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.

Some say that the upper returns should be closed when the heat is running (to circulate out the cold air), and the lower returns should be closed when the A/C is running (to circulate out the warm air). Others say that they should always be open (so the HVAC unit doesn't have trouble pulling in air).
What direction should the return air grilles face?
