Carrier 40MFC012 Expansion Valve
Your home AC system contains an expansion valve that allows the refrigerant to spread back into gaseous form from its highly pressured liquid form. Air conditioning systems can not run if the expansion valve was somehow damaged.
Signals your refrigerant expansion valve will need to be replaced
- Air from the AC is not as cold as it used to be exiting the air handler
- The air conditioner takes too long in its effort to bring down the temperature
