Where a Texas master HVAC technician license transfers

Texas's highest HVAC credential is the Air Conditioning and Refrigeration Contractor license issued to an individual by TDLR, so it is mapped here to the master level. The license comes in Class A (units of any size) and Class B (cooling up to 25 tons and heating up to 1.5 million Btu/h) with Environmental Air Conditioning, Commercial Refrigeration and Process Cooling or Heating endorsements. A new applicant must be 18, document 48 months of practical ACR experience under a licensed contractor in the past 72 months (or 12 months as a certified technician plus 36 months of experience, with substitutions for HVAC/R degrees, engineering licenses and military training), pay a $115 application fee, pass the PSI exam for each class and endorsement ($74 Class A, $60 Class B, 70% to pass) within one year of filing, and file proof of commercial general liability insurance ($300,000 per occurrence/$600,000 aggregate for Class A; $100,000/$200,000 for Class B). The license is valid one year, renews for $65 and requires 8 hours of continuing education a year; a company must employ a licensed contractor at each permanent location. TDLR has reciprocity agreements with Georgia and South Carolina only; licensees from every other state or municipality apply under TDLR's substantial-equivalence review and may be required to take the Texas exam.
