Friedrich C24YF Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand into its normal low-pressure vapor form from a high-pressure liquid form. An AC system can not run if the expansion valve was somehow damaged.
Key clues of a poorly performing AC expansion valve
- The air conditioned air is well below the temp than the usual air blowing through the ductwork
- AC unit takes a really long time to keep the house cool
