Utah licenses HVAC work under H100. It is easy to assume HVAC is a specialty trade classification like roofing or drywall, but DOPL groups H-100 with the general classifications alongside B100 General Building, R100 Residential and Small Commercial, E100 General Engineering, and the electrical and plumbing classifications.
That grouping carries real consequences. General classifications require the qualifier to pass the Utah Contractor Business and Law exam and to show at least two years of paid construction experience, which DOPL expresses as 4,000 hours, or to qualify through an alternative path. General classifications also require the 5-hour Business and Law course on top of the 25-hour pre-licensure course that every contractor applicant completes.
H100 additionally carries its own trade requirements: DOPL asks applicants to pass the H100 written trade exam and to document qualified HVAC employment, which the application describes as 4,000 hours within the past five years, evidenced by W-2, K-1, or tax returns.
On the insurance side the requirements match other classifications: active general liability naming the Division, and either a workers compensation certificate naming DOPL or a Workers Compensation Coverage Waiver from the Utah Labor Commission if there are no employees. Check DOPL’s currently published limits at the source rather than relying on a number quoted elsewhere.
