If a bathroom exhaust fan does not have a duct on the side of it but I do have venting present in attic to the outside is the bathroom fan vented

My current bathroom fan is ductless but a friend looked in my attic and said it is vented outside? Can a bathroom fan be venting outside if there is not a duct connected to the bathroom fan light?

Best Answer

It sounds like you're venting into the attic. Just because the attic is vented to the outside is irrelevant. So you're pumping water vapor into your attic, where it's being absorbed by your insulation. That's going to be nasty.

I recommend that you put some ducting in to vent the bathroom directly to the outside.
