What is there to know about whole house fans?

Whole House Fan Operation

Here are some whole house fan basics:

  • Whole house fans work efficiently in temperatures of 85 degrees F or lower and when indoor temperatures are higher than outdoor temperatures.
  • Run your fan at night and in the morning to take advantage of cooler outdoor air.
  • If temperatures reach 86 degrees F or more, turn on the A/C during the day and use the whole house fan at night and in the early mornings.
  • You will need to keep some windows and/or doors open to allow ventilation.
  • If there are rooms you don't want to cool, close them off to promote airflow to the rest of the house.
  • Use ceiling fans or pedestal fans with a whole house exhaust fan to keep the house cooler during the day.
