International Comfort Products GDJ050M12C2 Expansion Valve
Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand into its normal low-pressure vaporous form from a high-pressure liquid form. Your AC unit would be broken if the valve was not doing its job.
Major indications of a deteriorating main expansion valve
- The outdoor AC unit takes a long time to actually keep the home at a comfortably cold temperature
- The air conditioned flow is warmer than it really should be so as to feel comfortable in the house
