Payne PY2PNB048090AA Expansion Valve
Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand back to its low-pressure vapor form from its highly pressured liquid form. An air conditioning system can not deliver properly cooled air if the expansion valve was broken.
Major indications the AC expansion valve is going to die
- AC air production is not as cool as you are accustomed to coming from the air handler
- Your AC takes way too long to properly keep the house cool
