The short answer is, yes, ceiling fans do help to keep rooms cooler. That’s what they’re designed for, after all. You may not be aware that ceiling fans don’t actually cool the air in a room, but they do work to make you feel cooler. The fan creates a breeze that evaporates perspiration on your skin, which cools you down. Fans also create a wind-chill effect on your skin and lower your body temperature by blowing air over it.
But before installing new ceiling fans, there are some things worth considering first like how big or small the room will be where it’s going? What type of material should we use for our blades? How many blades do we want them? Let’s take another step back here – let’s consider what kind of fan would best suit our needs?
Ceiling Fans and Central Air Conditioners Work Best Together
A ceiling fan works well with a central air conditioning system. It helps reduce the amount of energy you have to use to keep your home cool, saving you money on your utility bills. The moving air produced by a ceiling fan makes you feel cooler than you really are, and can make a room feel up to 8 degrees cooler. This is especially helpful at night when temperatures drop but there’s still humidity in the air. Also, if it’s not too hot outside and there’s a breeze blowing through your open windows, using a ceiling fan can help circulate that cool breeze throughout the room without wasting energy on your AC system.
Using a Ceiling Fan to Draw Cool Air up From the Floor in Summer Can Help You Feel 10 Degrees Cooler
For those sweltering hot summer days that have you feeling less like the human being you are and more like a swampy mess, ceiling fans can make all the difference. They even have the potential to help you keep your cool. Although they don’t actually cool down the air in a room, ceiling fans can make you feel cooler by keeping air circulating your body (think wind chill factor!). That’s why running a fan alongside an air conditioner can improve its efficiency and help it perform better. It will also allow you to set your thermostat up about 4 degrees with no reduction in comfort, allowing for energy savings of 10 to 40 percent on your heating bill!
It’s important to note that ceiling fans aren’t just for summer use. If used properly in the winter months, they may be able to save you upwards of 10 percent on heating costs. Since warm air rises and cool air falls, having a ceiling fan push warm air back down into the room can help heat things up without cranking up the heat as much as usual. To circulate warm air downward, just reverse your fan direction so that it rotates clockwise at low speed (most fans have switches or buttons on them to adjust rotation). Just make sure to shut off or reverse your fan when leaving the room so that it isn’t working overtime when no one is there enjoying the “free” warmth!
And remember: just like any appliance and most pieces of furniture in your home, keeping those blades clean is essential for optimal performance. Dust buildup on a fan blade will throw off its balance, making it wobble and run louder than usual – not only annoying but potentially dangerous if neglected long enough! A good habit is to wipe them down at least once every few months with a cloth or feather duster free from dust mites and other allergens.
You can save as much as 15 percent on cooling costs by using ceiling fans instead of your air conditioner, depending on the outside temperature. For example, if you set your thermometer at 78 degrees when you use the fan instead of 72 degrees when the air conditioner is on, the fan can lower your electricity bill by as much as 12 percent to 15 percent. The key is that it depends on how hot it is outside.
If it’s very humid and over 90 degrees outside and you don’t have an air conditioner, a ceiling fan won’t be enough to make a room cool. If you do have an air conditioner and want to use a ceiling fan alongside it, set the thermostat higher than normal — perhaps 7 or 8 degrees higher — but use your fan so that the air will circulate throughout your house more effectively.
A well-maintained ceiling fan can help you shave off a few degrees of heat on hot summer days and make your home more comfortable.
