HVAC licensing in Ohio

There is no Ohio HVAC worker card to bring — ORC chapter 4740 licenses only CONTRACTORS, in five trades, through the Construction Industry Licensing Board, and only for COMMERCIAL work. The company lane is real and live: OAC 4101:16-2-10 is in force with OCILB reciprocity forms for Alabama, Kentucky, Louisiana, North Carolina, South Carolina, Tennessee and West Virginia — trade exam waived for qualifying holders, the Ohio business-and-law exam never waived. (That rule was once rumored eliminated; it was verified in force at the source, and Ohio's own asset host still serves the Alabama reciprocity application.)

Nothing pending for you as an employed tech. Company-side interim work during an OCILB application was not established.

Contractor-level and demanding: the applicant must have been a tradesperson in the trade for at least five years immediately prior, hold an apprenticeship completion certificate from an Ohio- or USDOL-approved program, and show 40 completed continuing-education hours from an OCILB-approved agency. Your personal floor is EPA 608.

No state apprentice card for HVAC. Ohio- and USDOL-registered apprenticeship programs are the training route — and completion is literally a prerequisite for the contractor license later.

Two-layer, and the split matters: residential (1-to-3-family) is EXCLUDED from the state law and regulated locally, while major cities require the OCILB license as a prerequisite to their own contractor registration for commercial work. Whether any Ohio city licenses individual HVAC workers (the way Toledo cards journeyman electricians) was not checked — ask the city where the job sits.

The OCILB license sits with whoever contracts commercial work. Working 1099 directly for a customer means acting as a contractor under ORC 4740.13 — the license requirement lands on you. On a licensed contractor's payroll, you need nothing personal.
