During the evacuation of a mobile AC system, approximately 0.5 to 1 ounce of moisture can be removed, depending on the system's condition and the duration of the evacuation process. The primary goal of evacuation is to eliminate moisture and any non-condensables, as moisture can lead to ice formation and damage to the system. A thorough evacuation typically lasts about 30 minutes to an hour, ensuring that the system is free of contaminants. Proper evacuation is crucial for optimal performance and longevity of the AC system.

Manufacturers typically recommend a system evacuation time of 30 minutes to 1 hour for air conditioning systems. This duration helps ensure that all moisture and contaminants are removed from the system, preventing damage and ensuring optimal performance. However, the specific evacuation time may vary depending on the size of the system and the vacuum pump's capacity. Always refer to the manufacturer's guidelines for the best practices specific to the model being serviced.
Charging hoses should not be used for evacuation because they are typically not designed to handle the vacuum conditions required during the evacuation process. They may contain impurities or moisture that can contaminate the system, leading to inefficiencies or damage. Additionally, their construction may not withstand the pressures involved, potentially resulting in leaks or failures. Using proper evacuation hoses ensures safety and the integrity of the refrigeration system.
A tiny bit of oil may be removed during the evacuation of the system. This is not enough to require the addition of oil as most of the oil will remain in the system.
The line to the refrigerant cylinder is purged after evacuation and before charging to remove any air, moisture, or contaminants that may have entered the line during the evacuation process. This step ensures that only clean refrigerant enters the system, preventing potential damage and inefficiency. Purging also helps maintain the integrity of the refrigerant charge and ensures optimal system performance.
