Vent Covers for HVAC Systems


Vent covers allow you to control airflow in your home to optimize efficiency in heating and cooling. Use these covers to redirect or reduce airflow and minimize air leaks that can reduce the efficiency of your HVAC system.


Magnetic vent covers attach securely to your vent to prevent excessive airflow and energy overconsumption. You can also find screw-on and adhesive vent covers that serve the same purpose, helping to give you full airflow control. These air vent covers have a tray that you can slide to access the air vent as needed. They're compatible with a variety of surfaces and flooring, including hardwood, vinyl and laminate.


Smart vent covers balance heating and cooling in your room for even air distribution. Use these smart covers to reduce airflow in often-unused spaces and control temperatures with a corresponding mobile app. For more home energy tips, check out our how-to guide – Create an Energy-Efficient Home.
