International Comfort Products PHAD42N1K4 Expansion Valve
Almost all AC systems have an expansion valve that allows the coolant to expand into its normal low-pressure vaporous form from a high-pressure liquid form. The AC in your house would produce no cooled air if the expansion valve was worn out.
General indicators that your the AC expansion valve is in need of replacing
- Your cooling system takes too long to actually cool your home
- The air conditioned flow is much warmer than you are accustomed to coming into the home
