Personal finance weblog The Simple Dollar recently found that, on average, having a ceiling fan running in a room makes it feel around four degrees cooler. Australian government studies show that setting your air conditioning temperature 1.8 degrees higher can reduce its running time by 10%. Putting both of these factoids together posits that you can save around 23% of your air conditioning costs by using a ceiling fan and setting your thermostat at 78 instead of 74.
Furthermore, according to The Simple Dollar’s calculations, dropping the running time of your central air from 9 hours to 7 hours per day using this technique will save you around $34 a month. The cost of running a 48″ ceiling fan on high 18 hours a day will cost around $5.82 a month which means that unless you have more than five ceiling fans in your house running simultaneously you’ll be saving money on your energy bills. They estimate that if you put a ceiling fan in each of the rooms you spend a lot of time using that you can save around $100 a year on energy expenses. Well worth considering if you’re trying to lower your energy expenses, and also remember that you can run the fan in reverse in the Winter to heat your home more effectively. Photo by Steve Johnson
