Do You Need a License in Ohio to Become an HVAC Technician?

You don't need to have an Ohio HVAC license to work on residential properties. However, you do need a license from the Ohio Construction Industry Licensing Board to work on commercial buildings.

What are the Different Types of HVAC Licenses?

Several types of Ohio HVAC licenses are available. Learn more about each type:

EPA certification is required to work with coolants. You can choose a certification in small appliances, low-pressure coolant, high-pressure coolants, or all three. Because most HVAC contractors will work with coolants, this certification is a must. The average rate of pay is about $22.00 per hour.

NATE certification shows the depth of your knowledge. Being NATE certified could earn you $30 an hour. 

Journeyman working under a Master HVAC technician, and you earn about $19 an hour.

Master HVAC technicians can own a business and hire employees. You can earn $22 an hour unless you gain more certifications.

An HVAC engineer will possess the certifications above in addition to a bachelor’s degree. An engineer can design and build HVAC systems and will earn more than $30 an hour.

The difference between HVAC and refrigeration is the location of the coolants, the coolant circulation, and the mechanisms causing the gases to vaporize.
