Heating Systems covers heating theory, combustion air, vents and chimneys, equipment sizing, heating equipment, installation, hydronics, system operation, troubleshooting, and maintenance.

Open Book Test

The Oklahoma HVACR Journeyman Unlimited examination is an open book test. Candidates may bring approved reference materials into the examination center under PSI testing rules.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. Temporary tabs such as Post-it notes are not allowed, and candidates may not write in the references before or during the examination session.

The highlighted and tabbed books in this rental package support the type of reference navigation needed for open-book preparation. Highlighting can help draw attention to useful provisions, while tabs can make it easier to move between major subjects and sections during study.

An open-book examination still requires strong technical knowledge. Candidates receive 180 minutes for 70 questions, so there is not unlimited time to search every reference for every answer. A better approach is to understand the subject first, identify the appropriate book, and then locate the information needed to confirm or complete the answer.

Mechanical installation, ventilation, ductwork, combustion air, and equipment questions may direct you toward the International Mechanical Code. Natural gas piping, materials, sizing, appliances, combustion air, testing, and venting may require the International Fuel Gas Code.

Modern Refrigeration and Air Conditioning supports broader technical preparation involving refrigeration principles, heating, air conditioning, electrical fundamentals, controls, equipment, system operation, service, maintenance, and troubleshooting. Mathematics for Plumbers and Pipefitters supports trade calculations, while 29 CFR Part 1926 supports construction safety preparation.

A licensed HVACR Unlimited Journeyman works within the scope of the unlimited classification while employed by an HVACR contractor. Candidates should understand both the examination requirements and the role of the journeyman license within Oklahoma's mechanical licensing structure.

State Requirements

Applicants for an Oklahoma mechanical journeyman license must be at least 18 years old and satisfy an approved experience or education-and-experience pathway.

One qualifying pathway requires three years of verifiable experience in the mechanical trade in the category for which the applicant is applying. Oklahoma also recognizes qualifying combinations of approved mechanical education and verifiable trade experience.

The Oklahoma HVACR Unlimited Journeyman classification authorizes the licensee to install, alter, modify, service, maintain, or repair qualifying cooling products, systems, and equipment, including process piping, without the 25-ton cooling limit that applies to the HVACR Limited Journeyman classification.

The Unlimited classification also covers heating equipment, including process piping, without the 500,000 Btu/h per-appliance restriction associated with the limited classification. The scope additionally includes qualifying sheet metal, natural gas piping, and refrigeration work.

Journeymen and contractors are also subject to Oklahoma continuing education requirements. Mechanical licensees are required to complete six hours of continuing education during the 36 months preceding license expiration.

Candidates should view the exam as one part of the complete licensing process. Qualifying experience, proper application, examination approval, testing, and ongoing license requirements all contribute to becoming and remaining an Oklahoma HVACR Unlimited Journeyman.
