Carrier 58CTA04510008 Expansion Valve
Your HVAC system expansion valve allows the refrigerant to expand into its normal low-pressure gaseous form from a high-pressure liquid form. Any home AC unit would probably blow heated air if the valve was not working.
What are the signs that the expansion valve has a need to be replaced?
- The cold airflow is not as cold as it should be coming out of the vents
- The outdoor AC unit takes too long to properly keep the home at a comfortably cold temperature
