Carrier 48XZN042090300 Expansion Valve
Almost all AC systems have an expansion valve that allows the refrigerant to expand back into its natural gaseous form from a high-pressure liquid form. Any air conditioner would most likely give you heated air with no functioning valve.
Simple warnings that your expansion valve is about to stop working?
- AC takes way too long to appropriately keep the house cool as it should
- The air is much warmer than you are accustomed to blowing from the vents
