Exhaust Fan Venting

There are two ways to do exhaust fan venting – the right way and the wrong way.    We all love hot showers but the normal warm air and steam build up in a bathroom can be harmful.  You need to get rid of it correctly.  

This recent question below from a customer illustrates a common issue with exhaust fan venting.

” … I would like to see if our bathroom exhaust fan can be replaced so it vents to the outside instead of the attic.”

Obviously some people choose the easy way when installing a bathroom fan.   That poor choice can be due to lack of knowledge, lack of skill, or other factors.   However, the results can be damaging to your home over time.

The Right Way

Building codes have required exhaust fan venting to carry air to the outside of the building for many years.  Not just into the attic, but completely outside of the building.   Exhaust ducts should provide an unobstructed path out of the house, either through the roof or through a wall.   Duct work should not be droopy or turn sharply in a way which traps the moisture inside.  It should allow the fan below to push the air out quickly before condensation can start.  Otherwise, water droplets can form and drip back down inside the home where they can pool and allow mold to grow.

The Wrong Way

Some bath vents just come through the ceiling and insulation and stop right there.  When the venting does not go outside, the warm moist air stays in the attic and problems arise.   The moisture can saturate wooden framing or panels, causing them to rot or weaken.  It can build up on the insulation, causing a black mold to form.  Pooled water could also support animal or insect life in your attic.
