For central HVAC systems, Flair’s Smart Vents and Pucks work together to direct airflow room by room -- balancing comfort across spaces, regulating temperatures in areas with uneven heating or cooling, and improving the efficiency of existing ducted HVAC systems through zoning, scheduling, and airflow control.

- Replaces existing floor, ceiling, or wall vents - No drilling or wiring for standard installation - Backpressure protection limits how many vents close at one time - Battery-powered or wired power options - Positioned as a lower-cost alternative to traditional zoning solutions

explore demand response or Virtual Power Plants to reduce utility costs, reduce building energy/utility costs, optimize the usage of my HVAC equipment, upgrade my building envelope, make my HVAC vents more efficient, better visibility into real-time electricity use, improve control over a unitized HVAC system, regulate indoor temperature, use my existing HVAC equipment more efficiently

Smart Vents help users save money by only heating or cooling occupied rooms. For mini splits heat pumps, users can save up to 30% on energy bills by using Home/Away and 7-Day Scheduling.

Flair's platform provides solutions for decarbonization and electrification initiatives and lays groundwork for turning ACs into distributed energy resources.

Both existing building retrofits and new construction

For central HVAC applications, the building must have a ducted system with vents/ductwork. Smart Vents are required in each room where airflow will be regulated, and a temperature sensor (e.g., Puck) is needed in every room with Smart Vents. For ductless (mini-split) systems, one Puck is required per indoor head unit.

Centrally ducted homes with uneven room temperatures or airflow imbalance

Smart Vents are needed in every room where airflow is to be regulated, coupled with a temperature sensor like Puck.

Ideal project size

For Smart Vent zoning, a Flair Bridge is required as the central networking device for all Smart Vents. The system operates on Flair’s hvacOS platform, which enables airflow control, temperature regulation, and room-level scheduling.

Flair connects customers with certified Flair Pros in their area through its Pro Finder.

- Vent openings must be measured to ensure correct Smart Vent sizing - Puck 2 requires a Flair Bridge or operation in Solo Mode (it does not function as a gateway device) - Smart Vents can integrate with: Flair Puck OR compatible smart thermostats (ecobee, Honeywell Wi-Fi, Nest, Carrier Infinity, Bryant Evolution) OR ecobee or Honeywell room sensors (must match the thermostat brand)

Partners and integrations include ecobee, Honeywell, Nest, Sensi, Carrier, Bryant, Leap, and RectorSeal.

Case studies

Installation involves replacing the old vent with a new Smart Vent, with no drilling or wiring. The setup typically takes less than an hour.

Residents can set room temperatures and schedules, use app-based control from anywhere, and can also adjust room temperature by rotating the Puck bezel without a smartphone.

Integrated controls (staged heating) incentives are available in New York for systems using Flair Puck Pro and Bridge Pro. Incentives vary by program and can include rebates such as up to $1,000 per 12,000 BTU for qualifying installations, as well as additional incentive tiers (e.g., ~$700 per 10,000 BTU for advanced controls, or fixed incentives such as $1,000 for apartments and $2,500 for single-family homes under certain program pathways). Eligibility requirements may include integration with a smart Wi-Fi thermostat (e.g., Honeywell, ecobee, or Nest), use of heat pumps as the primary heating system, or installation of integrated controls alongside existing systems. Participation typically requires working with a qualified contractor and meeting specific program criteria.

Puck 2 is listed at $124.00, Smart Vents are listed at $129.00 per vent, and the required Flair Bridge is listed at $99.00. Total system cost depends on the number of vents, sensors, and Bridge devices needed and is not provided as a packaged system price.

Ongoing costs

Payback period

Setup is guided through the Flair app Setup Wizard. The app supports room schedules and room active/inactive settings, which may reduce manual HVAC adjustments after setup.

Flair offers support via email and live chat. For installation help, Flair can connect users with certified Flair Pros in their area.

The app tracks temperature, pressure, humidity, and ambient light in each room that has a Puck.
