What is the correct initial action when servicing a vehicle's air conditioning system that uses refrigerant?

• A. Discharge and recover refrigerant
• B. Disconnect the battery
• C. Open the radiator cap
• D. Replace the compressor seals

Answer: (A)

The main idea is that before doing any service on an air conditioning system that uses refrigerant, you must remove the refrigerant from the system with certified recovery equipment. This is the only safe and compliant way to begin work because refrigerant is a regulated substance that can harm the environment and people if released. Recovery ensures the refrigerant is captured and contained instead of vented to the atmosphere, which aligns with environmental regulations and safety practices. Once the refrigerant is recovered, you can proceed with the intended service—evacuation, diagnosis, component replacement, and recharging as required. The other actions listed don’t address the refrigerant in the system: disconnecting the battery, opening the radiator cap, or replacing compressor seals are not the initial step and don’t involve safely handling the refrigerant.
