HVAC Certification and Licensing in San Antonio

Before seeking a job in the industry, HVAC workers in San Antonio must first obtain the required licensure and certification.

To begin, all workers who handle environmentally sensitive refrigerants must possess EPA Section 608 Certification.

A majority of HVAC programs will prepare graduates for certifying examinations during the course of study.

In addition, several organizations exist that provide skill-based, employment-ready national certifications. A handful of these organizations and their sample certifications are listed below:

  • Refrigeration Service Engineers Society (RSES) – EPA Section 608, commercial air conditioning, dynamic compression, HVAC-R electrical, etc.
  • North American Technician Excellence (NATE) – air distribution, heat pump [air-to-air], hydronics gas, commercial refrigeration, light commercial refrigeration, etc.
  • HVAC Excellence – Heating, Electrical, Air conditioning Technology [HEAT], HEAT Plus, residential heat load analysis, green awareness, etc.

To learn about the full array of national credentials, visit the HVAC certifications page.

Finally, HVAC professionals in San Antonio are required to obtain all necessary local licenses before starting to work. HVAC workers in Texas are licensed by the Texas Department of Licensing and Registration (TDLR).

Additionally, any HVAC workers seeking to advertise their services must obtain an Air Conditioning and Refrigeration Contractor License.
