1 What stands out in Texas for an HVAC contractor What is this?

The things people get wrong or do not expect about Texas, in a few sentences.

  • Your license class sets your insurance minimum. Class A needs $300,000 per claim. Class B, for smaller systems, needs $100,000.
  • Everyone who does HVAC work for you must be registered or certified with TDLR, including helpers. Registration costs $20 and has no exam.
  • After you pass the exam you must send TDLR proof of insurance, or a waiver saying you will not do work for the public.
  • Workers' comp is optional in Texas. If you go without it you must tell the state you have opted out.
  • Anyone who handles refrigerant also needs the federal EPA Section 608 card. Texas does not issue it; the state license is separate.
