About HVAC in San Antonio

San Antonio's 1991-2020 normals at the international airport show average highs of about 95°F in July and 96°F in August with summer nights near 75°F, while January lows average 41°F, so air conditioning runs most of the year and furnaces or heat pumps are still needed on winter cold fronts. In Texas anyone who installs, repairs or maintains air conditioning, refrigeration or heating systems must hold an Air Conditioning and Refrigeration Contractor license from the Texas Department of Licensing and Regulation (TDLR), issued as Class A or Class B with an environmental and/or commercial refrigeration endorsement. Ranked by license record and years licensed, never by payment. Checked 28 October 2026.
