A ceiling fan is a type of electrical appliance mounted on the ceiling that uses rotating blades to circulate air and cool down a room. It is often used to create a more comfortable environment by providing a gentle breeze, especially in warmer weather. Ceiling fans can also help with air circulation in colder months by pushing warm air down. They come in various designs and sizes, with some offering additional features such as lights or adjustable speeds. Ceiling fans are an energy-efficient alternative to air conditioning.
