TX Builder, Attic Insulation & Air Duct Cleaning Specialist

TX Builder operates from San Antonio and serves surrounding Central Texas communities including Round Rock, San Marcos, New Braunfels, and Buda. The company specializes in attic insulation and air duct cleaning, fields where buildup directly impacts indoor air quality and HVAC efficiency. With a 5-star average across 161 verified client reviews, the business has earned a reputation for thoroughness, technicians routinely photograph problems before and after service, showing homeowners exactly what requires attention.

What distinguishes TX Builder is the combination of specialized attic services alongside ductwork expertise. The company addresses the specific challenges of Central Texas sealed construction, where long cooling cycles during scorching summers trap dust, allergens, and moisture in duct systems. Their air duct cleaning covers supply ducts, returns, vents, and interior surfaces, targeting the buildup that undermines breathing comfort and strains cooling equipment over time. This dual focus allows technicians to connect attic insulation conditions to how air actually moves through the entire system.

Multiple reviewers note technicians arrived promptly, solved problems quickly, and took time to educate homeowners about their systems.
