Major technical subject areas include electrical knowledge and controls, natural gas, air distribution systems, refrigeration and air conditioning, heating systems, and safety.
The Unlimited classification encompasses authorized mechanical work without the cooling-capacity and heating-input restrictions associated with Oklahoma's Limited HVACR classification.
Candidates should prepare for residential and commercial mechanical applications, including equipment operation, installation requirements, technical calculations, and applicable construction codes.
Mechanical contractor applicants also prepare for applicable Business and Law examination requirements. The package includes Oklahoma statutes, administrative regulations, and the NASCLA contractor business guide to support those subjects.
The Oklahoma HVACR Unlimited Contractor examination is an open book test. Candidates may consult authorized reference materials during testing according to PSI examination-room rules.
Open-book testing requires familiarity with technical publications and the ability to locate information efficiently. Candidates must understand the question, identify the relevant reference, interpret its provisions, and apply the information correctly.
The International Mechanical Code and International Fuel Gas Code support preparation involving mechanical equipment, ventilation, gas piping, combustion air, and installation requirements.
Modern Refrigeration and Air Conditioning covers refrigeration principles and HVACR systems, while Manual N addresses commercial heating and cooling load calculations.
The Ductulator supports duct-sizing review, Mathematics for Plumbers and Pipefitters reinforces calculation skills, and OSHA 29 CFR Part 1926 addresses construction safety.
