HVAC Jobs in San Antonio, TX

Texas summers are brutal — triple-digit heat drives some of the highest residential AC replacement rates in the country. Houston, Dallas, San Antonio, and Austin are all large markets where contractors run split-system and package-unit installs year-round, not just seasonally. Demand for service technicians stays elevated even in mild months because the sheer size of the install base means constant maintenance and emergency call volume.

Texas HVAC contractors are licensed at the state level through the Texas Department of Licensing and Regulation (TDLR). Technicians typically hold an Apprentice Technician, Journeyman, or Master license depending on their experience. EPA 608 certification is a federal requirement for anyone handling refrigerants. NATE certification is highly valued by larger commercial contractors in the DFW and Houston metro areas.
