Okay so my house is set up pretty weird. Our living room which houses are wood stove has a vaulted ceiling. The rest of the house has low ceilings but for some reason whoever built our house decided to create a hallway that juts out with a shelf above it. So I find that all of our hot air gets trapped up in the peak of the ceiling with nowhere to go. The only nice thing is that the main air return is actually located up by the peak where all the hot air is. I’ve attached a few pictures to help give an idea. The return ductwork is a pretty straight shot back and each bedroom has a cold air return located on the upper part of the walls. Here’s my question. I think, if I can attach an exhaust fan to where the main cold air return vent cover is and force the hot air into the bedroom and essentially back feed it into the rest of the house I can help get the back rooms warmer. Is this idea genius or stupid? I should also add that although the cold air returns are located toward the ceilings my main duct work runs through the crawl space so I don’t think it would be worth just trying to kick the main furnace fan on. If this idea won’t work, does anyone have other suggestions? I’ve tried fans at the end of the hallway pointed either direction and didn’t see much change.
