HVAC is an acronym that stands for heating, ventilation, and air conditioning. It's a field that takes a great amount of learning and preparation, and every state has different requirements for getting an HVAC license. Ohio is no different. In Ohio, getting licensed to work as an HVAC technician takes more time than getting a teaching license at a university. It's no easy road. You need to take classes, work as an apprentice, and then take an exam before you can even start working on your own.
Attend an HVAC school in Ohio. These schools can be found through the web link listed in the "Resources" section below. Classes will give you the training you need to start an apprenticeship.
Become the apprentice of a licensed HVAC technician for 5 years. This will provide you with the hands-on learning that you'll need to become certified yourself. Find apprenticeships through local HVAC union or by visiting local HVAC businesses.
Apply for a license through the Ohio Department of Commerce. Request the application by calling 614-644-3493 or by writing to: Ohio Construction Industry Examining Board, 6606 Tussing Road, P.O. Box 4009, Reynoldsburg, OH 43068-9009. The examining board will review your application and decide whether you are qualified to take the exam.
Study thoroughly for your HVAC exam. Study guides can be found at book stores or your local library. Once you have passed the exam, you will need to pay the required fee before you are officially licensed for HVAC work.
