OK, so I had a problem with my tool-bar, that's why the need for a repost. anyway, you can see the location of my main return to the bottom right of the photo. So the theory is if you run the blower, it'll take the heat and circulate it through the house. But isn't most of the heat up high, and not on the floor? Would it actually "suck" the hot air down the return? And if so, How often would the blower need to run to redistribute it to other areas of the house. And would the minimal amount of heated air going down to the cold cellar ducts, cool it anyway, before it makes its run through the system? Just curious if anyone has tried this out successfully? I guess it wouldn't hurt to give it a try when the season hits.
