Introduction of Grills

Grills are the vents through which air is pulled out of a room for circulation back to the central heating or cooling unit. Grills do not have the damper controls found on floor register.

The following are characters of grills:

1. They have no damper to close off the flow of air.

2. They may be located in floors, ceilings and walls.

3. They provide return air circulation within a room; where unobstructed flow is required for heating/cooling system efficiency.

4. You may have several small grilles located throughout your home or one large central grille installed near the furnace.
