System component identification comprises another significant examination topic. Technicians must recognize and understand the function of compressors, condensers, receivers, expansion devices, accumulators, and hoses in mobile air conditioning systems. Questions may ask about proper connection points for recovery equipment, safety relief valve locations, and how to identify system types. Practical knowledge about how these components work together to cool vehicle interiors and maintain system pressure appears throughout the examination.

Refrigerant recovery techniques receive extensive examination coverage because proper recovery prevents environmental harm and protects equipment. Test questions address when recovery becomes necessary, which recovery methods apply to different system conditions, and how to document recovery activities. Candidates learn about passive recovery, active recovery, and system evacuation procedures. The examination also covers situations where technicians must notify the EPA about improper refrigerant releases, as certain conditions trigger mandatory reporting requirements.

Safety protocols and hazard recognition form critical examination components. Technicians must understand the dangers of refrigerant exposure, including frostbite risks from rapid evaporation and asphyxiation hazards in poorly ventilated spaces. Questions address protective equipment requirements, safe handling practices, and proper storage of refrigerants and recovery equipment. The examination includes scenarios requiring technicians to identify unsafe conditions and determine appropriate responses.

Tool and equipment knowledge ensures technicians understand proper use of recovery machines, pressure gauges, manifold sets, and evacuation devices. Questions may describe scenarios where equipment must be calibrated, maintained, or replaced due to contamination.
