Katy is the far west edge of our service area, and it’s worth the drive. From Cinco Ranch and Cross Creek Ranch to the historic downtown, Patriot Air Systems installs and repairs residential and light commercial HVAC systems across the Katy area.
Katy’s large two-story homes are a common source of “upstairs never cools” complaints. Zoning, duct balancing, or a second system are all options, and we’ll tell you which one actually fixes it.
