State Requirements

Applicants for an Oklahoma mechanical journeyman license must be at least 18 years old and satisfy one of the qualification pathways established by the Oklahoma Construction Industries Board.

One standard pathway requires three years of verifiable experience in the mechanical trade in the category for which the applicant is applying. Oklahoma defines one year of qualifying mechanical experience as 2,000 hours.

Oklahoma also recognizes approved combinations of mechanical education and field experience. Depending on the number of approved educational hours completed, qualifying mechanical training may satisfy a portion of the experience requirement while the applicant completes the remaining required work experience.

Equivalent verifiable mechanical experience gained through qualifying military service may also be considered. Certain applicants holding current and good-standing out-of-state mechanical licenses may qualify when the applicable Oklahoma requirements are satisfied.

For Oklahoma experience used toward journeyman licensing, applicable apprentice registration requirements must be followed. Candidates should maintain organized records of employers, hours, mechanical categories, and other experience documentation needed during the licensing application process.

The Refrigeration Journeyman classification authorizes the licensee to install, alter, modify, service, maintain, or repair refrigeration products, systems, or equipment, including process piping.

Journeyman licensing and contractor licensing are different levels within Oklahoma's mechanical licensing system. A Refrigeration Journeyman may perform authorized refrigeration work within the applicable licensing structure, while candidates who later pursue Refrigeration Contractor licensing must meet additional contractor-level qualifications.

Oklahoma mechanical journeymen are also subject to continuing-education requirements. Journeymen and contractors are required to complete six hours of approved continuing education within the 36 months preceding license expiration.
