Carrier 50XT-A24 Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back to its low-pressure vaporous form from a high pressure liquid state. Your AC would be impossible to cool the home if the expansion valve was worn out.
Subtle hints your main expansion valve should need replacing
- The air conditioned air is not as cold as than the usual air being blown into the house
- The cooling system takes way too long in its attempt keep the house cool as it should
