So running into a new issue-I took a look up into the ceiling and realized that both bathrooms have exhaust fans that are not connected to any ducts going outside! Has anyone have any experience with installing duct from fan to outside through the wall? Is this DIY friendly?
I assume I just need to connect the duct to the fan, then use a hole saw to drill hole through exterior wall. Then connect duct to the hole and cap it on the outside?
