International Comfort Products TCH448AKA1 Expansion Valve
Almost all AC systems have an expansion valve that permits the refrigerant to expand into its normal low-pressure gaseous form from a high-pressure liquid form. The air conditioner for your house would not yield any cooled air without a working expansion valve.
Subtle cues of an unhealthy main expansion valve
- Air from the AC is well below the temp it used to be coming from the AC
- Your AC takes a really long time to comfortably bring down the temp in the house
