Carrier 50XP030300 Expansion Valve
Pretty much every air conditioning system has an expansion valve that permits the refrigerant to expand into its regular gaseous form from a liquid. Any home AC unit could not emit cold air without a properly functioning valve.
Signs that your Carrier expansion valve is dying
- Cold air is not as cool as it ought to be exiting the vents
- Your cooling system takes way too long in its attempt keep the temperature down
