How Whole House Fans Work

How Whole House Fans Work

Open a few windows any time it’s cool and comfortable outside, typically in the evening, night and morning times. 

  • Turn your QuietCool fan on by setting the speed and timer 
  • QuietCool pulls in cool, fresh air from outside through open windows
  • QuietCool blows cool air into the attic, forcing existing hot air out attic vents
  • Your home has now been made cooler, healthier, and more comfortable with less AC use

When your QuietCool Whole House Fan is turned on, the fan 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. This helps cool the home and attic by up to 30 ºF or more.

Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations.

According to the ALA, effective ventilation may also help keep bacteria, viruses and other pollutants out of the indoor air. Research shows that airflow and ventilation can alter how diseases spread indoors. The more stagnant the air is, the more likely diseases are to spread. Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Indoor air can build up high levels of moisture, odors, gases, dust, and other air pollutants. To keep the air safe indoors, fresh outdoor air is needed to dilute these indoor pollutants.

Per the CDC as it relates to COVID-19, to keep your house safe, the CDC specifically recommends opening windows and increasing ventilation.
