How Whole House Fans Work: Colorado Home Cooling

Updated: Aug 4, 2021

Many homeowners use whole house fans to reduce air conditioning costs by as much as 90%, but whole house fans are an excellent air conditioning alternative altogether! These quiet, cool whole house fans not only cool your home efficiently, but improve indoor air quality by removing odors, viruses, pathogens and other air pollutants every 3-4 minutes.

Whole house fans work best when the temperature is cooler outside than it is inside — usually in the morning and evening hours — to circulate cool, fresh air throughout your home. As the fan runs, more and more heat is pulled from the mass inside your home, including furniture, walls, flooring, etc. By removing heat from the mass inside, your home is truly cooled down from top to bottom. This process is called "thermal mass cooling."

As the temperature outside begins to rise, turn off your fan, close windows and blinds to maintain cool, comfortable temperatures inside throughout the rest of the day. The thermal mass cooling benefits of a whole house fan keeps your A/C unit from needing to work as hard or as often, reducing a/c-related energy costs and making your home much more efficient.

Using your whole house fan couldn't be easier! When the outside air temperature is cooler than inside your home or attic, do the following:

1. Open a few windows 4-6 inches

2. Turn on your whole house fan using the switch, portable remote, or timer

3. Feel a nice, cool breeze as air passes through your home

4. Experience a complete air exchange in your home in just 3-4 minutes
