quality control and materials built for the desert. Whether your home sits along Rural Road, near Broadway Avenue, or close to The Lakes, our products are made for the same conditions your home faces every day.
The result is more than just comfort. Our windows help preserve your interiors, protect furniture from fading, and add real long term value to your home.
Sliding doors are often the biggest source of heat gain in any Tempe home. If your current patio doors feel warm to the touch, you are losing energy through them. At L&S Windows, our triple pane patio doors utilize the same advanced glass technology as our windows, creating an efficient barrier between the desert air and your living space.
Each installation is handled by trained and certified professionals who seal every frame with precision. Homeowners often notice a temperature drop of several degrees in adjoining rooms immediately after replacement.
From East Baseline Road to Downtown Tempe, our patio door systems from L&S Windows deliver improved comfort and reliable performance throughout the toughest summer months.


Every window and door we install is proudly made in Arizona by skilled local workers. Choosing L.J. Neal & Sons means supporting local families and investing in products designed specifically for our climate.
Our windows are tested under the same conditions they are built for, ensuring durability through extreme heat, monsoon humidity, and constant sun exposure. You can trust that each window is crafted to perform where it matters most, in your home.
