Technical training may substitute for up to two of the four years. Source: Utah Code 58-55-302.
Exam
Administered by Prometric at Utah test centers. Candidates take (1) the S350 (or S351/S354/S355) trade exam and (2) the Utah Business and Law exam. The trade exam covers HVAC system design, installation, service, refrigerant handling, and Utah-specific code and law. Verify current exam fees and passing score in the Prometric Utah Contractor Candidate Information Bulletin.
EPA 608
Any technician handling refrigerant must also hold an EPA Section 608 certification (Type I, II, III, or Universal) under 40 CFR Part 82 Subpart F. EPA states that Section 608 credentials do not expire. Source: EPA Section 608 (https://www.epa.gov/section608/section-608-technician-certification).
Bonding and Insurance
Utah contractor licensees are not required to post a general-purpose license bond under state law. Proof of active Utah workers' compensation insurance (where employees are hired) and general liability insurance at the level required by Utah Administrative Code R156-55a-308a is required at application and renewal. Verify current insurance minimums on DOPL's contractor application page.
Renewal and CE
DOPL contractor licenses renew biennially on November 30 of even-numbered years, under Utah Code 58-55-303. Utah requires 6 hours of continuing education each two-year cycle for contractor licensees, with at least 3 hours in the "core" category (law, rule, business) and up to 3 hours in professional topics, per Utah Administrative Code R156-55a-303b. Confirm current CE structure on DOPL's Contracting renewal page before relying.
Reciprocity
Utah does not publish broad trade-exam reciprocity for HVAC contractors. Out-of-state applicants are evaluated on an endorsement basis under Utah Code 58-1-302. Confirm directly with DOPL before relying on a prior-state license.
