OK HVAC Contractor study guide
OK HVAC Contractor · Work through your exam, one topic at a time.
The Oklahoma Mechanical (HVAC) Contractor credential is issued through the state's Construction Industries Board (CIB), the agency whose stated mission is "to protect life and property by licensing and inspection of the related trades for the health, safety, and welfare of the public." It is aimed at people who perform, or offer to perform, mechanical trade work in Oklahoma - the CIB states plainly that trade licenses/registrations are required for that work, even though general contractors are not currently required to hold a state general contracting license. Candidates should also contact local jurisdictions, since cities and counties may impose their own requirements on top of the state license. The OK HVAC Contractor study guide has 4 sections and about 1,433 words.
01Mechanical (HVAC) Trade Licensing and Inspection
This domain tests the licensing and inspection chain for HVAC/mechanical work in Oklahoma: who may contract for work, when a permit is required, what the authority having jurisdiction (AHJ) inspects, and how approvals are closed out. It is not a design exam, but you must know where the contractor’s responsibility ends and the inspector’s begins.

This domain tests the mechanical code and safety rules that inspectors apply: adopted model codes, combustion air, venting, gas piping, clearances, duct systems and pressure testing. The exam expects code-based reasoning, not rules of thumb.
