What is a plenum and where would I find one?
In building construction Plenum is a separate space provided for air circulation for heating, ventilation, and air-conditioning. It is commonly found in the space between the structural ceiling and a drop-down ceiling or under a raised floor.
Where is the supply plenum?
A supply plenum is an enclosed compartment that’s located just after your heat exchanger if you follow the flow of air through your furnace (see below). When your air handler blows air over your system’s heat exchanger, that warm air is directed into the supply plenum.
