HVAC contractors in Houston, Texas.

Operating as an HVAC contractor in Houston requires compliance with both Texas state licensing through TDLR and local Houston/Harris County permitting requirements. Contractors must hold an Air Conditioning and Refrigeration License for most commercial work and systems over 25,000 BTU, while technicians need individual licenses and EPA certification. The permitting process is straightforward but mandatory for virtually all installations and major repairs, with permits available online and typical approval within a week. Insurance requirements include general liability and workers' compensation, with many projects requiring $1 million coverage limits. The Houston HVAC market is robust with strong demand driving competitive pricing, but contractors must stay current with licensing, permits, and insurance to operate legally and protect their business.
