Ceiling fans use much less energy to run than air conditioners, so it would seem love a simple conclusion that ceiling fans save energy, however in most parts of the country, fans do not give enough cooling to upgrade air conditioners, then you may have heard that fans do not cool rooms, they cool people; Fans work for the same reason why wind feels cold; it’s called the windchill effect, however moving air makes you guess cooler because it assists your body’s natural cooling process through evaporation; The more air is moving, the more moisture can evaporate from your skin, making you guess cooler… A ceiling fan does not entirely lower the temperature in a room.
This is why you should not leave a fan on in an unoccupied room because it has no effect in addition to would be wasting energy, and since a ceiling fans task is to cool people, it accomplishes that just fine.
It’s just not a upgradement for air conditioner, especially in hotter temperatures, but you can use them together to create better cooling conditions in addition to possibly save energy. Since fans circulate the air, it makes the temperature more even across the room, in addition to also adds the windchill effect. The reason that people suppose that their ceiling fans save energy, if because fans used to help AC’s work better. The reason is that new air conditioners are so much more efficient, they do not suffer the same problems as early models. Unless your AC equipment was installed before 2000, you do not need to proper temperature variance issues with a fan. Modern ACs are designed to have typical air circulation for the space they are in.
