Bathroom Fan Installation FAQs, answered by experts

The direction you want your ceiling fan to move in depends on the season you’re in. During summer, you want it to move counterclockwise to produce a cooling downdraft. During winter, you want it to move clockwise to circulate warm air throughout the room.

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.

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.

Yes, you can lubricate a ceiling fan without taking it apart. Ensure the fan is off and clean any dust around the motor area before lubricating. Apply several drops of machine oil to the top of the motor housing where the shaft enters or via the oil ports if available. Regular lubrication helps maintain smooth operation and reduces noise. If your fan lacks an accessible oil port, it may require disassembly or professional maintenance.

Yes, you can oil an electric fan with machine or motor oil but don’t use cooking oil because it can become thick or seize up, damaging the fan. Before oiling your fan, turn it off and remove any dust and debris. Wipe away any excess lubricant after oiling.
