Payne PA13NR04200GAAAA Expansion Valve
Pretty much every air conditioning system has an expansion valve that permits the refrigerant to expand back to its low-pressure gas form from a high pressure liquid state. Your home air conditioner would not generate and cold air if it was deprived of a functioning expansion valve.
What symptoms are present when the refrigerant expansion valve is dying?
- Your AC unit takes too long to actually bring down the temperature
- AC air production is not as cool as it used to be comes through the ducts
