Carrier 48XPN060115300 Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the coolant to expand into its regular gaseous form from a high-pressure liquid form. The AC in an HVAC system would not yield any cooled air if the expansion valve was totally worn out.
Indications of a bad refrigerant expansion valve
- The cool flow of air is definitely not as cold as than the usual air exiting the air handler
- The air conditioner takes its sweet time trying to cool your home
