Evacuation is a crucial process in air conditioning installation and repair where technicians remove moisture and air from an AC system before adding refrigerant. Think of it like preparing a clean, empty container before filling it with something important. This step is essential because any moisture or air left in the system can make the air conditioner work poorly or break down. When you see this term in resumes, it usually means the person knows how to properly prepare AC systems for operation, which is a fundamental skill in the HVAC industry.
