Do Fans Use As Much Electricity As Air Conditioners. Fans use up to 100 times less electricity than air conditioners. Additionally most climates the AC cools the air and removes humidity.
Sometimes running both a fan and an air conditioner gives you the benefit of air conditioning at a lower cost. In comparison with powerful AC systems these units are more. The average unit has a 500 watt fan which uses almost as much energy over the course of the year as a refrigerator resulting in a 50month bill.
Doug Keffelers answer is correct.
Allowing a fan to run for hours on end even in areas that are not in use defeats the whole purpose of energy efficiency. Green Building Advisor an online source for home energy efficiency says that the typical whole house fan uses about 200 to 700 watts only 10 to 15 of the power drawn from a central-air-conditioning system which usually use about 2000 to as many as 5000 watts. On cooler days this time of year I often turn my window AC unit to the fan setting to pull in some of that cool air from outside. In comparison with powerful AC systems these units are more.
