Carrier FX4CNF018000 Expansion Valve
Your AC would produce no cooled air if the expansion valve was broken. An expansion valve allows the coolant to expand back into gas state from a high pressure liquid state.
Indications the expansion valve will die soon
- The cooled air is definitely not as cold as it ought to be so as to feel comfortable in the house
- AC unit takes way too long to actually keep the home at a comfortably cold temperature
