Frequently Asked Questions (FAQs)

1. What is the difference between a vent and a register?

WHAT IS THE DIFFERENCE BETWEEN AN AIR VENT COVER AND A REGISTER? An air register has the capability of adjusting the air flow by opening and closing a damper or flaps, usually found at the bottom of the air register. An air vent cover, simply covers the duct without the added feature of adjusting air flow.

2. Are vents also called registers?

“Vent” is a generic term used to cover all supply and return air sources connected to a central air-conditioning system. All registers, grilles, and returns are vents. ... In some spaces, you may have the option of installing a register or decorative grille interchangeably.

3. Are vent registers necessary?

The function of a vent cover is to redirect the air flow from the ventilation system to where it is needed most. Thus, rooms that don't see much traffic should have the vent covers closed while rooms that really need heating or cooling should have the vents left open.
