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.

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.

Identifying the source of noises is your first step to soundproofing a room without overspending. Generally, sound comes from inside or outside of the house. Inside noises include creaking floors, living noises like TVs in the living room, cooking sounds, or kids being kids. External noises generally include incremental weather, disturbing neighbors, and street traffic. Inside noises require you to soundproof floors, ceilings, and doors, whereas outside noises may require you to soundproof your attic, windows, and walls facing the streets.

Not every bathroom needs an exhaust fan. If you have a window in the bathroom, you can get many of the same benefits by opening the window. Moisture in window-less bathrooms can damage your wallpaper, paint, drywall, and wood. It can also result in mold growth, resulting in lung issues, skin irritation, and other health issues. You may need an exhaust fan if your bathroom regularly seems stuffy, traps in smells for a long time, or is prone to mold or mildew growth.

Most installations take 3-6 hours, but complex electrical wiring or additional attic ventilation work may extend the timeframe.
