Question

Quizplus · Accepted Answer

Flushing is the best cleaning method for an air conditioning system that is extremely contaminated. This is because it involves using a detergent solution and high-pressure air or nitrogen to clean out the entire system. Purging, evacuating, and ejecting may be appropriate for certain parts of the system, but they do not provide the comprehensive cleaning needed for an extremely contaminated system.
