It depends on the humidity inside the house, the CFM per ton of air
flow and the type of metering device (TXV or piston or cap tube) on the
indoor coil. Normally it is 16 degrees to 20 degrees below the return
temperature in the supply plenum just off the coil. The air will pick
up some heat traveling down the duct as well. 55 degrees is good, but
if your return temperature is 80 degrees, 60 degree supply air is more
likely. If it is very humid, the temperature could be higher still.
