Local homes
San Antonio housing and HVAC
Central AC with gas or electric heat is standard, and heat pumps are common in newer homes. Historic homes in King William and Monte Vista may have limited duct space and older equipment. Attic ducts in newer subdivisions face high summer attic temperatures.
Summers are hot and often humid, with highs regularly near or above 100°F. Winters are mild, with occasional freezes. Spring brings severe storms and hail.
Permits and seasonal timing in San Antonio
The City of San Antonio's Development Services Department issues mechanical permits inside city limits, and Bexar County suburbs handle their own. With cooling season stretching from April into October, many owners schedule maintenance twice a year: once in early spring and again before a short winter heating season. Fall and winter are the easiest times to book a replacement.
Long cooling season
Systems run many months a year, so annual maintenance and coil cleaning matter.
Older historic homes
Retrofitting central air in historic homes often calls for ductless or high-velocity systems.
Utility programs
CPS Energy, the city-owned utility, has offered efficiency programs; check current offerings before replacing equipment.
Attic heat in newer subdivisions
Newer north- and west-side homes often have air handlers and long duct runs in attics that can exceed 130°F, so duct insulation and sealing make a measurable difference.
