The disclosure relates to apparatuses and methods for indicating status of multi-phase vacuum-assisted recovery of refrigerant from a vehicle. One apparatus for multi-phase vacuum-assisted recovery of refrigerant from a vehicle includes a compressor that removes refrigerant from the vehicle during a first phase and a second phase of a recovery process. The apparatus also includes a vacuum pump to assist the compressor in the removal of refrigerant from the vehicle during a second stage of the recovery process. Further, the vacuum pump is fluidly connected in series with the compressor during the second phase of the recovery process. The apparatus additionally includes one or more status lights and at least one processor to determine a status of the recovery process. At least one of the status lights is illuminated to represent a status of the recovery process, and at least one is visible from 360 degrees around the apparatus.
