Whirlpool ATR0943BPP0 Expansion Valve
Air conditioning units cannot possibly cool the house if the expansion valve was totally worn out. Your home AC system contains an expansion valve that makes it easier for the refrigerant to expand into its normal low-pressure gaseous form from a high-pressure liquid form.

- The cool flow of air is much warmer than it ought to be blowing through the ductwork
