According to the Environmental Protection Agency (EPA), the universal certification is administered by the EPA for air conditioning and refrigeration technicians who engage in activities that might reasonably release refrigerants into the environment.
The Clean Air Act (CAA) covered the release of refrigerants that cause ozone depletion in the Earth’s atmosphere. To control the release of chemicals, the CAA established a certification program under the administration of the EPA. This certification program contains four levels of certification, including the universal level of certification.
To become certified at the universal level, a technician must pass the testing requirements for the three specialist levels of EPA certification. The EPA provides three levels of certification: Type I for small appliances, Type II for high pressure appliances and Type III for low pressure appliances.
To become qualified in each of the levels of EPA certification, a technician must pass exams focused on issues such as the depletion of ozone and the Clean Air Act. Other subjects covered for certification exams include the definition of small appliances, refrigerant recovery techniques and safety.
