Carrier 48GX024060300 Expansion Valve
Your home AC system contains an expansion valve that allows the refrigerant to expand back to its low-pressure gas state from its highly pressured liquid form. The air conditioner for your house would produce no cooled air if it were to lack a properly working expansion valve.
Signs your main expansion valve is on its last leg
- AC takes way too long in a bid to cool your home
- The cooled air is much warmer than it ought to be coming into the house
