How to Install a Floor Duct Boot
HVAC (Heating, ventilating and air conditioning) systems include a furnace and/or air-conditioner and the ductwork that runs from this equipment to the supply air registers that expel heated or cooled air into your home's various rooms. Between each supply air register and the duct is a floor duct boot. These boots are essentially adapters that connect the round duct to the register. One end is round and connects to the ductwork; the other end is flush with the floor and is the size and shape needed to accommodate the register. These are among the first components of an HVAC system to be installed.
-
Measure the dimensions of the square opening on the duct boot. Mark these out between two floor joists on the floor where you want the boot.
-
Cut out the hole in the floor with your reciprocating saw.
-
Insert the square opening of the boot into the opening from below. Have another person bend the tabs of the boot over from above to hold it in place.
-
Nail the tabs of the boot down to the floor.
