ABSTRACT:
A method of cleaning an air conditioning system utilizes a maintenance unit. The maintenance unit has a recovery compressor, recovery condenser, a recovery evaporator, and recovery expansion valve. Operating the recovery compressor draws refrigerant from the air conditioning system, filters it, and passes it into a storage container. To clean, a control valve leading from the storage container is opened to flow refrigerant from the storage container into both the high pressure and low pressure sides of the air conditioning system compressor. The recovery compressor continues to operate to apply a pressure to the air conditioning system up to a maximum level. Once this is reached, or a selected time interval elapses, the pressure in the air conditioning system is again reduced and brought to a vacuum, causing refrigerant to flow back out of the air conditioning system, bringing with it foreign matter.
