When a household refrigerant compressor doesn't run it is recommended that low and high side access valves be installed when recovering refrigerant from the system because of?

installing low and high side access valves allows for a more efficient and complete recovery of refrigerant from both the evaporator and condenser sides of the system.

Additionally, it helps to isolate the system and allows for easier troubleshooting and maintenance of the compressor and other components.
