A ceiling fan provides 5 basic benefits:summer cooling, winter heating, energy savings, ambient illumination and beauty. You’ll want to place the ceiling fan in rooms that are most often used by family members. Among the most important applications are living and family rooms, kitchens, alcoves, bedrooms, bath areas, porches and verandas. 
- Summer Cooling Ceiling fans create airflow, a breeze that cools people in the room – reducing or eliminating the need for air conditioning.
- Winter Heating Ceiling fans recirculate the warm air at the top of the room, which raises the temperature nearer the floor, where people stand and sit.
- Energy Savings By their cooling and warming effects, ceiling fans reduce the need for air conditioning and heating. This in turn reduces the annual cost of electricity, gas, or oil by as much as 30%, depending on the size of the room and the climate.
- Ambient Illumination Adding lighting elements to the fan provides ambient illumination. One electrical appliance accomplishes both goals, which saves on material and installation costs.
- Beauty A ceiling fan provides an attractive visual focus to a room. It is one of the first features a guest notices when entering a room. The interplay of forms and materials in the housing, blades, and lighting can be very pleasing.
