HVAC & Home Performance in Circle C Ranch, Austin

Circle C sits on the limestone hills southwest of Mopac, and the terrain matters more than most homeowners realize. The karst geology means slab foundations shift unevenly, which over time pulls duct boots away from registers and opens gaps in return plenums. Most of the neighborhood went up between 1992 and 2005, built primarily by Centex and Standard Pacific, with 10-SEER equipment and R-30 attic insulation that's now well past its useful life.
