State License
STATE TDLRRequired for all
HVAC contractors operating in Dallas, Texas, must adhere to a dual-layer regulatory framework. At the state level, the Texas Department of Licensing and Regulation (TDLR) governs professional licensing and refrigerant handling certifications. Contractors must ensure their state license is current and that they carry the mandatory minimum liability insurance coverage.
At the municipal level, the City of Dallas requires contractors to register their state credentials with the Development Services Department before pulling mechanical permits. Compliance involves submitting detailed project plans for major installations, paying applicable permit fees, and passing mandatory inspections to ensure adherence to the International Mechanical Code as adopted by the city.
