A whole house fan is an inexpensive way to cool the home. It works like a large exhaust fan, that ventilates and cools the home by pulling in the air from the open windows and exhausting the air through the roof/attic.

Whole House Fan is a simple and an inexpensive way to cool and ventilate your home

A Whole house fan is installed in the ceiling/attic so that it can exhaust out the air. Here are some of the important considerations when installing and operating a whole house fan:

• Ensure that windows are open when the whole house fan is operating, to prevent uneven pressure differentials in the home.
  
  
• Avoid back-drafting of combustion appliances via the whole house fan, by careful location of the fan relative to these appliances.
  
  
• During winters, the whole house fan’s opening to the outside should be properly sealed.
