Carrier 58MSA06012112 Expansion Valve
Pretty much every air conditioning system has an expansion valve that facilitates in helping the refrigerant to expand into its normal low-pressure gas state from a high-pressure liquid form. Air conditioning systems would not yield any cooled air if it were to lack a properly working expansion valve.
Major indications of a bad expansion valve
- The cool flow of air is not as cold as it used to be coming from the air handler
- AC unit takes way too long in attempting to bring down the temp in the house
