How Long Can You Run a Ceiling Fan? How Long Can You Run a Ceiling Fan?

Ceiling fans are a good way to circulate air throughout a home in both cool and hot weather. If you own a ceiling fan, you may want to know how long you can keep it on at any given time. Is it a good idea to run the fan constantly even when no one is in the room? Is this a waste of energy? The following article will explain the basics of energy usage.

Air Circulation

Generally, it is acceptable to leave your ceiling fan on for a long time. It's even safe to leave it on when no one is in the room, if the purpose of leaving it on is to circulate air and maintain a consistent room temperature. In very hot weather, for example, it can be beneficial to leave a ceiling fan on as a way to circulate cool air throughout the house. If you leave the ceiling fan on the room will be a good temperature when you come back to use it.

Ceiling fans can also keep rooms warm. In addition, leaving a ceiling fan on may actually save energy because it improves the effectiveness of a home's HVAC system. If your central heating and air conditioning system doesn't have to work as hard, leaving ceiling fans on can be a good way to conserve energy.

Cooling and Heating

Ceiling fans are good for cooling a room and keeping a warm comfortable temperature. They are also good for air circulation. In fact, air circulation is one of the best reasons to have a ceiling fan in your house. No matter what the room temperature, warmer air rises to the ceiling and cool air falls to the floor. In any weather, turning on the ceiling fan is a good way to keep the temperature more even so that the house remains a comfortable temperature throughout.

Ceiling fans don't actually lower the temperature in the summer, in the sense that they don't affect air temperature. They do create a cooling effect, however, because the moving air from the ceiling fan provides a gentle breeze that causes the human body to cool down. Another reason a ceiling fan cools you down is that it can move cool air from lower areas in the room and evenly distribute them to create a cooler temperature overall.

When used together with air conditioning, ceiling fans can be very helpful. In the winter a ceiling fan does the same thing as in the summer, circulating hot air from the top of a room more evenly throughout the house. Less heat is wasted when a ceiling fan is installed, saving on your energy bill. Some ceiling fans even have heaters included in the design.  

Using a Ceiling Fan in the Winter

When using a ceiling fan in the winter, you may want to put it on a lower setting so that it does not create as much of a breeze. In the summer, creating a breeze is a good way to cool down, but in the winter you simply want to circulate warm air to create a more even temperature throughout the house.
