Bathroom Fan Making Noise? Bathroom vents can become notoriously noisy when it gets windy, making your home sound like a horror movie. If this banging sound doesn't seem to go away, there's a way to fix it. You won't have to wake up in the middle of the night wondering if someone has broken into your house.
If you hear noise from the bathroom fan when it's windy, there's an easy explanation. It's because the wind is picking up the vent flapper and dropping it down repeatedly. You can resolve the issue by adding sound absorption, weight the damper, or replace it with a spring.
The possible causes and solutions depend on whether or not your bathroom fan ventilation system is equipped with a backdraft damper. If there's no backdraft damper, pressure changes and drafts entering the ducts create vibrations and noise. When dampers are present, blocked or broken flaps and operating mechanisms can allow air in as well.
Bathroom vent flapper noise can be quite annoying. Wind causes the flapper to move, creating unwanted sounds. Identifying the source of this noise is crucial.
It helps in finding the best solution. Knowing the patterns and inspecting the vent is key. Noise Patterns Noise often occurs during windy days.
The flapper makes a banging or clattering sound. Sometimes, it sounds like a constant. I have a two-year-old home which has vent fans in the two bathroom ceilings.
We live in a windy area, and the flabber doors on the fans are often banging open and shut. The noise is annoying, but I'm also concerned about the heat loss in the winter. The fans are vented out the roof through a vertical pipe connected to the fans by an insulated flexible ducting above the ceiling.
I've tried. My vent fans run to the side wall, and there is a very lighweight plastic damper in the fan unit, and an aluminum damper under the vent cover on the outside. I get a little flapping noise on windy days, but nothing I would call banging.
The vent fans in our bathrooms make loud clapping noises when it's windy. I can open/close the doors to the bathroom quickly and hear the flap clapping because of the pressure change. A noisy bathroom fan is more than annoying.
