As of Nov. 14, 1994, all technicians who handle refrigerants are legally required to obtain a CFC certification, which is an EPA-approved technician's certification that comes in three main types. The certification program trains technicians on how to handle refrigerants of varying sizes safely and responsibly .
The CFC certification is designed to train individuals on the atmospheric and environmental effects of handing refrigerants. The program comes in types I, II and III. Type I is the most basic and covers all products that contain less than 5 pounds of refrigerant, including most freezers, air conditioners, vending machines, dehumidifiers and water coolers. Type II certification covers all high pressure appliances, and type III covers all low pressure appliances. All tests include a fee that varies depending on the state in which the exam is taken. Those who pass the certification program receive a certification card that allows them to handle refrigerants according to their program type. Most programs offer study materials for an additional fee.
Technicians and contractors can take the type I exam at home through a mail-in form, or they can take any type of the exam at a certified testing center. Information on local testing centers can be found on each state's certification website.
