What is an Air Register?
Answer:
An air register directs heated or cooled air
through a series of ducts into various rooms of a building. Depending on the design of the room, an air register could be installed in the floorboards, along the lower wall, under a window or possibly the ceiling.

An air register generally redirects and diffuses the air flowing from the furnace or air conditioning unit.  To accomplish this, the room end of an air register almost always contains elaborate grill work or directional vents.  The heated or cooled air moves through this grill or vent and ideally flows along the floor and walls to reach most if not all of the area efficiently.  An air register may also have a damper system which would cut off the incoming air supply if the room's temperature became uncomfortable.  Some air register models also direct air in multiple directions for a more even result or to prevent the air from blowing too hard on a specific area or person.

An air register system should be cleaned on a regular basis to avoid a build-up of house dust and other possible allergens.  There are accessories available which can cover an air register temporarily, redirect the flow of air or diffuse the airflow from above to reduce drafts.  Manufacturers of air registers can also offer numerous styles which match the general design elements of the house, from elaborate metal Victorian grills to modern vents with adjustable vanes and a variety of colors.
