About the Central San Antonio & Inside Loop 410 area

Central San Antonio and the area inside Loop 410 include downtown-adjacent neighborhoods and the independent cities of Alamo Heights and Terrell Hills (78209), Olmos Park (78212), Castle Hills (78213), Balcones Heights (78201) and Leon Valley (78238 / 78240). This is the oldest housing in the metro, including 1920s-1960s homes, pier-and-beam foundations, and homes that have been renovated several times. Each small city runs its own permitting, separate from the City of San Antonio.

San Antonio has a long cooling season. AC systems run hard from spring into fall, and attic ductwork deals with extreme summer heat, so routine tune-ups, coil cleaning and duct sealing matter more here than in milder climates. CPS Energy serves most of the area; check its current rebate programs before replacing a system. Texas requires air-conditioning and refrigeration contractors to be licensed by TDLR, and you can verify any license number using the TDLR license search.

An independent city on Bandera Road and Huebner Road in the northwest, home to the historic Huebner-Onion Homestead and many 1960s-1980s homes. Systems here are often original replacements from decades ago. Get the age of your condenser and furnace checked before you put money into a major repair.
