He installed a blade fan with a light.I would highly recommend using him as an electrician and have already referred him to a friend in my neighborhood."

Bathroom Fan Installation FAQs, answered by experts

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.

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.

Before committing to this new project, you’re likely weighing the pros and cons of attic fans. The good news is that typical roof vents can only ventilate 150 to 300 square feet per unit, whereas a single attic fan can circulate enough air to vent an entire attic. By moving large volumes of air within and out of the attic space, an attic fan can lower the temperature by 15 to 40 degrees Fahrenheit and reduce moisture to prevent mold and mildew.

In short, no. You can use the square footage range chart in this article to determine the right size ceiling fan for both indoor and outdoor spaces. However, weather elements can damage types of ceiling fans that aren't designed for outdoor use, so your ceiling fan should be weather-resistant if you plan to install it outside.
