FAQ:

Q: Should AC vents be placed in the ceiling or floor?

A: The vent needs to direct airflow to the center of the room and not directly toward a wall, the floor or the ceiling. Similarly, where should AC vents be placed? Supply register vents should be in every room as well.

Q: How do the ceiling vents work?

A: Ceiling vents typically connect to the joists above the drywall ceiling to add stability to the vent as it covers the duct. When your joists are too far from where you need to place your ceiling vent, you can attach the vent directly to the outside of the drywall using drywall anchors.

Q: Do ceiling fans help air conditioning?

A: In a moderately hot weather, ceiling fans can even allow you to avoid air conditioner all together. Many a times it is comfortable enough to have a bath before sleep and then sleep with just a fan put on. Thus ceiling fans can help significantly in cutting air conditioner load.

Q: What is a ceiling vent?

A: Ceiling vents allow air to pass through the attic and out through vents in the roof. When the cooler kicks on, the ceiling vent is automatically opened by the barometric damper responding to the air pressure change. When the cooler turns off, damper closes automatically.
