Quizplus · Accepted Answer

Technician A is correct. Internal restrictions like blockages or debris in the system can reduce the speed of evacuation. Technician B is incorrect because it is not necessary to remove all of the oil during evacuation. It is important to remove enough oil to ensure that the refrigerant charge is not contaminated, but leaving some oil in the system can actually help to maintain proper lubrication once the system is back in operation.
