EPA 608 Certification — Universal (Core + Type I, II & III)
Pass the EPA Section 608 Technician Certification — the federal credential every HVAC/R technician needs to buy, handle, and service refrigerants under the Clean Air Act. This gold-standard course covers all four sections of the exam — Core plus Type I (small appliances), Type II (high-pressure), and Type III (low-pressure) — so you can earn Universal certification. Plain-language lessons with comparison tables, real exam traps, and the exact numbers examiners test (recovery vacuum levels, recovery percentages, leak-rate thresholds, cylinder rules), a knowledge check per lesson, a randomized 20-question mastery check per section, a full-length 100-question mock exam at real-section weighting, and a spaced-repetition flashcard deck of high-yield facts. Fully updated for current rules including the AIM Act HFC phasedown and A2L refrigerants (R-32, R-454B, R-1234yf). This is independent exam-prep study material and is not the official EPA-approved proctored certification exam.
