HVAC Contractor License in Utah: Requirements, Qualifier, Bond and Exams

Yes — statewide, and at the business level.

The Utah Division of Professional Licensing (DOPL) licenses HVAC contracting businesses through the H100 HVAC Contractor license, the class that replaced the S350 specialty classification, and it issues the license to the business entity rather than to the owner or qualifier.

Our research found no individual HVAC technician or journeyman license on DOPL's roster — the only individual HVAC credential it defines is the H100 Qualifier designation — so confirm the current roster with DOPL before relying on that gap.

The individual requirements that do exist, including the gas-work certification, are covered at the end of this page.

The Utah Division of Professional Licensing (DOPL) issues it, under state rule R156-55a.

For HVAC the class is H100 — the HVAC Contractor license — and the rule says an H100 licensee may employ only an H100 Qualifier as its qualifier.

The class transition is grandfathered: any person holding an active S350 license in good standing on January 1, 2026 is deemed to hold the H100 license for the remainder of the licensing period ending November 30, 2027.

New applicants apply as H100.

Only a DOPL-designated H100 Qualifier: the rule does not let an H100 company name a generic contractor qualifier.

The experience route takes 4,000 hours over no more than a five-year period as an employee of one or more licensed contractors classified H100, B100, S350, P200 or P201, with at least 90% of the applicant's work load directly related to HVAC work, under an H100 Qualifier's direct supervision.

The alternate route is a Utah plumber license: a journeyman, master or residential journeyman/master plumber license satisfies the experience requirement instead of the hours.

Whichever route you use, the same person must then pass the Business and Law and Utah HVAC exams described in the next section.

Two exams, plus a course before you apply.

The H100 Qualifier must pass the Utah Contractor Business and Law exam and the Utah HVAC written exam, the latter with a score of at least 70%.

Utah administers contractor exams through Prov — in person at a ProV testing center or online via ExamRoom AI — and allows 3 attempts 30 days apart, with each subsequent retake 180 days apart.

Every contractor also completes a pre-licensure course from ABC, UHBA or AGC of Utah: 25 hours for specialty contractors, which is the HVAC side; general, plumbing and electrical contractors take the 30-hour course.

Our research did not capture exam fees, so check DOPL's exam page before you book.

The insurance minimums sit in the rule: an H100 contractor carries liability coverage of at least $1,000,000 for each incident and $2,000,000 in total, plus workers' compensation — or a Utah Labor Commission waiver where the company has no employees.

On a bond, our research is silent: we did not find a state surety-bond amount for Utah HVAC contractors, and we did not confirm any job-value threshold below which the H100 license would not be required.

Both gaps matter when you bid small jobs, so ask DOPL what applies before you rely on an exemption.

Utah contractor licenses run on a two-year cycle: they expire on November 30 of odd-numbered years, and renewal costs $128.

Each licensing period also carries continuing education — 6 hours of approved CE, of which 3 must be core, and no more than 3 hours may be online.

Our research did not capture the application fee for a new H100 license, so treat it as a separate budget line and confirm the current amount with DOPL.

The route DOPL publishes is endorsement: if you are currently licensed as a contractor in a state, territory or district of the United States, you may qualify for licensure by endorsement.

What our research did not capture is the fine print — whether Utah names partner states, which trade exams endorsement accepts, or what DOPL waives for an endorsed applicant — so ask the division how your home state's license maps to the H100 before you count on it.

Your designated qualifier may still need to meet the H100 Qualifier experience and exam rules above.

Utah runs this on fixed clocks.

When the qualifier leaves, the qualifier and the company must notify DOPL in writing within 10 days, and the licensee then has 60 days from that date to replace the qualifier — or the license can be revoked.

The replacement must meet the same H100 Qualifier standard: the 4,000-hour HVAC experience route or a Utah journeyman, master or residential journeyman/master plumber license, plus the Business and Law and Utah HVAC exams.

Because the 60-day replacement clock starts on a date you do not choose, and missing it can cost the company its license, know who your next qualifier would be long before anyone gives notice.

Your technicians work under the company's license: our research found no individual HVAC technician or journeyman license on DOPL's roster — confirm the current roster with DOPL.

One individual requirement to plan staffing around is gas: work on gas piping, combustion-air vents, exhaust venting or altitude derating of gas appliances requires the Certified Natural Gas Technician certification, even for HVAC workers.

Approved training routes include federal apprenticeships, Utah college apprenticeship programs, trade union apprenticeships, the Rocky Mountain Gas Association (RMGA) and the Home Builders Association of Utah, and trainees pass the RMGA Gas Appliance Installers exam (or an approved equivalent) with at least 80%.

A current Utah journeyman or residential journeyman plumber license counts as documentation of exemption from that certification.
