While it is a myth that air return grilles are required in each and every room in the house, it is definitely necessary to have more than one of these grilles installed at strategic places in the house. Likewise, you can also install these in rooms that have a high footfall or usage in the house.
What is the difference between grilles and registers?
Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. Louvres, or dampers, are often attached to the back of a heat register. A grille has no damper to control air flow, so air is left to flow freely. Grilles do not have the damper normally found on registers.Apr 9, 2014
