Bends and sags in the framing of the ductwork can raise air pollution and reduce airspeed, thereby reducing the quantity of airflow in the system and delaying its heating and cooling abilities. This is one of the most common mistakes in installing the flex duct.
Do not run a flexible duct through small spaces. Wherever you operate the ductwork, the distances should be at least as big as the width of the duct.
When it's being installed, it ought to be mounted or supported each 3-5 feet, never going farther than 6 feet between supports. Do not let for sag either. According to producer guidelines, the maximum amount of sag enabled in a flat line is 1/2" per foot of flex duct.
