The city of 1,479,835 people has a median home build year of 1985, and 42.5% of homes predate 1980. ZIPs such as 78201, 78212 and 78209 are older still, so ductwork is worth inspecting. CPS Energy rebates inside city limits require the permit number.
San Antonio AC repair →Split between Comal and Guadalupe counties and one of the fastest-growing cities in the area, with 40.2% of homes built since 2010. HVAC contractors must register with the city's Building Safety Division, with a certificate of insurance of at least $300,000.

AC repair in Boerne →Mostly newer subdivisions in Guadalupe County, with a median build year of 2002 and 78.4% of homes owner-occupied. Check with the city's Inspections Division about permits and contractor registration before work starts.

AC repair in Universal City →Live Oak's 2026 FAQ says replacing a condenser, air handler or ducts needs a permit, a final inspection and a duct-leakage test when ductwork is replaced. Homestead owners doing their own work may pull their own permit.
AC repair in Live Oak →The oldest housing in the area: the median home was built in 1950 and 74% predate 1980. Older homes may have older ductwork worth inspecting before a new system goes in.
AC repair in Alamo Heights →The same AC replacement can come with different paperwork a few miles apart. In San Antonio the contractor pulls a city mechanical permit, and CPS Energy needs that permit number to pay a rebate inside city limits. New Braunfels, Boerne and Universal City each require contractors to register with the city. Live Oak adds a duct-leakage test when ductwork is replaced. This is general information, not legal advice; the contractor you hire should know the rules where you live.
The age of the house matters too. Inner-ring areas like Alamo Heights and Universal City have far more homes built before 1980 than newer places such as Cibolo or New Braunfels, and older homes may have older ductwork worth inspecting. Everywhere in the area, the heat is the common thread: about 122 days a year reach 90°F at San Antonio International Airport (NOAA 1991–2020 normals).
Requests cover emergency and after-hours AC repair, AC replacement, AC maintenance, furnace and heating repair, heat pumps, mini split installation and duct cleaning and ductwork. Typical prices are in the AC and HVAC cost guide.
