HVAC in San Marcos
Vetter Air — trusted HVAC for San Marcos homeowners.
Spring water rises along the Balcones Fault at San Marcos and feeds a river that has never been recorded running dry, one reason people have lived on this spot for thousands of years. The Hays County seat stands halfway between Austin and San Antonio, is home to Texas State University, and grew from 44,894 residents in 2010 to 67,553 in 2020.
San Marcos uses ZIP codes 78666 and 78667, reaches from Hays County into Caldwell and Guadalupe counties, and lines Interstate 35 from exit 199 to exit 208. The springs at the head of the river form Spring Lake, and Sewell Park, on the Texas State campus, is one of the most popular places in town to get in the water. San Marcos CISD runs most of the city's public schools, with San Marcos High School as its only high school, while Hays CISD's Blanco Vista Elementary sits inside the city limits in the far northeast.
