San Marcos: Hill Country Meets I-35 Corridor

San Marcos occupies a unique position in Central Texas — the point where the hill country meets the I-35 corridor, where Texas State University brings energy and growth, and where the San Marcos River creates an environment unlike anywhere else in the region. It’s a city that’s growing rapidly while maintaining its distinct character.

If you’re searching for air duct cleaning in San Marcos, TX, you’re dealing with a specific combination of environmental factors: the hill country pollen and limestone dust that come from the west, the increased development and traffic activity along the I-35 corridor, and the elevated humidity that the San Marcos River and Spring Lake contribute to the local microclimate.

Supreme Air Austin has been serving San Marcos and the Hays County area for over 15 years. We make the drive south because San Marcos homeowners deserve the same professional-grade duct cleaning that our Austin customers receive. We bring commercial equipment, experienced technicians, and the thoroughness that has earned us 900+ five-star Google reviews.
