Abstract
A method for using refrigerant to check for a leak in a refrigerant system is provided that establishing fluid communication between a refrigerant recovery unit and a refrigerant system. The refrigerant recovery unit passes a refrigerant through the refrigerant recovery unit, compresses the refrigerant utilizing the refrigerant recovery unit, and transfers the compressed refrigerant from the refrigerant recovery unit directly into the refrigerant system. Additional refrigerant is added into the refrigerant system until a desired system pressure is reached, and then the refrigerant system is checked for leaks.
