In addition to their incredible cooling benefits (a reduction of interior temperatures of up to 30ºF and the attic by a staggering 50ºF), these high volume cooling fans operate on a fraction of the electricity required by traditional air conditioning; a technology that is costing you dollars per hour! Understanding how whole house fans work provides a fresh perspective on how it doesn’t always take complicated and expensive technology to provide multi-faceted benefits. Sometimes all it takes is an understanding of basic physical principles and the ingenuity to capitalize upon these! <br />-381006181725How Whole House Fans Work<br />Whole house fans essentially cool the home in three ways:<br />These high volume ventilation fans set up a powerful circulation that forces all that old hot and stale air out of air vents that are installed in the attic of your home. Now, we all know how intolerably hot the attic can get during the summer. By removing that veritable inferno that radiates heat back into the home’s living space, whole house fans are essentially removing the root of the problem.<br />By opening up windows and doors during the cooler hours of the day, such as nighttime, early morning and evening, these high volume ventilation fans bring all that fresh, cool and clean air from outside the home, inside. In fact, so powerful are whole house fans that they are capable of exchanging the home’s entire air content 15 to 20 times per hour! The combined effect of hot air exhausting from the attic and cool air intake through the window and doors can reduce indoor temperatures by up to 20ºF.<br />-5629275113601514643101155065The third way that whole house fans maintain a wonderfully cool home is through the promotion of a breeze that gently blows from room to room. Depending on how many windows and doors you leave open during the cooler hours of the day, this breeze can reduce skin temperature by as much as 10ºF. This equates to a net cooling effect of 30ºF, which can render expensive air conditioning completely redundant!<br />,[object Object],Through these three different air flows (air expulsion, air intake and circulation from room-to-room), whole house fans are capable of significantly reducing indoor temperatures, and all at pennies per hour. In many cases, these powerful ventilation fans negate the need for traditional air conditioning entirely, enabling home-owners to save as much as 90% on their annual cooling bills… an amount that can equate to as much as $1,880! This is not even to mention the amount of money that is saved on healthcare. Whole house fans continually introduce fresh and healthy air into the home, which reduces the incidence of allergies, prevents the formation of molds and mildew and flushes out the air pollutants that can compromise the health of you and your family. Whole house fans are a great investment that makes use of simplistic physical principles to bring you environmentally friendly, fast and effective cooling.<br />](https://image.slidesharecdn.com/thedynamicsbehindthesuccessofwholehousefans-110808051440-phpapp02/85/The-Dynamics-Behind-the-Success-of-Whole-House-Fans-1-320.jpg)
