What is a Whole House Fan?

A whole house fan is a ventilation system that brings cool, fresh air from outside the home indoors. A fan installed in the attic draws air from open windows into the home. A whole house fan has the ability to exchange all the air inside of your home every 3-4 minutes. This drastically improves the indoor air quality and overall feel of the home.

Benefits of Using a Whole House Fan

Whole house fans have many benefits for you, your family, and the environment. These are just a few of the ways a whole house fan can improve life at home: 


  • Improved Indoor Air Quality - A whole house fan removes odors, heat, steam, VOC gases, pet dander, and other indoor air pollutants. Click here to learn more about the importance of healthy indoor air.
  • Decreased Energy Expenses Properly using a whole house fan can decrease energy costs as you rely less on an air conditioning system. 
  • Affordable Installation  Whole house fan installation is affordable and cost effective. 
  • Energy Efficiency Whole house fans are much more environmentally friendly than central or room air conditioning units.
  • Soundless TechnologyThe whole house fans we install are designed to run quietly in the background. You don’t have to worry about a noisy fan keeping you up at night. 

It’s pretty clear that the benefits of having a whole house fan can greatly improve the health and wellbeing of you and your family in more ways than one.

How Do Whole House Fans Work?

Maybe it sounds too good to be true - how does something so simple produce so many benefits and save you money? Let’s take a look at how a whole house fan ventilation system works so you can understand the benefits better.

Thermal Mass Cooling

Thermal mass is a term used to describe building materials that are heavy and dense. These materials work to keep your home a comfortable temperature year-round when utilized strategically during the building process.A whole house fan cools the thermal mass of a home which helps it remain cooler throughout the day. Ideally, a whole house fan will run when it is cooler outside than it is inside - mornings and evenings.The fan draws cooler, fresh air from outside in through open windows while the warmer indoor air is sent out through attic vents. This quickly cools the home and any thermal mass within the home which helps to keep the temperatures lower.

Working Together: Air Conditioning and Whole House Fans

Air conditioning is great when paired with a whole house fan! But air conditioning alone is simply not efficient. Think of using an air conditioner and whole house fan together as a complementary system. 

A great example is getting into a car that’s been sitting in the sun on a summer day. Instead of blasting the air conditioner right away, you open the windows to let the hot air escape. After you’ve let fresh air in, you can turn on the air conditioner and your car cools down much quicker.

Air Conditioning and Whole House

This is the same concept taking place when using a whole house fan and air conditioner together. The whole house fan assists the air conditioner by using outdoor to enter and naturally cool things down. The air conditioner works less - which will help to extend the life and functionality of your air conditioner as well
