Bathrooms are very warm and humid environments so making sure they are properly ventilated is important. Most bathrooms 
have a ventilation fan which is usually fitted to the bathrooms ceiling, this is connected to a duct which runs all the way to the outside of the house. This form of ventilation, however, does not always perform in the way it should. What could be some reasons for this?
One reason could be a build up of dirt and dust that causes the fan to become clogged and stop working effectively. There is a simple solution for this and that is to give it a thorough cleaning.
Another reason for the fan to function incorrectly is that the duct work might not actually reach to the exterior of the home, but instead, be vented into the attic space. You might not see too much of an effect on the bathroom itself with this problem, but it could end up doing a lot of damage to the attic. This is because the damp environment it produces will encourage the decay of materials used in this space and even cause mold.
So, what are some signs that your bathroom fan is not working properly? Look for excessive moisture on bathroom walls and ceilings. The metal fixtures in the bathroom might start to corrode and you could see peeling and bubbling of paint because of the high levels of humidity.
