Examination Process

To become a licensed HVAC contractor, you must pass the Ohio HVAC Contractor exam. The Ohio HVAC licensure exams are provided by PSI Exams. Online practice tests are available to prepare you to be successful when you sit for the actual exam.

It is a lengthy open book exam, with 240 minutes allotted. This portion costs $138.00. The business and law exam for contractors is 120 minutes long and costs $69.00. These fees are a mere drop in the bucket compared to the salary that you will be raking in over the course of your career.

These exams test your knowledge of building codes and HVAC theory as well as your knowledge of repair and installation of HVAC systems. The test should be easy because you will have five years of work experience behind you when you sit for these exams. It is unlikely that you will need a second chance to pass these tests.

Refrigerants are toxic substances that require careful handling by HVAC technicians. EPA Section 608 training is available and will provide the necessary information needed to pass the exam. All HVAC technicians must enroll in the course and pass the exam because handling refrigerants is delicate work. It also requires tons of paperwork! Everything done with refrigerants has to be documented precisely.

Type II certification is for high-pressure appliances, and Type III is for low-pressure appliances. You can earn Universal certification that covers all refrigerants and the required documentation for each.

After extensive work experience, the HVAC technicians can become a contractor and build their own businesses. It is a career path with a multitude of options and job security because conditioned air is always in demand.
