Quick answer

In Oklahoma, the state HVAC license for individual HVAC technicians is issued by the Oklahoma Construction Industries Board. The mechanical journeyman license in an HVAC/R category from the Oklahoma Construction Industries Board. The HVAC/R limited license covers cooling equipment up to 25 tons and heating equipment up to 500,000 Btu/h per appliance, plus sheet metal, natural gas piping and refrigeration; the HVAC/R unlimited license has no size limits.

Oklahoma experience counts only while you hold an apprentice registration.

Once the Board approves your application, it forwards your information to its national testing provider, PSI, and you contact PSI to schedule. How to apply: Send the Application for Mechanical Examination with the license fee, payable to the Construction Industries Board; the Board reviews it for approval.
