International Comfort Products C9MPD075F12C1 Expansion Valve
Pretty much every air conditioning system has an expansion valve that makes it easier for the refrigerant to expand back into gaseous form from a high-pressure liquid form. Your main AC unit would not generate and cold air if the expansion valve was somehow damaged.
How do you know if your AC expansion valve has to be replaced?
- Your AC takes a really long time to actually bring down the temp in the house
- The cooled air is not as cold as it used to be exiting the air handler
