Expert guides, refrigerant recovery procedures, and proven strategies to help you pass the EPA Section 608 Universal Technician Certification exam with confidence.
The ultimate roadmap to EPA 608 Universal Certification success. Learn proven study strategies, master all certification types (Core, Type I, II, III), understand refrigerant recovery procedures, and discover insider tips from certified HVAC professionals. Includes 8-week study plan and recovery vacuum level charts.
Master the transition to mildly flammable A2L refrigerants (R-32, R-454B) under the AIM Act. Learn safety protocols, handling procedures, installation requirements, leak detection systems, and how the R-410A phasedown affects your EPA 608 certification and daily work.
In-depth breakdown of all EPA 608 certification levels including Core requirements, Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure chillers), and Universal certification. Includes exam formats, passing scores (72% proctored, 84% open-book), and career path recommendations.
Master proper refrigerant recovery techniques for all appliance types. Learn required evacuation levels (pre/post Nov 15, 1993), recovery equipment certification, cylinder handling (80% fill rule), vapor vs. liquid recovery methods, and AHRI Standard 700-2016 reclamation requirements. Critical for exam success.
Understand leak rate thresholds and repair obligations for systems with 50+ lbs refrigerant. Master calculations for comfort cooling (15%), commercial refrigeration (20%), and industrial process refrigeration (35%). Learn 30-day repair timelines, verification testing, recordkeeping requirements, and 125% reporting rules.
Comprehensive guide to refrigerant classifications, environmental impacts, and regulatory timelines. Learn the differences between CFCs (R-12), HCFCs (R-22), HFCs (R-410A, R-134a), and new A2L refrigerants. Includes ozone depletion potential (ODP), global warming potential (GWP), phaseout dates, and pressure classifications.
Master recovery equipment certification requirements for equipment manufactured before and after November 15, 1993. Learn about third-party EPA certification, passive vs. active recovery devices, equipment maintenance (oil and filter changes), and proper cylinder labeling (DOT requirements, color codes, refrigerant identification).
Essential safety protocols for refrigerant handling including personal protective equipment (gloves, goggles, SCBA), proper cylinder storage and transportation, nitrogen use for leak detection (never oxygen or compressed air), pressure relief valves, and ASHRAE Standard 15 oxygen deprivation sensor requirements.
