Utah to Texas: master HVAC technician license reciprocity

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.

Utah has no master HVAC license. The state credential for HVAC work is the H100 HVAC Contractor classification (formerly S350) issued by DOPL to a business entity or sole proprietorship, not to the technician personally, so a master HVAC licensee from another state who only wants to work for an employer needs no Utah license at all. To contract independently the applicant's business applies for an H100 license with a qualifier who passes the H100 written trade exam and the Utah Business and Law exam (both through Prov), holds a Certified Natural Gas Technician certificate from the Rocky Mountain Gas Association or an equivalent, and documents 4,000 hours of HVAC employment in the past 5 years with W-2, K-1 or tax returns (an active Utah plumber license is an accepted alternative); the qualifier must also complete a 25-hour pre-licensure course and the 5-hour Business and Law course. The business registers with the Division of Corporations, carries general liability insurance of $1 million per occurrence and $2 million aggregate (the March 2026 application form still reads $3 million aggregate) and workers' compensation, and pays $50 per qualifier plus $175 per classification and a $1 surcharge. Utah has no HVAC reciprocity agreements, but DOPL grants licensure by endorsement to a contractor licensed for at least one year in good standing in a jurisdiction DOPL has determined equivalent, with at least 50% common ownership, and an endorsed applicant needs no additional courses or examinations; licenses from other jurisdictions can still be used to document part of the experience and exam requirements.
