TX Valve size

Central City Air uses adjustable expansion valves properly sized and installed correctly this allows us to fine tune the regulation of refrigerant flow so that the right amount of refrigerant goes to the coil.  This occurs under all conditions and keeps the coil as cold as possible, resulting in maximum humidity removal and maximum cooling performance. We do not use fixed expansion valves that cannot be adjusted. The Valve type you would need would be a "B" valve.
