Carrier 38TXA048 Expansion Valve
Your AC can not deliver properly cooled air if the expansion valve was worn out. Almost all AC systems have an expansion valve that allows the refrigerant to expand back into vapor form from a high-pressure liquid form.
Key symptoms of a defective main expansion valve
- The cooled air is not as cool as it really should be being blown into the house
- Your cooling system takes too long to bring down the temperature
