ExploreAbout this exam
The Ohio HVAC Contractor license is the state contractor credential issued by the Ohio Construction Industry Licensing Board (OCILB), which operates within the Department of Commerce's Division of Industrial Compliance. OCILB licenses qualified contractors in the electrical, HVAC, plumbing, hydronics, and refrigeration trades; individuals who meet the Board's qualifications and pass the required licensing examination are issued a state contractor license commonly called a Master License. The credential is aimed at contractors performing commercial HVAC and refrigeration work in Ohio, and it is governed by Ohio Revised Code Chapter 4740, which directs the Board to regulate commercial contractors in these specialty trades to ensure professional competency, public safety, and compliance with state law. State law requires local building and health departments that maintain contractor registration programs to verify state licensure before issuing permits for commercial work; residential regulation stays with local jurisdictions, though locals may require state licensure at their discretion. The HVAC and Refrigeration Section of the 17-member Board reviews license applications, continuing education programs, training agency approvals, and disciplinary matters. Because the Board's HVAC licensing page returned no content when this page was built, exam specifics such as item count, time limit, passing score, fee, retake policy, and license term are not published here. Candidates should confirm those details with the Board office at 614-644-3493 before scheduling. Preparation should combine code and trade fundamentals with a careful read of Chapter 4740 and Board rules.
What you'll study
About OH HVAC Contractor preparation
What does the Ohio HVAC Contractor license actually authorize?
It is the state contractor license, commonly called a Master License, issued by OCILB to individuals who meet Board qualifications and pass the required licensing examination. It covers commercial HVAC and refrigeration contracting regulated under Ohio Revised Code Chapter 4740. Confirm scope questions with the Board office at 614-644-3493.
Who issues the license and where does the Board sit?
The Ohio Construction Industry Licensing Board operates within the Division of Industrial Compliance at the Ohio Department of Commerce. The 17-member Board is organized into the Plumbing and Hydronics, HVAC and Refrigeration, Electrical, and Administrative sections. The HVAC and Refrigeration Section reviews applications, continuing education programs, training agency approvals, and disciplinary matters.
How many questions are on the exam and how long is it?
Not published on the Board page used to build this guide. The HVAC contractor licensing page returned no content at retrieval, so item count, time limit, passing score, and fee cannot be stated reliably. Call the Board office at 614-644-3493 or check the current candidate information bulletin before you schedule.
What score do I need to pass, and what does a retake cost?
Those values are not stated in the available Board source, so treat any number you see elsewhere as unverified. Passing score, retake policy, and fees change periodically. Get them in writing from the Board office at 614-644-3493 before paying for an exam attempt.
Which subjects should I study, and in what order?
The license rests on four bodies of knowledge: HVAC and refrigeration, plumbing and hydronics, electrical, and Ohio Revised Code Chapter 4740 with Board administrative requirements. Start with Chapter 4740 so you understand the regulatory frame, then rotate through the three trade areas, weighting whichever you work in least.
Do I need the state license to pull commercial permits?
State law requires local building and health departments that maintain contractor registration programs to verify state licensure prior to issuing permits for commercial work. Residential contractor regulation remains with local jurisdictions, but those departments may also require state licensure for residential contractors at their discretion.
What is the most common way candidates lose points?
Two patterns dominate: treating the exam as pure trade knowledge and skipping Chapter 4740 and Board administrative requirements, and studying only the trade you work in daily while neglecting the other two. The license spans HVAC and refrigeration, plumbing and hydronics, and electrical, so uneven preparation shows up in the score.
How do I renew, and does continuing education apply?
The Board handles license renewals online and reviews continuing education programs through its sections. Specific renewal cycles, CE hour requirements, and fees are not stated in the source used here, so confirm current requirements with the Board office at 614-644-3493 or the OCILB eLicense Center before your renewal date.
Where can I check a license or file a complaint?
OCILB publishes a current licensee listing for the electrical, HVAC, hydronics, plumbing, and refrigeration trades, and license lookups are available through the OCILB eLicense Center. Commercial complaints must be directed to the OCILB Investigator Supervisor. General licensing, renewal, continuing education, and application questions go to 614-644-3493.
