Begin fastening the ducting in position from the farthest vent line and work your way backward. This procedure guarantees that no air leaks from the vent once it has been installed, resulting in a more energy-efficient system. The technique for mounting a vent to the floor is the same. Duct tape should be used to seal any gaps that remain. Continue in this manner until all of the vents have been installed.
