Hello,
Im remodeling our kids second floor 5x8 bathroom. We need to replace the fan. I went up in the attic and the current fan has a 3" duct running to the soffit, it just lays there. No vent cap . The plywood under the roof has just light traces of dust/lint. No mold,black spots etc. The duct length is 4ft .
I will need to replace ducting to 4" for new fan. Is it ok to run the new ducting the same route to soffit and add a vent cap with damper ?
Thanks!
