Starting your mechanical contracting career in Oklahoma requires a specific license from the Oklahoma Construction Industries Board (CIB). This guide provides every detail you need to secure your Mechanical Journeyman or Contractor license, covering requirements, fees, exams, and continuing education rules. We will walk you through the official process to ensure your application is accurate and complete.
Do You Need a Mechanical License in Oklahoma?
Yes, anyone performing mechanical work in Oklahoma, including HVAC, refrigeration, and gas piping, must hold a valid license issued by the Oklahoma Construction Industries Board (CIB) or be registered as an apprentice under a licensed contractor. Unlicensed mechanical work is illegal and can result in significant penalties.
The CIB issues two primary license tiers for individuals:
- Mechanical Journeyman: A licensed professional authorized to perform mechanical work under the supervision of a licensed Mechanical Contractor. Journeymen cannot bid on jobs or operate an independent business.
- Mechanical Contractor: A licensed professional authorized to own and operate a mechanical business, bid on projects, pull permits, and employ other journeymen and apprentices.
Types of Oklahoma Mechanical Licenses
The Oklahoma Construction Industries Board (CIB) structures mechanical licenses into two main tiers, with contractors choosing from several specialized categories.
Mechanical Apprentice Registration
This is the entry-level registration for individuals beginning their career in the mechanical trade. Apprentices must work under the direct supervision of a licensed Mechanical Journeyman or Mechanical Contractor.
Mechanical Journeyman License
A Mechanical Journeyman license authorizes you to perform hands-on mechanical work under the employment and supervision of a licensed Mechanical Contractor. This is the first mandatory license level for individuals performing unsupervised work in the trade.
Mechanical Contractor License
A Mechanical Contractor license authorizes you to operate a mechanical business. This includes advertising services, bidding on and entering into contracts for mechanical projects, and employing journeymen and apprentices.
Mechanical Contractor Categories
Contractors must qualify for one or more specific categories that define their legal scope of work. These include:
- HVAC/R Unlimited Contractor: Covers work on any heating, air conditioning, and refrigeration systems, regardless of size or type.

How to Get Your Oklahoma Mechanical License: A Step-by-Step Guide

-
Fulfill Experience Requirements Document your work history meticulously. For a Journeyman license, you need three years of verifiable experience.

- Register for the Exam: Schedule your exam directly with PSI Exams online or by phone. Exam fees are paid directly to PSI.
- Prepare for the Exam: PSI provides a Candidate Information Bulletin that lists the specific reference materials allowed during the open-book exams, such as the International Mechanical Code (IMC) and other relevant codebooks. Contractors must also prepare for the Oklahoma Business and Law exam.
- Exam Day: Arrive at the testing center with valid government-issued identification. Follow all testing center rules regarding personal items and approved reference materials. You will receive your score report immediately after completing the exam.
-
Obtain Required Insurance and Bonding (Contractors Only) Contact an insurance provider that offers services in Oklahoma to secure your $5,000 corporate surety bond and a certificate of insurance for at least $50,000 in commercial general liability coverage. Ensure the documents are correctly formatted as required by the CIB.

Renewing Your Oklahoma Mechanical License
Oklahoma Mechanical Journeyman and Contractor licenses must be renewed periodically according to CIB rules, every three years, and require the completion of continuing education hours to maintain active status.

Licenses are valid for 36 months (three years). The CIB will send a renewal notice before your expiration date.
Continuing Education (CE) Requirements
You must complete approved continuing education hours during each three-year license cycle.
- CE Requirement: Licensees must complete 6 hours of approved continuing education every 36 months for renewal.
You must take courses from a CIB-approved provider. A list of providers can be found on the CIB website.
Renewal Fees
You must submit a renewal application and pay the required renewal fee to the CIB. If not renewed within 30 days of expiration, a late penalty applies:

- Mechanical Journeyman Renewal Fee: $75 (total of $100 if late).
Late Renewals and Reinstatement
If you fail to renew your license on time, you may be subject to late fees. If a license remains expired for an extended period, you may need to re-apply and potentially re-test to have it reinstated.
Does Oklahoma Offer Reciprocity for Mechanical Licenses?
Oklahoma does not have blanket reciprocity agreements for Mechanical Journeyman or Contractor licenses with other states, but the CIB evaluates out-of-state credentials on a case-by-case basis, always requiring the Oklahoma Business and Law exam for Contractor applicants.
If you hold a mechanical license from another state, you can submit your application and proof of licensure and experience to the CIB for review. The board will determine if your previous experience and examinations are equivalent to Oklahoma's standards. Even if your trade exam is waived, all out-of-state contractor applicants must pass the Oklahoma Business and Law exam.
EPA Section 608 Certification for HVAC Work
In addition to your state mechanical license, anyone who works with and handles refrigerants must obtain EPA Section 608 Technician Certification. This is a federal requirement enforced by the U.S. Environmental Protection Agency.
There are four types of certification:
- Type I: For servicing small appliances.
- Type II: For servicing or disposing of high-pressure appliances.
- Type III: For servicing or disposing of low-pressure appliances.
- Universal: For servicing all types of equipment.
Most HVAC professionals obtain the Universal certification. This certification does not expire and is required for purchasing or handling refrigerants nationwide.
Verify an Oklahoma Mechanical License
You can verify the status of any Mechanical Journeyman or Contractor license in Oklahoma by using the official licensee search tool on the Oklahoma CIB website. This is a critical step for consumers hiring a contractor and for businesses verifying the credentials of a potential employee or subcontractor.
