1. A climate control system comprising:
a refrigerant loop for circulating refrigerant within the climate control system;
a connection associated with the refrigerant loop, the connection configured to couple to a charging valve to supply refrigerant into the refrigerant loop; and
a controller configured to:
cause the charging valve to open and close in a plurality of cycles when the charging valve is coupled to the connection;
determine a detected saturated temperature of the refrigerant within the refrigerant loop after each cycle of the plurality of cycles; and
adjust an amount of time that the charging valve is open during each cycle of the plurality of cycles as a function of the detected saturated temperature from a previous cycle of the plurality of cycles.
