International Comfort Products NDC7125BKA3 Expansion Valve
Pretty much every air conditioning system has an expansion valve that makes it easier for the refrigerant to expand back into gas state from a liquid. An AC system would be impossible to cool the home without a working expansion valve.
Red flags your refrigerant expansion valve will eventually need to be replaced
- The cool flow of air is not as cool as it really should be in order to feel comfortable
- The air conditioner takes too long to appropriately cool all the rooms in your house
