The push-pull recovery method is used for transferring large volumes of liquid refrigerant. During this process, the recovery unit pulls vapor from the recovery cylinder and produces high pressure discharge gas that pushes liquid out of the HVAC system and back into the recovery cylinder. You should not use the push-pull method if the air conditioning system contains less than 10 pounds of refrigerant, if the system is a heat pump, or if it is a unit with a reversing valve.
