Fans in the Winter?! Most people think fans help keep you cool, and they do, but there is more to it than that. Many ceiling fans come with a handy switch that reverses the direction that the blades spin. Standard, counter-clockwise rotations create a cooling breeze for warmer weather. Clockwise spinning, on the other hand, causes the warm air that pools near the ceiling (because heat rises, of course!), to circulate back down into your living space. Running your ceiling fan in reverse will help you enjoy the full effect of your home’s heat, and can actually save you up to 10% on heating costs this winter.
