About this item

• HOT ATTICS, COLD BASEMENTS — FIX THE ROOMS YOUR AC CAN’T REACH: If certain rooms in your home never cool down or heat up properly, the problem isn’t your central AC — it’s airflow. This booster fan installs in any standard 4″×10″ vent to push conditioned air exactly where you need it, so every room gets the comfort your HVAC system was designed to deliver.
• WORKS WITH YOUR EXISTING HVAC SYSTEM IN MINUTES: This smart vent fan connects directly to your 4″×10″ floor, wall, or ceiling register. The built-in thermostat senses real-time room temperature and automatically adjusts fan speed (10 levels) to match your climate needs. Set it once, and it runs on its own — no manual adjustment needed.
