The best part is the energy savings.
To work efficiently, ceiling fans need to be correctly sized for each area of operation.
How to Measure Ceiling Fan Size

Ceiling fan size is measured as if the rotating fan were drawing an imaginary circle.
This is because few ceiling fans have an even number of blades.
Five- and three-blade ceiling fans form the majority.
Ceiling Fan Energy Savings
How much energy can you save by installing and using a ceiling fan?
That more than pays for itself in terms of HVAC energy savings.
Why Ceiling Fan Size Is Important
Ceiling fans are meant to move a certain volume of air.
Increasing the speed of the fan will do little to increase that volume.
Instead, the fan needs larger fan blades.
At the same time, you do not want the ceiling fan to be too large for the space.
Not only does this waste money but the fan can visually dominate the room.
A 44-inch ceiling fan, for example, will move 3,600 to 3,700 cubic feet of air per minute.
Conversely, a small fan in a large room cannot adequately move enough air to be effective.
These fans are appropriate for spaces of 50 square feet or less.
If possible, use a fan between 42 and 48 inches for the best air-moving capacity.
You may need to open up the ceiling to create additional support for larger fans.
