Carrier 38BYG030 Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the coolant to expand back into its natural gas form from a high-pressure liquid form. A split-system AC unit can not supply your house with cold air if it was deprived of a functioning expansion valve.
Warnings your refrigerant expansion valve is dead
- AC unit takes way too long in attempting to bring down the temperature
- Cooled air is well below the temp it used to be comes through the ducts
