Ceiling fans·15 guides
Cooling your home without air conditioning
A ceiling fan does not cool the air: it moves it, and that movement on the skin is what lowers the temperature you feel. Understanding the difference stops you expecting what it cannot do, and underrating what it can.
These guides deal with heat as it is lived: a heatwave in a flat, the floor under the roof, airless nights, and an honest comparison with air conditioning.
