Home Theater Installation Serving San Marcos and Hays County
San Marcos sits at the crossroads of the Texas Hill Country and the booming Austin–San Antonio corridor, making it one of the most dynamic real estate markets in the state. Whether you're in a newer development near Texas State University, a custom home on the Blanco River, or an established neighborhood in Hays County, KZ Audio & Video designs and installs AV systems that match the character and scale of your home.
We've been serving the greater San Marcos area since 2001 — long before the city's explosive growth. We understand the mix of home styles here, from modern new construction builds to Hill Country ranch-style properties, and we tailor every installation accordingly. Our work in Hays County spans dedicated home theater rooms, whole-home audio systems, Dolby Atmos surround sound, smart home automation, and outdoor audio for patios and pool areas.
San Marcos homeowners near the Texas State University area often have specific needs — whether it's a media room that doubles as a home office, a backyard entertainment system for outdoor gatherings, or a full dedicated theater in a bonus room. We've done all of it, and we bring the same level of craftsmanship to every project regardless of scope or budget.
We are based in New Braunfels — just 20 miles south of San Marcos on I-35 — which means fast response times, no travel surcharges, and the ability to be on-site quickly for both initial consultations and any follow-up service. If you're in San Marcos, Wimberley, Kyle, or anywhere in Hays County, we are your local AV installer.
