EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified.

Technicians are required to pass an EPA-approved test to earn Section 608 Technician Certification. The tests are specific to the type of equipment the technician seeks to work on. Tests must be administered by an EPA-approved certifying organization. Section 608 Technician Certification credentials do not expire. Core tests taken as an open book exam cannot be used to get your Universal Certification. The core test must be taken as a proctored exam in order to attain Universal Certification. 

EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act define a "technician" as an individual who performs any of the following activities:

  • Attaching and detaching hoses and gauges to and from an appliance to measure pressure within the appliance.
  • Adding refrigerant to or removing refrigerant from an appliance.
  • Any other activity that violates the integrity of a motor vehicle air conditioner (MVAC)-like appliance or small appliance (other than disposal).

Apprentices are exempt from certification requirements provided they are closely and continually supervised by a certified technician.

Types of Certification

EPA has developed four types of certification:

  1. For servicing small appliances (Type I).
  2. For servicing or disposing of high- or very high-pressure appliances, except small appliances and MVACs (Type II).
  3. For servicing or disposing of low-pressure appliances (Type III).
  4. For servicing all types of equipment (Universal).

The tests for each of these certification types cover different topics.
