Air conditioning units could not cool the air if the valve was missing. Every air conditioning system contains an expansion valve that makes it easier for the refrigerant to expand into its regular vapor form from a high-pressure liquid form.
Major clues your main expansion valve needs to be replaced

- Cold air is warmer than you are accustomed to comes through the ducts
