Circulating fans include ceiling fans, table fans, floor fans, and fans mounted to poles or walls. These fans create a wind chill effect that will make you more comfortable in your home, even if it’s also cooled by natural ventilation or air conditioning. Ceiling fans are considered the most effective of these types of fans, since they effectively circulate the air in a room to create a draft throughout the room.
If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort. In temperate climates, or during moderately hot weather, ceiling fans may allow you to avoid using your air conditioner altogether. Install a fan in each room that needs to be cooled during hot weather.
Ceiling fans are only appropriate in rooms with ceilings at least eight feet high. Fans work best when the blades are 7–9 feet above the floor and 10–12 inches below the ceiling. Fans should be installed so their blades are no closer than 8 inches from the ceiling and 18 inches from the walls.
Larger ceiling fans can move more air than smaller fans. A 36- or 44-inch diameter fan will cool rooms up to 225 square feet, while fans that are 52 inches or more should be used in larger rooms. Multiple fans work best in rooms longer than 18 feet. Small- and medium-sized fans will provide efficient cooling in a 4- to 6-foot diameter area, while larger fans are effective up to 10 feet.
A larger blade will also provide comparable cooling at a lower velocity than a smaller blade. This may be important in areas where loose papers or other objects will be disturbed by a strong breeze. The fan should also be fitted to the aesthetics of the room—a large fan may appear overpowering in a small room.
A more expensive fan that operates quietly and smoothly will probably offer more trouble-free service than cheaper units. Check the noise ratings, and, if possible, listen to your fan in operation before you buy it.
When buying window fans, look for the ENERGY STAR® label. Fans that earn the label move air 20% more efficiently, on average, than standard models.
Upgrading your attic insulation and adding a radiant barrier may be the best ways to efficiency-ize your home, but there are some other things you can do. Installing and correctly using a programmable thermostat is incredibly easy and often overlooked. But if this is a bit overwhelming for you, Mills would be happy to help you choose, install and learn to use a programmable thermostat. This video from US Dept of Energy is a great introduction.
In 2010, Americans will spend $101.6 billion on controlling the temperature of their homes. The average person spends 90% of their time indoors, more than half of which is at home. The more time we spend inside, the more money we spend on heating and cooling our home. If your home is not as efficient as it could possibly be, you are throwing your money away!
When we refer to your home’s efficiency, we’re talking about how well it uses it’s heating and air conditioning system. A poorly insulated home or one with ducts, windows and doors that leak air wouldn’t able to stay cool even with the most powerful AC system. Right now, you may be spending thousands of dollars every year that you don’t need to spend. With a more efficient home, a single upfront investment takes the place of repeated monthly investments that will never end.
Your home is where you spend the majority of your time and it only makes sense to make your home as efficient as possible. Take control of your utility bills and start telling your money where you want it to go, instead of being forced to pay your house to work harder than it has to.

Did you know that the typical U.S. family spends about $1,900 a year on home utility bills? Unfortunately, a large portion of that energy is wasted. And each year, electricity generated by fossil fuels for a single home puts more carbon dioxide into the air than two average cars.
Right in your own home, you have the power to reduce energy demand, and when you reduce demand, you cut the amount of resources, like coal and gas, needed to make energy—that means you create less greenhouse gas emissions, which keeps air cleaner for all of us…and saves on your utility bills! Plus, reducing energy use increases our energy security.
