One of the main reasons an attic tends to be one of the hottest rooms in a house is that heat rises. In addition to central air conditioning, a potential solution to the problem is a Whole House Fan.

What is a Whole House Fan and How Does It Work?

A Whole House Fan is a method for cooling a house using outdoor air. Whole House Fans get installed in the ceiling of a home between the upper level rooms and the attic and work to help cool a house by continually forcing hot air from the lower floors into the attic and exchanging that hot air with cooler outside air via vents in the attic. In order for Whole House Fans to operate properly, all windows in the house should be opened and the central air conditioning must be turned off.

There are several benefits to using a Whole House Fan. The list includes but is not limited to:

  • Using less energy than central air conditioning
  • Allowing for good attic ventilation

On the contrary, there are several issues to using a Whole House Fan. The list includes but is not limited to:

  • Lacking the ability to dehumidify the air inside a house
  • Allowing pollen and other outdoor allergens to easily enter the house
  • Lacking the ability to cool the air inside a house any lower than the temperature outside
  • Noise
  • Allowing for cold, drafty air to enter the house if it is not properly covered in the winter months
