We have two issues with our bathroom exhaust fan - one is that it is noisy and very slow to start working once switched on (sometimes several minutes before the fan starts moving). I presume that will be taken care of with a new fan.
The second issue is the heart of my question: What is the proper ducting for a BR fan?
Our current one is ducted from the BR ceiling, into the attic and up through the roof (white flex duct). In cold weather, we get enough condensation from humid shower air that water drips from the ceiling fixture. Not great, or safe! So we don't use it during cold weather.
How does one avoid this?
My brother in law in Ontario Canada says that there in new houses they run insulated duct horizontally with a soffit exit - final air movement is down. Is that the right approach here in NC? Anyone know what the codes are? Would an insulated duct into attic and roof exhaust be enough to prevent serious condensation?
Other ideas?
Thanks,
Henry
