Whirlpool ATR1243BPP0 Expansion Valve
Pretty much every air conditioning system has an expansion valve that lets the coolant to expand back to its low-pressure gaseous form from a high pressure liquid state. Air conditioning systems would probably be the worst AC in the world if the valve was not present
What are the indications that my AC expansion valve is in need of replacing?

- The cool flow of air is much warmer than it really should be exiting the air handler
