Haier CPR10XC9-L Expansion Valve
Your AC unit would be broken if the expansion valve was either damaged or just not working properly. Pretty much every air conditioning system has an expansion valve that allows the coolant to expand into its regular gas state from a high pressure liquid state.
Major indications of a declining main expansion valve
- The air conditioner takes too long in a bid to cool all the rooms in your house
- The air is well below the temp you are accustomed to for the AC to cool the house
