Whole House Fans Save Energy
A whole house fan is a good energy saving device. It is an exhaust system which pulls hot air up into the attic and cooler air in from the windows.
A whole house fan is sometimes confused with an attic fan. An attic fan is limited only to the cooling the attic. While whole house fans are installed in the attic, they keep the whole house cool as well as the attic.
Sometimes temperature in a building can seem much warmer than the temperature outside even when the windows are open. This is because of stillair. Still air can be reduced by ensuring complete air circulation.
Billions of dollars are spent by Americans every year on air condition systems. Air conditioners are really expensive compared to whole house fans. On an average, a whole house fan costs one-tenth the cost of running an air conditioning system.
