Carrier 58STA090 Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand into its normal low-pressure vaporous form from a high pressure liquid state. Any air conditioner would not produce cooled air without a working expansion valve.
Major symptoms of an unhealthy AC expansion valve
- The air conditioned flow is well below the temp it used to be as it comes from the air conditioning unit
- The cooling system takes a really long time to appropriately cool the indoors
