cooling with fans

Fans can be excellent cooling devices. In some climates they can be associated to cross ventilation (or to natural ventilation when breezes fail to blow).

Reducing Air Conditioning Use

The air movement provided by a properly sized ceiling fan in a room is equivalent to a 4º-5ºF decreasing in indoor temperatures. That makes ceiling fans a wise option.
