Payne PH3ZNA030000AA Expansion Valve
The AC in a split system can not deliver properly cooled air if the expansion valve was worn out. Your home AC system contains an expansion valve that allows the refrigerant to expand back into gas form from a high-pressure liquid form.
Main clues the AC expansion valve will need replacing
- The cooled air is not cold enough as you are accustomed to in order to feel comfortable
- AC takes forever to actually keep the house cool
