Who licenses: Oklahoma Construction Industries Board (CIB)
License types: HVAC/R Unlimited Contractor License, HVAC/R Limited Contractor License, Refrigeration Contractor License, Sheet Metal Contractor License, Natural Gas Piping Contractor License, Process Piping Contractor License, Ground Source Piping Contractor License.
Companies: Under the Mechanical Licensing Act (59 O.S. section 1850.7) no one may engage or offer to engage in mechanical work as a journeyman or contractor without a valid, appropriate license; a mechanical contractor is anyone who plans, contracts for, supervises or furnishes labor or materials for mechanical work.
Local rules: Cities may add their own permit and inspection requirements (not confirmed in detail); air duct cleaning does not require a state license, and homeowners may do minor repairs on their own property.

Search the company on the CIB 'Are They Licensed?' license search and confirm the mechanical contractor license matches the work.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
