Here are the seven telltale signs of a system low on refrigerant: Medium-to-high discharge temperatures; Proper maintenance will improve the systems ability to reduce humidity in the conditioned air. This phenomenon happens from some of the liquid refrigerant experiencing a slight pressure drop and expanding into vapor as it travels through the filter drier. Because the filter drier is located in the liquid line, a restricted filter drier can now be referred to as a liquid line restriction. The condenser gives the current a place to go when the points are in the open position. In some cases, it may be necessary to install a dehumidifier to help the air conditioning system reduce the humidity in the conditioned air. Signs of a Failing Car A/C Condenser.
