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.

Whether you can install a ceiling fan yourself depends on if you're replacing an existing fixture or installing one where no wiring exists. If you are replacing an existing fan, an experienced DIYer may be able to do the job, which can save on labor costs. This work typically doesn’t require a permit, but there’s always a safety risk when dealing with electrical components, so hiring a pro is still a good idea, especially if you aren't handy. Keep in mind you may need a special ladder for high or vaulted ceilings. However, if you are installing a new ceiling fan where there is no current fixture, you must hire a licensed electrician. In most areas, it is required by law that a professional runs new wiring and pulls the necessary permits. Attempting to install wiring yourself can be dangerous and a code violation.

If you’re removing a ceiling fan without visible screws, start by locating the fan canopy—a round cover placed above the fan blades and motor. There should be a thin ring that can be turned counterclockwise to remove the canopy and reveal the screws. After unscrewing the fan, you can disconnect the wires and remove the entire fan from the mounting hardware. For safety, make sure the fan switch is turned off before you remove the canopy. It may be easier to remove the fan blades first, too.

If you’re replacing an old fixture with a ceiling fan, you usually won’t need a permit, but if your electrician runs new wiring for the fixture, you likely will need a permit. Building permits are necessary in most municipalities if you’re making changes to your electrical system, so even if you have partial wiring run to the area and need new wiring installed for added functionality, you’ll probably need a permit. Your electrician should be able to let you know if you need one, and they’ll typically file the paperwork for you.
