The Best Air Duct Registers

Air duct vent covers are easy to install and give you maximum control over the airflow coming through your HVAC system. Some covers have louvers that will direct the air in 2 or 3 directions at once. Some models pop up for even further control over airflow direction.

You can also close off the air duct cover in an underused room that you don’t want to heat or cool — thereby saving money on your energy bills.

Aesthetics

Air duct covers come in many colors and styles. From white to brown or tan and even antique brass finishes. In addition, many models can be painted to match with a variety of color schemes and looks in your home.

For homeowners with a historic or Victorian-style home, consider air duct vents with a fancy scrollwork design to go along with the home’s vintage-style decor.

Affordability

Basic air duct vent covers are quite affordable. For a simple yet heavy-duty style, buy a pack of 6 for less than $40.

Durability

Air duct covers are heavy-duty and made to withstand foot traffic. Many are made from steel. Some have plastic components to avoid rust problems, such as in the damper boxes. However, they use a sturdy, impact-resistant plastic that can take the heat.

Easy Installation

Installing new air duct covers is a cinch. Simply remove the old cover and drop the new one in. Position the louvers in the desired direction of airflow and it’s all set!

Keep in mind that when choosing a new air duct cover, sizes are based on the air duct opening — not the actual dimensions of the product itself. For accuracy, always measure the air duct opening rather than the old cover.
