Aside from the fees, you should be at least 18 years of age before you can submit your application. You should provide proofs and documents that will verify your age and identity. One of them is two 2” x 2” passport size photos which clearly shows your face.

  1. Additional Requirements

If you don’t have your own HVAC business, you should send a notarized employment verification letter with the letterhead of the company you’re working with to the Board. This will serve as verification that you are an employee of that said HVAC business.

Once you have sent your application, it will then be reviewed and verified by the Board of Industrial Trades of the Occupational and Professional Licensing Administration in Washington DC.

EPA Certification


As an HVAC technician, you will receive training when it comes to the proper handling of refrigerants. But in order to do so, you should have an EPA certification first. There are three types of certifications to choose from depending on the type of appliance you want to handle. For small appliances, you can go for Type I certification. For high and very high-pressure appliances, you can choose Type II. For low-pressure appliances, you can opt for Type III certification. Meanwhile, if you want to work on any type of appliance, you can instead go for a Universal certification. This is a national certification and not just a Washington DC HVAC certification.


The Examination Process

Before you can obtain your Washington DC HVAC certification and license, you should first pass the refrigeration and air conditioning examinations. The exams are all open book and all questions are multiple choice.

For the Journeyman Refrigeration and Air Conditioning Exam, you need to answer 60 questions in two hours. The Master Air Conditioning and Refrigeration Mechanical Limited exam comes with 70 questions answerable in three hours. Lastly, the Master Air Conditioning and Refrigeration Mechanical Unlimited exam consists of 80 questions with a 210-minute limit.

The exam you should take will depend on the licensure type you want in the area. The Journeyman examination allows you to obtain a contractor level license. Meanwhile, the Master Air Conditioning and Refrigeration Unlimited exam grants you the Master Mechanic License, and the Master Air Conditioning and Refrigeration Limited exam offers you the Master Mechanic Limited license.

Both Master Mechanic and Master Mechanic Limited license requires at least five years of work experience in the HVAC industry along with a passing score in the exam. However, those who have the limited license can only repair, install, or maintain AC units not exceeding 25 compressor horsepower.

The Master Mechanic examination will test your practical and theoretical knowledge when it comes to the maintenance, installation, replacement, and repair of AC units that have more than 25 compressor horsepower. The exam is supervised by Pearson Vue. If you arrive late during the examination day, your application and examination fees will be forfeited.



You can use a number of reference materials to increase your chances of passing the examinations. Some of them are as follows:

  • The International Mechanical Code by the International Code Council
  • Modern Refrigeration and Air Conditioning by Andrew Althouse, Alfred Bracciano, Carl Turnquist, Daniel Bracciano, and Gloria Bracciano

These reference materials are considered industry-standard. Thus, you should make sure you study and review using these materials before your examination. Despite the examination being open book, you still need to answer the questions within the specified time limit.

While open books are supposed to be easy, you shouldn’t rely on books alone if you want to pass the exams. If you apply for an HVAC certification and license, you should also have hands-on experience and knowledge of the theory.
