State License
STATE TDLR Class A/BRequired for all
HVAC contractors operating in San Antonio must navigate a dual-layer regulatory environment. At the state level, the Texas Department of Licensing and Regulation (TDLR) governs professional licensing and refrigerant handling standards. Contractors must ensure their state license is active and that all technicians are properly certified for the specific tasks they perform.
At the local level, the City of San Antonio requires contractors to register their state credentials with the Development Services Department (DSD) before they are authorized to pull permits. Compliance with the International Mechanical Code, as adopted and amended by the City of San Antonio, is mandatory for all installations. Failure to secure permits or pass required inspections can lead to significant project delays and legal liabilities.
