International Comfort Products PYPA Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the coolant to expand into its normal low-pressure gas form from a high pressure liquid state. An AC system would not generate and cold air if the valve was missing.
Major clues of a poorly working refrigerant expansion valve
- Your AC takes too long to comfortably keep the house cool as it should
- The air conditioned air is not as cool as it really should be streaming from the vents
