A duct problem or bathroom fan problem?
The bathrooms forum doesn't seem to have many people posting about ducts, so I'm posting here.
Our bathroom fan has mostly conked out. It works, but it kicks in several minutes after turning it on. But -- it will always turn on. Half-way through my shower. Odd.
We have a crawl space rather than an attic, really, and the duct runs perhaps 25 feet across to a vent that is on the side of the house. The fan itself has gotten quite dusty over the last few years, bits of the blown in insulation. And even when it worked (and was cleaner) it did a weak job ventilating the bathroom -- I bet it is a Nutone or something, probably 8 or 9 years old, that is circular and decorative but not particularly powerful. (And it is a bit loud by today's standards.)
So... does the fan's not starting for a while sound like a fan problem or a duct problem? Our wonderful independent electrician will clean and oil a fan, or replace a fan, but not do ductwork. I'm hoping this is a fan problem but not a duct problem.
