About the Service Valve
Most central air condensing units will have a service valve on both the high side and low side ports. The service valve is used to check the refrigerant charge and to isolate the refrigerant from the evaporator coil when servicing the system. If the valve is not shutting off all the way or is leaking externally, it will need to be replaced.
