Carrier 38YCG036 Expansion Valve
Your main AC unit would be impossible to cool the home if the expansion valve was either damaged or just not working properly. Your HVAC system expansion valve allows the refrigerant to expand into its normal low-pressure gas form from a high-pressure liquid form.
Signals the AC expansion valve will need replacing
- Your AC unit takes too long to comfortably cool the home
- The cool flow of air is warmer than you are accustomed to exiting the air handler
