How Big Should Ducts Be for AC Units So if you have a two-ton system, you need ductwork that will carry 800 CFM. One six-inch round duct is good for about 120 CFM, a six-inch duct carries about 150 CFM, and eight-inch carries about 200 CFM of cool air.Also, you want to make sure that the return ducts are the same size as the supply ducts.In adjusting your system, try not to damper down the system any more than needed because reduced airflow could cause the indoor coil to freeze.lso, you want to make sure that the return ducts are the same size as the supply ducts.
