So my home office is in our basement while my wife’s is in a finished attic space. We have a mini split system, but it has to be all heat or all cooling, and many days it’s cold in my office, but hot in my wife’s office.

Thanks to a defunct chimney, I have a pretty decent path from the attic to the basement that could easily accommodate some kind of ducting.

I’d like to make a system that can push air from my office to hers or vice versa as needed. I think this would really help the house in general as cold air tends to pool in the basement.

I’ve seen plenty of ducting booster fans, but I’d like something with a speed (or at least direction) control accessible from the outside.

Does something like this exist? It would need to force air through maybe 30-40’ of ducting.

    When you say flexible ducting, are you talking aluminized plastic or the corrugated aluminum? That would be a fair amount of weight for flexi in either case, you would want to have access along the route to secure it, especially if it is insulated. The aluminized plastic would need more support than aluminum.

    Without site inspection, I couldn’t say how necessary insulating the duct would be. Using insulated duct would be a good “better safe than sorry” move but will make installation without full access a bit of a bother.
