Many of us dread opening that electric bill to see the damage of running constant air conditioning just to keep our home at a comfortable temperature. Many states and locations do not even utilize air conditioning and therefore need alternative options for cooling their homes in those warm days or nights.

What is a Whole House Fan?

best whole house fan installation

I know what you’re thinking, is this just a huge fan that will be noisy and not really circulate through the whole home? On the contrary, these fans are typically installed through your roof and attic and they exchange cool, outside air for the stale air in your home.

A whole house fan is designed to be energy efficient and offer an alternative method to circulate cooler, fresher air throughout your home. Whole house fans are most ideal in mornings and evenings when the air is cooler. Open your windows and let the whole house fan circulate fresh cool air to cool down your home.

Whole house fans can fully circulate the air in your home approximately 15-20 times per hour. If the system is run consistently at nighttime, it will effectively be able to move all of the mass amounts of hot air outside of your home. The next day, your home will be able to remain cool throughout the day because all of the hot air was completely removed from your home.

Whole house fans are considered alternatives to air conditioners as well as evaporative air coolers, though of course the mechanism by which they cool your house is very different.
