Section 608 of the Federal Clean Air Act requires that all persons who maintain, service, repair, or dispose of appliances that contain regulated refrigerants be certified in proper refrigerant handling techniques. Persons who work on stationary equipment or use refrigerant designed for these systems can become certified by passing a proctored Section 608 examination. Candidates for this exam can be certified in four categories – Type I, Type II, Type III, and Universal. Each section has 25 questions and is graded independently. A passing score in a proctored setting is 70%, or 18 out of 25 correct.
For students of the 2-day Air Conditioning and Refrigeration seminar, we give the option of taking the Universal EPA 608 exam on the second day and one retake of any failed sections after results are received for no additional cost (a $138 value). The Air Conditioning & Refrigeration seminar does not specifically prepare you to take the exam, so we highly recommend that students planning to take the exam spend concentrated time outside of class reviewing the study guide. A hard copy of the EPA 608 Technician Certification Study Guide will be mailed to you the Monday after you register for the seminar. For more information and to download a PDF of the study guide, click HERE .
Testing for EPA certification is optional, and we cannot guarantee individual success. It is recommended that students who want to take the test attend both days and plan time to study the night before, using the study guide linked above or one provided in the seminar.
