In high-pressure systems, the typical evacuation level is indeed higher than that in low-pressure systems. This is primarily due to the operational requirements and the nature of the refrigerants used in these systems. High-pressure systems need to be evacuated to eliminate moisture and non-condensable gases effectively, which could significantly affect the performance of the system, leading to inefficiencies or system failure.

Evacuating to a lower pressure in high-pressure systems helps ensure that the refrigerant cycles efficiently and prevents damage to the compressor and other components. Thus, achieving a more rigorous evacuation level becomes crucial. In comparison, low-pressure systems may require a different threshold for evacuation due to the characteristics of the refrigerants and their operational pressures, making the evacuation level for high-pressure systems typically higher. This understanding helps technicians apply the right procedures based on the specific system type they are working on.
