A whole house fan is a ventilation cooling system that uses less energy than a traditional air conditioner. This energy-efficient system works by pulling cool, outdoor air into your home and out your attic vents. When whole house fans are turned on, the fans will pull the cooler outdoor air into your home, through your windows, across your living space, into the attic, and out the attic vents, replacing the hot, stale air.

Quiet cool whole house fans help cool the home and attic by up to 30 degrees Fahrenheit or more. The first important step is to ensure that the outdoor air is a temperature you would like in your own home. If it is, simply open 3-4 windows and turn on your whole house fan. This process will flush in the outdoor air and flush out your stale, indoor air. All-day long your attic is heating up like a furnace under the hot sun. The heat in your attic causes a tug-of-temperature war with your air conditioning system as it struggles to keep your home at a constant cool temperature. Keeping away the hot air in your attic is key to keeping temperatures and energy use low.

A whole house fan is essential in every home across the country because of the many benefits it offers. Benefits for a whole house fan installation are, making the house feel 5-10 ºF cooler, save up to 50-90% on A/C cooling costs, expel cooking odor, pet dander, smoke, germs, gases, & other unwanted airborne annoyances. Feel refreshed, cool, and comfortable with clean, outdoor air.

Whole house fan system works when the windows in the home, or in a room you want to cool down quickly, are opened. The air flows from the outside, through the home and then expelled back outside through the attic vents. The circulation of air is like having ceiling fans in every room to help ventilate and draw in the fresh, natural air. Attic fans work great to ventilate the attic, to decrease its temperature, and to help preserve the roof. Whole house fans draw in the outside air to rapidly cool the rest of the interior by at least 10 degrees right away. The system is constantly replacing the air in the house up to 20 times an hour, which will further decrease the temperature by 20 degrees. As the hot air is dispersed through the attic, the temperature in the house can maintain a cooler temperature for longer, decreasing your air conditioning’s run-time.

A whole house fan will work as long as the conditions for it are right. This would mean that the outside temperatures would have to, in fact, be cooler than the temperatures inside your home. For example, if the temperatures during the summer months are not cool enough even during the nighttime, then you are probably better off just using your air conditioning system instead to guarantee you cool temperatures. If summer night temperatures tend to drop where you live, then a whole house fan could be a great option for you and your family.
