Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

If your home already has wires for a ceiling fan (and optional light kit), then it’s quite safe to wire and install it yourself. Always be very careful to shut off the power before you begin, and confirm that the power is safely off with a non-contact voltage tester before touching anything. It’s also highly recommended to use eye protection, rubberized gloves, and tools with rubber handles to keep yourself safe from electric shock.

The number of blades for your fan poses both advantages and disadvantages. Typically, the more blades on a fan, the better the air distribution and cooling effect, but this also means that your fan will have more wear on its motor. For small rooms, three-blade fans should work fine. For larger areas like living rooms, four or five-blade fans might be the better option. 

Generally, a ceiling fan should be mounted at least seven feet from the floor in the center of your room with a wall clearance of around 18 inches. If your ceiling is more than eight feet high, it’s recommended by experts that the ceiling fan be mounted around eight to nine feet from the ground. This helps ensure a better quality of circulated airflow.
