Carrier 50JS030300 Expansion Valve
Your AC unit could not emit cold air if the valve was worn out. A normal AC expansion valve makes it easier for the refrigerant to expand back to its low-pressure vaporous form from its highly pressured liquid form.
Cues of a bad expansion valve
- Your cooling system takes its sweet time trying to cool the indoors
- The air conditioned flow is well below the temp it really should be coming into the home
