The Oklahoma HVACR Contractor, Limited Examination is administered by PSI for the Oklahoma Construction Industries Board (CIB). It evaluates knowledge of heating, ventilation, air conditioning, refrigeration, electrical controls, natural gas, duct systems, and construction safety.
The examination is divided into six technical categories:
Refrigeration and Air Conditioning Systems is the largest examination category, representing 20 of the 80 questions. Electrical controls, air distribution, and heating systems are also important areas of preparation.
Applicants pursuing mechanical contractor licensing must also satisfy the applicable Oklahoma Mechanical Business and Law Examination requirement. The package includes legal and contractor management references to support this separate area of preparation.
The Oklahoma HVACR Limited Contractor examination is an open book test. Candidates may use authorized reference materials inside the testing center according to PSI examination rules.
Open-book testing requires technical understanding and efficient reference navigation. Candidates need to identify the appropriate code, technical reference, or calculation method while managing the examination time limit.
The examination references include the Ductulator, International Mechanical Code, International Fuel Gas Code, Modern Refrigeration and Air Conditioning, Manual J, Mathematics for Plumbers and Pipefitters, and OSHA construction regulations.
Oklahoma introduced the 2024 International Mechanical Code and International Fuel Gas Code into its licensing examinations beginning September 14, 2026. During the transition period ending December 14, 2026, candidates may test under the previous or newly adopted code editions. Examinations beginning December 15, 2026, use the newly adopted codes.
The 2024 International Mechanical Code and 2024 International Fuel Gas Code included in this package support preparation under the updated code requirements.
PSI permits approved references to be highlighted, underlined, and indexed before testing. Permanent tabs are allowed, while temporary removable tabs and unauthorized additional papers are prohibited.
All 13 rental references are highlighted and tabbed for organized study. Only the references authorized for a particular examination may be used inside its testing room.
Practice locating information about equipment sizing, ventilation, gas piping, electrical controls, refrigeration systems, combustion air, and workplace safety. Familiarity with technical tables, diagrams, code chapters, and indexes is particularly useful during open-book examinations.
Obtaining an Oklahoma HVACR Limited Contractor license involves meeting the qualifications established by the Oklahoma Construction Industries Board, completing the application process, passing required examinations, and satisfying requirements for active contractor status.
The 1 Package supports these activities through technical references, online course access, Application Service, business setup assistance, and Contractor Compliance Guidance.
The Oklahoma Construction Industries Board regulates mechanical contractor licensing and establishes requirements for individuals performing covered HVACR work.
An HVACR Limited Contractor may perform authorized work involving cooling equipment with a capacity of no more than 25 tons, heating equipment with a heat input of no more than 500,000 BTU per hour per appliance, and other work permitted within the limited mechanical classification.
Mechanical contractor applicants must satisfy the applicable journeyman qualifications and obtain an additional year of qualifying mechanical trade experience.
For an active contractor license, Oklahoma also requires proof of appropriate surety bond and liability insurance coverage. Contractors must maintain applicable licensing and business requirements while performing regulated work.
Business formation and mechanical contractor licensing are separate responsibilities. Establishing an LLC or corporation creates a legal business entity, while the mechanical contractor license authorizes work within the approved classification.
The included business setup services and compliance guidance help customers organize these responsibilities while preparing for their examinations.
