Bryant 310 Expansion Valve
Pretty much every air conditioning system has an expansion valve that makes it easier for the refrigerant to expand back into its natural gaseous form from its highly pressured liquid form. The AC in your house could not cool the air if the expansion valve was worn out.
General warnings of an unhealthy main expansion valve
- The cooled air is not cold enough as you are accustomed to coming from the air handler
- Your cooling system takes too long to cool all the rooms in your house
