all. I live in an old Edwardian home where the attic above is a finished loft space so I can't run any ducts upward. I have a second floor bathroom below that needs to be vented correctly. Right now it's only venting directly between the joists. What's really unfortunate is that the current exhaust in the ceiling is literally less than two feet away from an outside wall. But the joists run the wrong way. I don't know a lot but I know not to cut a four inch hole into a joist.
Since the joists run the wrong way there is a bedroom next to the bathroom. I think it'll be around thirteen feet, including the bathroom area to run a duct from that point above the ceiling along the adjacent bedroom to get to an outside wall. My question is, will this be too long to run a duct or will I encounter problems of some sort?
Here is the model that I'd like to get. It has good reviews and appears to be the quietest:
Unless anyone has any ideas for a wall mounted exhaust that is of similar quality and as quiet I feel like doing a ceiling mounted exhaust is my best option.
Hope to receive some suggestions.
