Smart Vents for central heating and cooling
Say goodbye to hot and cold rooms and save up to 30% on your utility bills.
Flair Smart Vents replace the vents you have now and adjust airflow room by room. Rooms that need more air get it, and rooms that are already comfortable get less. Keep your thermostat and your ductwork.
One thermostat can't fix every room.
Most homes with central heating and cooling run on a single thermostat in a hallway. It reads one temperature, so the upstairs, the finished basement and the bedroom over the garage are left on their own. Turn it down for the hot room and the rest of the house gets cold.
- Uneven temperatures. Some rooms stay cold while others are too hot.
- Wasted energy. Every room gets heated or cooled, whether it needs it or not.
- Air sent to empty rooms. You pay to condition space nobody is using.
- Consistent comfort. Each room stays at the temperature you set.
- Lower energy costs. Save up to 30% on your utility bills.
- Room-by-room control. Rooms you don't use are set to away.
Sensors read the room. Smart Vents fix it.
Room sensors on a smart thermostat change which temperature it follows. They can't change where the air goes, so favoring the hot bedroom overcools the rest of the house.
A Flair Smart Vent replaces a floor, wall or ceiling vent and opens and closes on its own. With a Flair Puck or a supported room sensor in the room, each room gets its own set point, and Flair sends the air where it's needed.
Keep the thermostat and sensors you already own. Flair gives them a way to move the air.
How it works
Three parts, one system.
-
01Measure each room.
Your thermostat stays in the hallway. Every room with a Smart Vent gets a Flair Puck or supported room sensor, so Flair knows the temperature in that room. Rooms without Smart Vents only need one if you want Flair to track that room too.
-
02Move the air.
Smart Vents open and close to send more air to the rooms that need it and less to the rooms that don't. A Flair Bridge connects your Smart Vents, Pucks and thermostat to the Flair app.
-
03Run it around your day.
Set a temperature and schedule for each room in the Flair app. The office during the day, the bedrooms at night, and the guest room off until someone visits.
Room sensors must be paired with a thermostat of the same brand.
Fix one room or the whole house.
Start with the rooms that bother you most, or balance every room in your home.
Too much airflow.
Rooms close to the furnace or air handler run too hot in winter or too cold in summer. Smart Vents in those rooms cut the extra air and send it elsewhere.
Too little airflow.
Rooms at the end of a long duct run never warm up or cool down. Smart Vents in other rooms push more air toward them, and schedules can put them first when you use them.
A different temperature in every room.
Bedrooms at 68, the office at 72, the guest room inactive. Smart Vents and room sensors throughout the home keep each room at its own set point.
Heat that rises upstairs.
Upstairs too warm all year? Flair limits the heat going up in winter and pushes more cool air upstairs in summer.
Stop paying to heat and cool empty rooms.
A single-zone system sends air to every room, all day, whether anyone is in it or not. Flair closes vents in rooms that are already comfortable or empty, so more of the air you pay for reaches the rooms you're in.
Flair Smart Vents can save up to 30% on your utility bills. Savings are usually largest in hot climates where the ductwork runs through the attic.
Inactive rooms
Take the guest room or formal dining room out of the schedule, and Flair stops conditioning it.
7-day schedules
Set each room for when you use it. No daily thermostat adjusting.
Home/Away and Smart Away
Flair sets your system back when nobody's home, within safe limits for pipes and pets.
Temperature holds
Change a room's temperature and it returns to your schedule later, so one change doesn't undo your savings.
About $1,000 saved in one summer.
A Flair Pro added five Smart Vents and five Pucks to a home with uneven rooms, working with the existing thermostat and replacing no HVAC equipment. All five rooms held steady at 68, and peak summer bills dropped about 35% compared with the year before.
Results reported by the installing Flair Pro for one home. Your savings depend on your home, climate and how you use it.
What homeowners say.
How Flair compares with the usual fixes.
| The usual fix | What happens | With Flair Smart Vents |
|---|---|---|
| Closing vents by hand | Right for one season, wrong for the next, and it raises the pressure on your system | Adjusts all day, every season, with built-in equipment protection |
| Running the fan all day | Mixes the air without balancing rooms, and uses electricity every hour it runs | Sends air to the rooms that need it |
| Room sensors on a thermostat | Change which room the thermostat follows, so other rooms get too hot or cold | Uses room readings to change where the air goes |
| Booster fans | Pull more air into one room and move the problem somewhere else | Balances airflow across the whole system |
| Traditional zoning | Dampers in the ductwork, a zone panel and new wiring, often thousands of dollars | Replaces your vents, room by room, with no ductwork opened |
| Adding a mini split | A new indoor and outdoor unit for one room, with its own remote | Uses the heating and cooling you already have |
Installs with a screwdriver, not a renovation.
Fits your existing vents
Ten standard sizes from 4x10 to 12x12, for floor, wall and ceiling vents.
Install it yourself
A Phillips screwdriver and the Flair app. Battery powered with low-battery alerts, or wired on 24VAC.
Protects your HVAC system
No more than one in three Smart Vents in a zone close at once. If the internet goes down, every vent opens.
Grow room by room
Fix the worst room now, then add Smart Vents and Pucks when you're ready.
Want even tighter control? Have a pro install it.
Professionally installed Pro systems measure your duct system's static pressure in real time, so more vents can close safely. Pro+ adds fan speed control for finer airflow, down to a single room.
Works with what you already have.

Smart Vents work with a traditional thermostat. Supported smart thermostats add more control.
