Carrier 50GL048300 Expansion Valve
Pretty much every air conditioning system has an expansion valve that facilitates in helping the refrigerant to expand back into its natural vapor form from a high pressure liquid state. A split-system AC unit would be impossible to cool the home if the expansion valve was either damaged or just not working properly.
Major clues that your Carrier expansion valve is going out
- AC takes forever in its effort to keep the home at a comfortably cold temperature
- Air flow is warmer than you are accustomed to blowing through the ductwork
