Ohio HVAC technician license requirements
The answer
Ohio has no state HVAC technician license — technicians train on the job or through apprenticeships, and LOCAL building departments regulate residential work. The state credential is the OCILB HVAC Contractor ('master') license for commercial work: 5 years as a tradesperson, a PSI exam, and liability insurance. EPA 608 is federally required for refrigerant work.Your paths to the license
5 years in the trade → contractor exam
Work as an hvac tradesperson (apprenticeship or OJT) for at least 5 years immediately before applying, then file with the hvac specialty section and pass the PSI exam. Contractor liability insurance is required.
Registered engineer route
A currently registered Ohio engineer with 3 years of construction-industry business experience in the trade may sit the exam instead of the 5-year tradesperson requirement.
Residential / local licensing
Residential contractors are regulated by LOCAL building and health departments (ORC 4740) — many Ohio cities register residential electrical contractors; some require the state license. Check your municipality.
Licensed in another state
The board's 'other experience acceptable to the specialty section' clause (ORC 4740.06(B)(3)) is the route for out-of-state licensees — your documented experience is reviewed case-by-case. Ohio masters also enjoy reciprocity INTO several states (e.g. Texas, North Carolina, Kentucky, West Virginia).
