Open Book Test

The Oklahoma Refrigeration Contractor examination is an open-book test. Candidates are permitted to use approved references in the examination center while following the applicable testing rules for reference materials.

The approved technical reference list includes the International Mechanical Code, 2018 edition with Oklahoma revisions; Modern Refrigeration and Air Conditioning; and Code of Federal Regulations - 29 CFR Part 1926 (OSHA). Later editions of non-code references are permitted in the test area, while code questions are based on the specifically listed code edition.

That makes the Modern Refrigeration and Air Conditioning, 22nd Edition included with this package suitable for reference preparation under the testing rules for later editions of non-code books.

Approved reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. Temporary tabs, including Post-it notes, are not allowed. References may not contain candidate-added writing before or during the examination session.

The highlighted and tabbed rental books included with this Ultimate package help candidates develop familiarity with the organization of the material during their study period. Candidates should practice finding technical information repeatedly rather than relying on their books only when a practice problem becomes difficult.

A useful open-book approach is to identify the topic first. A question about an electrical relay or compressor may require refrigeration trade knowledge, while a mechanical installation question may direct the candidate to the International Mechanical Code. Safety questions may require 29 CFR Part 1926.

Reference navigation should be practiced under timed conditions. Read the question, determine the subject, select the appropriate book, locate the relevant section, and evaluate the answer choices. Repetition can help make this process more efficient.

Licensing Steps

The Oklahoma Construction Industries Board regulates mechanical contractor licensing, including the Refrigeration Contractor classification. Contractor candidates must satisfy the applicable experience and licensing qualifications before completing the examination and active-license process.

1. Gain qualifying mechanical trade experience. Build verifiable experience in refrigeration or another applicable mechanical category under the licensing requirements governing the work.
2. Meet the applicable journeyman qualifications. Oklahoma mechanical contractor applicants must meet the same basic qualification requirements as mechanical journeyman applicants.
3. Complete additional contractor-level experience. Contractor applicants must have an additional year of qualifying experience in the mechanical trade beyond the journeyman-level requirement.
4. Prepare and submit the licensing application. Assemble the required application and supporting experience documentation for the Oklahoma Construction Industries Board.
5. Receive authorization for testing. The applicable licensing qualifications are reviewed before an applicant proceeds with the examination process.
6. Schedule the required examinations. Approved candidates arrange testing through PSI.
7. Prepare for the Refrigeration Contractor examination. Study electrical controls, refrigerants, piping, refrigeration equipment, system operations, troubleshooting, installation, maintenance, repair, and safety.
8. Prepare for Mechanical Business and Law. Review estimating, project management, contracts, financial responsibilities, labor, workers' compensation, insurance, bonds, payroll, liens, and licensing requirements.
9. Complete the required examinations. Achieve the applicable passing scores required as part of the licensing process.
10. Complete active contractor requirements. Address the bond, insurance, and other applicable requirements needed to activate and maintain the contractor license.

Application Service is included with this Ultimate package to support candidates in organizing the Oklahoma mechanical contractor licensing application process while they continue preparing for the examinations.

State Requirements

Oklahoma mechanical contractor applicants must meet the applicable journeyman qualification requirements and have an additional year of qualifying experience in the mechanical trade.

Mechanical journeyman applicants must be at least 18 years old. One standard qualification pathway requires three years of verifiable experience in the applicable mechanical category. Oklahoma also recognizes approved combinations of mechanical education and field experience as well as certain qualifying military experience and qualifying out-of-state licenses.

For applicable mechanical licensing calculations, one year of verifiable experience equals 2,000 hours. Oklahoma experience that is used toward licensing qualifications must comply with applicable apprentice registration requirements.

The Refrigeration Contractor classification covers the operation, installation, maintenance, repair, fabrication, alteration, and extension of refrigeration systems, including electrical components, piping, refrigerants, and refrigeration components.

After successfully completing the required examinations, an Oklahoma contractor license remains inactive until active contractor requirements are satisfied. Active plumbing, electrical, and mechanical contractors are required to maintain a $5,000 corporate surety bond payable to the Oklahoma Construction Industries Board.

Active mechanical contractors must also provide evidence of at least $50,000 in commercial general liability insurance. Maintaining required bond and insurance coverage is part of keeping the contractor license active.
