Bathroom Fan Installation FAQs, 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.

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.

Ceiling fans are very often worth the investment because they improve comfort in your living space and help reduce utility bills. In the late spring and early fall—and even in the summer in some areas—homeowners with ceiling fans can often get away with open windows and fans, which can cut down on cooling bills and also reduce wear and tear on the HVAC system. Over time, ceiling fans can pay for themselves by saving you money on electric bills and air conditioner repair and maintenance.

Every municipality has its own codes. But generally speaking, all bathrooms must have some ventilation, whether it's a fan or a window. Check your local building codes before doing any bathroom fan installation to make sure you are meeting the code requirements. A reputable electrician or bathroom fan installer will be able to answer this question.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.
