Payne PY2PNB048115AA Expansion Valve
Every air conditioning system contains an expansion valve that makes it easier for the refrigerant to expand back to its low-pressure vaporous form from its highly pressured liquid form. The AC for your home would probably blow heated air if the expansion valve was totally worn out.
Clues of a faulty expansion valve
- The air conditioned air is not cold enough as it used to be coming into the home
- Your AC unit takes forever to appropriately keep the house cool as it should
