I’m just a young man trying to do what he loves and make some money doing it I’m just one person at the moment but hoping to get a few more people involved. I went to school for 3 years for carpentry I have been working in the field for 6 years I really enjoy it and I take lots of pride in my work.

Exhaust Fan Installation questions, answered by experts

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.

Leaving an exhaust fan on constantly isn’t ideal. While it helps remove moisture and odors, continuous use will lead to wear and tear, higher energy costs, and even fire risks if the motor overheats. Bathroom fans should run for 20 to 30 minutes after a shower, while kitchen exhaust fans should be used only when cooking or clearing air.

You’ll find the backdraft damper near the top of the range hood (where it connects to the ductwork). However, some range hoods also have a second damper, which is located close to the roof or exterior wall where the ductwork ends. If you don’t see a damper in either of these places, you might not have one.

Rigid ducts are easier to clean and can withstand any moisture the bathroom may create, but they are more costly and can’t be easily moved. Flex ducts are a great solution if you don’t have much space and want flexibility in where you place your duct, but they’re more difficult to clean, need a lot of support, and aren’t as sturdy as rigid ducts.
