“Dustech ADP make Plenums are more accurately referred to as “plenum boxes,” which form a crucial part of the ductwork in any forced air system. Generating hot or cold air is only half of your AC, furnace, or heat pump’s job. Once it has heated or cooled the air, it must then move that air through ductwork, circulating it through your home. After the heated or cooled air circulates through your house, it comes back to your HVAC unit, which draws it in to heat or cool it once more. Plenum boxes are usually situated on either side of the fan or heat exchanger and have the important function of bringing in, distributing, and removing air. They are the air the air’s first stop after being heated or cooled and its last stop before going back into your AC, heat pump, or furnace. Almost all systems have two plenum boxes: the supply plenum box and the return plenum box
