How Do Whole House Fans Work?

Before the advent of the whole house fan, there were 2 basic options for staying cool at home in the hot weather:
  • Using a ceiling or table fan to blow air on people within the small air flow area so that they felt a little cooler.
  • Using air conditioning to cool the structure.
The problem with the first option is that all it really does is circulate the same old air and it is the movement of the air on the skin that creates a sense of coolness. The room itself or the house does not really become much cooler. Air conditioning does effectively cool the room or house, but it consumes a huge amount of electricity, so the operating cost is high. Also, buying and installing air conditioner is expensive. Another factor to keep in mind is that with air conditioning, the amount of fresh, clean air that enters the home is limited. The need for a cost effective and highly efficient way of cooling the home has been met with the development of the whole house fan.



Cool Air, Fresh Air, Indoors And Out

Whole house fans have revolutionized the way homes are cooled. They stand out for their efficiency and effectiveness. Air conditioners and fans are costly to buy and run or operate in an efficient manner. They also take time for the cooling to become tangible. A properly designed and manufactured whole house fan from a leading company will effectively cool down a home in just a few minutes. Whole house fans do not push air in the direction where the limited circulation is required. Instead, they pull the stale warm air out of the whole house. Because of the outflow of stale air, fresh cool air is able to enter the home though open windows and cool the whole house. Whole house fans are mounted in the attic so they are able to pull air from all the lower floors.

While a whole house fan can be used at any time of day, the best results are obtained if it is used when the outside temperature is lower than the temperature indoors. This new air will be cooler than the air it replaced. Once the interior has been cooled, closing the windows will help to retain the coolness for hours until it is time to run the whole house fan again. For example, running the fan in the morning will cool the house and keep it comfortable through the hot afternoon. This is done at a fraction of the cost of running an air conditioner.

All Whole House Fans Are Not the Same

How effective a fan is and its durability and reliability depends on how it is manufactured. If you are considering installing a whole house fan, look for one made by a highly reputed company that has the following features:
  • Longer lasting strength and energy efficient operation with brushless motor
  • Rust proof operation and durability with powder coated metal fan blade
  • Fan with 5 blades for smoother airflow
  • Insulated ducting ensures quiet cooling
  • Airflow is maximized with a damper box design
  • A cleaner look as there are no visible vents
