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.
Should have been more precise. I have a funny situation. My house has had four major remodels performed over the past 80 years. One of them involved extending the roof and totally covering a chimney (there is another chimney elsewhere in the house). Rather than remove the chimney, they built around it including adding a closet on the middle floor. The closet is wider than the chimney, but the whole thing is framed out as a rectangle, so I have like 1x2’ of empty space leading from my attic to the basement ceiling.
So not need for liners.
I’m by no means an HVAC expert, but I was thinking that pulling hot air from the hottest point in the house (attic room ceiling) would provide the best circulation. Thinking more about it, I think I’d be better off having it be one-directional if only so I can install a filter to keep it from filling up with dust. I can convince myself that either direction is the better option. Maybe I’ll install the blower somewhere in the middle where it’s easy to access.
Thanks for the advice!
