"I was introduced to Sacry through a third party. But I have now found an electrician for life! They showed up with little notice, analyzed the scope of what to be done, and made some recommendations. These recommendations were not so they could charge more, but rather so the job could be completed safely, and look professional. Sacry Electric went out of there way to make sure I was satisfied. I wish more companies had the same values as Sacry, putting the customers wants, needs, AND budget as their only priorities! Thanks again Sacry! I will be calling again soon!"

Exhaust Fan Installation questions, answered by experts

Exhaust fans push air out of spaces, removing moisture, heat, odors, and pollutants. They vent air outside through ducts, preventing mold and improving air quality. Unlike ventilation fans, which circulate fresh air in and out, exhaust fans focus solely on expelling unwanted indoor air.

Not all exhaust fans need venting, but most do. Bathroom fans and range hoods work best when vented outside to remove moisture, odors, and pollutants. Some ductless range hoods use filters instead, but they don’t remove air—just recirculate it. Proper venting ensures better air quality and efficiency.

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.

Mold thrives in wet and humid conditions, and the bathroom can often be an ideal place for it to grow. If you are worried about mold, it's a good idea to hire a local mold inspector to inspect your bathroom. 

How you handle the mold depends on the extent of the issue. If it's on the caulk or other surface, a deep cleaning with mold-killing products such as vinegar or bleach may be sufficient. For a large infestation, you'll most likely need professional mold remediation.

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.
