Ohio HVAC Contractor License: OCILB Application, Exams, and Local Registration
HVAC Is a State-Licensed Trade in Ohio
Heating, ventilation, and air conditioning (HVAC) is one of five commercial specialty trades regulated at the state level by the Ohio Construction Industry Licensing Board (OCILB) under ORC Chapter 4740. If you're performing HVAC installation, alteration, or repair on commercial or multi-family structures subject to the Ohio Building Code, you need an OCILB master license.
Residential-only HVAC work is technically regulated at the local level, but some municipalities require the state commercial credential even for residential projects. Check the ordinance for every jurisdiction you plan to work in before assuming you're exempt.
How to Get the License
Document your experience. You need five years of verified HVAC experience immediately preceding your application. Acceptable proof includes W-2 forms, Schedule C filings, or Schedule K-1 documents. You'll also need one supplementary item: five consecutive years of trade permits, a valid journeyman card, an apprenticeship completion certificate from an Ohio-approved program or the U.S. Department of Labor, or 40 hours of OCILB-approved continuing education completed in the past year.
Submit your application. A completed, notarized OCILB Examination Application goes to the Division of Industrial Compliance in Reynoldsburg, Ohio, along with a $25 application fee.
Complete background checks. Once the board approves your application, you'll undergo BCI (state) and FBI (federal) fingerprint-based checks. These are valid for exactly one year — if your process takes longer, you start over.
Pass the exams. PSI Services administers two computer-based tests: an HVAC trade exam and a business and law exam. The business and law section has 50 open-book questions with a two-hour limit. You need 70% on each. Fees are $69 per exam or $100 for a combined session. Fail and you wait 60 days to retake; after five failures, your eligibility is revoked and you must reapply to the Board.
Secure insurance. At least $500,000 in commercial general liability, with the OCILB listed as certificate holder. The policy must be in the exact name of a single contracting company.
Pay the licensing fee. $25 to the Treasurer, State of Ohio.
License Assignment Rules
OCILB licenses are issued to individuals, not businesses. Once you receive yours, you formally assign it to one contracting company. You cannot assign to multiple entities or use DBA names under a single assignment.
If you leave the company, the assignment terminates immediately. The company gets a 90-day grace period to complete active projects and find a replacement licensee. You can't reassign your license to a new entity for 90 days unless your former employer signs a letter of release.

Local Registration Is Separate
Even with a state OCILB license, you're exempt from local technical exams only. You still must register with, pay fees to, and show insurance proof at the building department of every municipality where you pull permits. Columbus charges $350/year, Cleveland $150 initially, and Cincinnati $131.25.
