HVAC & Home Performance in San Marcos, TX

San Marcos sits at the southern edge of our service area in Hays County, and the housing here reflects two very different markets. Close to Texas State University and the downtown square, you'll find rental duplexes, fourplexes, and single-family homes from the 1950s through 1970s -- many with window units or aging packaged systems, minimal attic insulation, and ductwork that's never been tested for leakage. Landlords and property managers call us when tenants complain about uneven temperatures or high San Marcos Municipal Utility bills, and a duct-leakage test almost always reveals the problem. West of IH-35, newer subdivisions like Kissing Tree and Trace have modern building envelopes, but the Blackland Prairie clay shifts enough that duct connections in attic spaces still need periodic inspection.
