Average tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Arlington home. There’s good news still—a straightforward bathroom ventilation fan can keep you from warped wood, mold growth, cracked drywall and other trouble associated with a humid bathroom.
Even if you have ventilation fans in your bathrooms, do you know if they’re the right size? Are they as quiet and energy efficient as they could be? Service Max Heating & Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they operate more quietly and efficiently than ever before. You’ll find a large range of selections, from classic fans that will get the job done to fans with fitted heat lamps, motion sensors and heat-exchanger ventilation that helps prevent warmed air from escaping through your ventilation. While there are a lot of bells and whistles to choose from, the most imperative feature of your fan is whether or not it’s big enough to do its job.
Graded by the cubic feet per minute (CFM) of air they push, a bathroom ventilation fan should be able to exchange the air in a bathroom at least eight times an hour. With a typical 8-foot ceiling, your ventilation fan should have a CFM rating about the number of square feet in your bathroom. So, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be satisfactory.
If you have a larger ceiling, the equation gets a little more complicated. You’ll want to multiply the width of the room by its height and length, divide it by 60 and multiply by 8. Or, to keep it easy, you can heed HGTV’s advice for bathrooms larger than 100 square feet – establish your CFM requirements by toting 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
