To replace a damaged AC compressor, the first step should be to

• A. Discharge and recover the system refrigerant
• B. Disconnect a battery
• C. Verify engine oil level
• D. Calibrate the thermostat

Answer: (A)

When replacing an AC compressor, the essential first action is to recover the refrigerant from the system. The air conditioning circuit is a sealed, pressurized loop, and releasing or venting refrigerant is dangerous and illegal. Using certified recovery equipment keeps people safe, protects the environment, and satisfies regulations before any component is removed. Once the refrigerant is safely recovered, you can proceed to remove the faulty compressor, then evacuate the system and recharge it as needed. Other steps like disconnecting a battery, checking engine oil, or calibrating a thermostat aren’t part of the initial compressor replacement and don’t address the system’s safety or integrity.
