Winterizing Your Whole House Fan

Winterizing your whole house fan is really important in making sure that you're keeping the heat inside your house in the winter time, as well as reducing unwanted noise caused by windy, cold winter days.

Installation is super easy! All you'll need is a step ladder, a winter insert, and the grate-puller that comes with your fan.

To install your insulated whole house fan insert follow these simple steps:

 

  1. Place your step ladder directly underneath your fan grille, and make sure you have stable footing on the ladder. 

  2. Use one hand to support one side of the grate. With the other hand, use your grate puller to gently tug the grate away from the damper box.

  3. Place the winter insert snuggly inside the grille — it should be a perfect fit!

  4. Snap the grille back into place.

That's it! Your whole house fan insulated winter insert is ready to keep the warm air in and the cold air out all winter long.

IMPORTANT: DO NOT RUN YOUR FAN WITH INSERT IN PLACE. Your fan is going to be completely sealed when the insert is in place — running your fan with the insert in place can damage your fan motor.

Keep The Hot Air In And Cold Air Out!
