EPA Certification Requirements


If you handle refrigerants, you are required by federal law to obtain an EPA certification. This is outlined under Section 608 of the Clean Air Act which states that HVAC technicians who work with refrigerants and any refrigerant-related equipment are required to get the certification, considering that this type of work can release toxic and hazardous chemicals into the surroundings.

To obtain your EPA certification, these are what you should do:


  • Choose your preferred certification type (there are 3 types explained below)
  • Pay a $24.95 certification fee
  • Schedule your examination which can be done either on-site or online
  • Get a passing score to receive your EPA certification


As mentioned, there are 3 types of EPA certifications which are as follows:


  1. Type I – this certification allows you to handle small units and appliances which contain refrigerants not exceeding five pounds.
  2. Type II – a Type II certification lets you handle high and very high-pressure appliances along with split systems and non-automative systems.
  3. Type III – this allows you to deal with low-pressure appliances


You can also choose the Universal certification if you want to handle any appliances from all previous certifications.

It is highly recommended to use the 12-page manual when preparing for the exam. The examination for Type I certification is open book. However, you should get a passing score of 84% or more. Also, the core questions should be repeated in a proctored environment if you want to obtain other certification types. It’s advised to look for a nearby testing center then take a proctored exam for your first examination.
