International Comfort Products T9MPV050F12A1 Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the coolant to expand back to its low-pressure gas state from a high-pressure liquid form. Your AC unit would be impossible to cool the home without a working expansion valve.
Important signs your main expansion valve will eventually need to be replaced
- Cooled air is not cold enough as it used to be coming from the AC
- The air conditioner takes a really long time in attempting to bring down the temperature
