When you think of the VIP’s of equipment in your home, your first thoughts probably go to the ones that keep you the most comfortable – furnace, air conditioner, toilet, shower then probably on to kitchen appliances, but one of the most important pieces of equipment in your home is your bathroom exhaust fan.
Did your mouth just drop open? Are you wondering just what exactly I have been doing all day to come up with that little gem of knowledge? Well, no worries, I am of sound mind and able body and that little exhaust fan in your bathroom has a really big job.
When you use your bathroom for showering or other bathroom business, all kinds of stuff get trapped in there. Everything from steam to stinky smells need somewhere to go and if steam has nowhere to go eventually condensation will build up start to wreak havoc in your home.
There are some important things to note about exhaust fans. Not only is it important that you have them, and important that you use them (meaning, actually turn them on), it is also important that they are properly installed and that minor detail is where things can get tricky.
Building codes say that you must have ventilation in the bathrooms, but it doesn’t specify an exhaust fan so technically a small window counts as ventilation except… are you going to open a window if it is really cold outside? Or hot? Or you are afraid someone may crawl through it? Or you are in a hurry and forget? Or your neighbors have learned your secret code of every time you are using your bathroom you open a window? The reasons you are not likely to open a window for ventilation are endless.
So, let’s forget the window and go back to the exhaust fan – you have it because building codes say you need ventilation, but they do not say where the air has to vent. Here is a cliff note – it needs to vent to the outside. If it is venting air to your attic or dead space between walls you have been set up for major issues to come like mold, mildew and possibly wood rot.
If you are building or remolding a home, do NOT let a contractor talk you into improperly venting your bathroom because “building codes say you can vent to the attic” that is a shortcut that will cost you in the long run.
