Carrier 38BYC030 Expansion Valve
Almost all AC systems have an expansion valve that facilitates in helping the refrigerant to expand back into vapor form from a high pressure liquid state. Your AC unit cannot possibly cool the house if the valve was not working.
Main clues your refrigerant expansion valve will soon need to be replaced
- The cold airflow is warmer than the usual air blowing from the vents
- The outdoor AC unit takes too long in its bid to cool the home
