What is a Smart Vent?

Flair Smart Vents seamlessly replace your existing floor, ceiling, or wall vents. Controlled within Flair's Platform, they open and close to intelligently regulate airflow, effectively eliminating hot and cold spots in your home.

How Do They Work?

Our Smart Vents integrate directly with the Flair Bridge and Puck or collaboratively with your existing smart or traditional thermostats to redistribute and zone airflow even in homes with no current zoning solution. Flair’s secret sauce is our hvacOS™ - a powerful and sophisticated software platform that makes home climate control easy.

Flair Solves the Most Common Airflow Issues

  • Rooms that Over Heat or Cool

    Too Much Airflow

    Fix rooms with excess airflow near the air handler by installing Flair Smart Vents to balance temperature and maintain accurate setpoints. This is an easy, quick and cost effective way to prevent rooms from overheating and/or overcooling. 

  • Rooms that Under Heat or Cool

    Too Little Airflow

    Fix under-conditoned rooms at the end of the duct run by adding Flair Smart Vents elsewhere to redirect airflow and hit the right setpoints. Use Flair’s scheduling features to prioritize rooms at certain times of the day/night. 

  • Whole Home Air Balancing

    Room-by-Room Set Point Management

    Solve whole-home temperature swings throughout the day or season by adding Flair Smart Vents for enhanced zoning and consistent comfort. This is great if you want different set points across several rooms.

  • Handling Vertical Stratification

    Solve for Rising Heat

    Solve overheating upstairs by using Flair Smart Vents to limit heat rise in winter and push more AC upstairs in summer. Most homeowners know this frustration — constantly running around adjusting vents just to stay comfortable.
