Exam Details

The Oklahoma HVACR Journeyman - Limited Examination is part of the mechanical licensing program overseen by the Oklahoma Construction Industries Board. The examination is administered by PSI and evaluates trade knowledge associated with limited HVACR work.

The examination focuses on refrigeration and air conditioning, electrical controls, air distribution, heating systems, natural gas, and construction safety. These subjects reflect the technical knowledge involved in installing, maintaining, and repairing mechanical systems.

  • Exam Name: Oklahoma HVACR Journeyman - Limited
  • Licensing Authority: Oklahoma Construction Industries Board
  • Testing Provider: PSI
  • Examination Format: Open book
  • Number of Questions: 60
  • Time Allowed: 180 minutes
  • Passing Score: 70%, equivalent to 42 correct answers

The examination evaluates whether candidates understand the systems and procedures used in HVACR work. Preparation should address both the operation of mechanical equipment and the technical codes that govern installations.

Refrigeration and air conditioning study involves compressors, condensers, evaporators, refrigerants, system performance, and troubleshooting. Heating study covers equipment operation, combustion, controls, and ventilation requirements.

Electrical knowledge includes motors, circuits, controls, electrical measurements, and protective devices. Air distribution involves duct systems, airflow, and mechanical ventilation.

Fuel gas and safety topics are also important because HVACR work frequently involves combustion equipment, gas piping, electrical hazards, and construction jobsite responsibilities.

Open Book Test

The Oklahoma HVACR Limited Journeyman examination is an open book test. Candidates may consult authorized reference materials during testing in accordance with PSI examination-room rules.

Open-book testing requires familiarity with the publications rather than simply having them available. Candidates need to interpret technical questions, identify the relevant source, locate applicable requirements, and understand how the information relates to HVACR installation and service.

All five rental references in this package are highlighted and tabbed to support that preparation. Become familiar with chapter headings, indexes, technical tables, definitions, and important sections throughout the books.

The International Mechanical Code addresses mechanical installations, ventilation, exhaust systems, ductwork, and heating equipment. The International Fuel Gas Code covers fuel gas piping, combustion air, appliance venting, and related installation requirements.

Modern Refrigeration and Air Conditioning provides a broader technical foundation for refrigeration cycles, components, electrical controls, heating, and air conditioning systems.

Mathematics for Plumbers and Pipefitters supports calculations and conversions relevant to mechanical construction. OSHA 29 CFR Part 1926 provides information about construction safety requirements and workplace hazards.

Oklahoma's 2024 code transition: The Oklahoma Construction Industries Board introduced updated mechanical and fuel gas codes beginning September 14, 2026. For the HVACR Journeyman - Limited examination, candidates may test under the previous or newly adopted code editions through December 14, 2026. Beginning December 15, 2026, the affected examination uses the newly adopted codes exclusively.

The 2024 mechanical and fuel gas code books included in this package support study under the updated code requirements.

Practice using the highlighted and tabbed references regularly so you can strengthen your familiarity with technical subjects and locate important information efficiently.

Licensing Steps

Obtaining an Oklahoma HVACR Limited Journeyman license involves meeting the applicable requirements of the Oklahoma Construction Industries Board and completing the appropriate examination process.

  1. Identify the Appropriate Classification: Determine whether Oklahoma HVACR Limited Journeyman licensing matches your intended mechanical work.
  2. Review Eligibility: Understand the applicable experience, apprenticeship, training, and qualification requirements.
  3. Prepare Documentation: Organize records and professional information required for your application.
  4. Submit Your Application: Complete the applicable Oklahoma Construction Industries Board application process.
  5. Study HVACR Trade Subjects: Review refrigeration, heating, electrical controls, air distribution, natural gas, and safety.
  6. Practice Reference Navigation: Become familiar with the five highlighted and tabbed rental publications.

  8. Complete the Examination: Take the Oklahoma HVACR Journeyman - Limited examination and meet the passing requirement.
  9. Finalize Licensure: Complete the remaining applicable Board requirements for journeyman licensing.

The journeyman classification differs from a mechanical contractor license. Journeyman licensing concerns qualified trade work, while contractor licensing involves additional business and professional responsibilities.

This package supports preparation for the HVACR Limited Journeyman trade examination using the five listed references.

State Requirements

The Oklahoma Construction Industries Board regulates mechanical licensing and establishes standards for HVACR professionals performing covered work in Oklahoma.

Oklahoma's HVACR Limited Journeyman classification relates to the installation, maintenance, repair, and other authorized work involving heating, air conditioning, refrigeration, ventilation, and associated mechanical systems within the limited scope.

The limited classification addresses systems with cooling capacities of up to 25 tons and heating equipment with heat inputs of up to 500,000 BTU per hour per appliance.

Candidates pursuing journeyman licensing must satisfy the state's applicable professional qualification and examination requirements. The licensing process is administered separately from mechanical contractor business licensing.

Journeyman professionals need a working understanding of mechanical installation codes, equipment operation, troubleshooting, safe construction practices, and the technical responsibilities of their trade.

The five publications in this package address these important areas through mechanical and fuel gas codes, refrigeration and air conditioning instruction, trade mathematics, and construction safety regulations.
