Journeymen professionals in the heating, ventilating and air conditioning (HVAC) industry and auto mechanics are required by the U.S. Environmental Protection Agency to be certified to work with CFCs -- chlorofluorocarbons. These professionals must pass a test and obtain a valid "Universal Chlorofluorocarbon Certificate" or CFC card. Although you cannot obtain an EPA Universal Chlorofluorocarbon Certificate online, some of the steps are available over the Internet.
Go to the Environmental Protection Agency's official website and locate a CFC training and certification course near you (see Resources).
Order your test-preparation materials from the institute of your choosing via its online course application form. The technical school of your choosing listed by the EPA will send you course materials along with testing locations and schedules.
Study the course materials. You will be tested over various facets of working with CFCs, such as low-, medium- and high-pressure systems. In addition, you will learn to identify leaks as well as leak repair along with proper disposal methods for CFCs.
Download a copy of the "Application for CFC Examination & Certification" from the HVAC training center which supplied your study materials. If it isn't available online, request that a copy of the application be mailed to you.
Take the CFC Certification test. These tests are typically multiple-choice and available at various dates and times. Upon completion of the test, it will be graded and you will receive your CFC card through the mail.
