San Antonio summers are long, hot and humid, so air conditioners work hard for much of the year. Attic ductwork bakes in the heat, and the February 2021 winter storm showed how much homes also depend on reliable heating.

Heating and cooling challenges in San Antonio
Long, humid summers
Air conditioners run for months and must remove humidity as well as heat.
Hot attics
Many homes have ducts and air handlers in attics that get extremely hot, which strains equipment.
Winter storms
During the February 2021 winter storm, many heating systems and heat pumps struggled in the extreme cold.
Storms and surges
Spring storms and power surges can damage outdoor units and controls.

Inside the city of San Antonio, larger drywall, electrical and plumbing repairs can require permits from the City of San Antonio Development Services Department. Homes in other cities, such as Alamo Heights, Schertz or New Braunfels, follow the rules of that city or county.
Mold work is regulated across Texas. Larger mold assessment and remediation jobs must be done by companies licensed by the Texas Department of Licensing and Regulation.

San Antonio questions
Do AC contractors need a license in Texas?
Yes. Air conditioning and refrigeration contractors are licensed by the Texas Department of Licensing and Regulation.
Why does my AC struggle with humidity?
An oversized or poorly maintained system may cool quickly but remove too little moisture. A technician can check sizing and airflow.
How long do AC systems last here?
Many systems last around 10 to 15 years, and heavy use can shorten that. Regular maintenance helps them last longer.
Does Sifixit have an office in San Antonio?
No. Sifixit is a referral service. Providers you speak to are independent local businesses that serve the San Antonio area.
How do I choose a reliable AC repair company in San Antonio?
Check that the company is insured and holds any license Texas requires for this work, get the scope and price in writing, and ask who will actually do the job. Be careful with anyone who wants full payment up front or pushes you to sign the same day, which is common after storms. Sifixit connects you with independent local providers, so always check their details before work starts.
What is the best AC unit for the summer heat in San Antonio?
The best unit is one sized correctly for your home, not simply the biggest. Ask for a load calculation (often called Manual J), compare SEER2 efficiency ratings, and ask whether a heat pump suits San Antonio’s winters. Get options and prices in writing. Our AC replacement page explains what to compare.
My AC is blowing warm air. What should I check first?
Check the thermostat is set to cool, replace a dirty filter, and make sure the outdoor unit is running and clear of debris. If it still blows warm, the cause may be low refrigerant or a failed part that needs a technician. See our AC repair page.
