Convert portable AC to mini central AC. Any reason why this would not work?


I may do that, the through the wall could go in the bedroom and the existing in my office. I did install a dedicated 20 amp circuit for it so may as well use it. How well do those through the wall units work in winter? Are they well enough insulated and sealed so I wont have a massive heat loss?

But if this won't work, then I might stick to just hauling the unit around. As for the cooling of the compressor, I modded the unit so it uses outside air hence the intake/exhaust pipes. I found this made a huge difference last year.
I bet you could get it to work. You might not have enough cooling capability, but I don't see why it wouldn't work. It just might be a hard thing to explain if the house burned down for another reason..

You NEED returns, and even if you did it is probably way undersized.

Dont bother.

The purpuse of Air Cond. is to REMOVE HEAT FROM AN AREA..... how will your rooms properly cool if there are no return air?

Naturally two bodies of air will want to equalize, if they are able to. So if I depressurize the basement and pressurize the upstairs then naturally air will be pushed down through vents, cracks etc. Though, I have no furnace return in the basement, so to fix that I may actually add one right where the upstairs return is, so that would create a direct path. But TBH, I don't think the returns would be an issue. I installed an inline fan for my bathroom and when I close the bathroom door, I can feel air coming out of the furnace vent. In fact it makes the shower curtain move. Those inline blowers really do have quite a lot of balls.

The only issue is hot air rises, and I'll be trying to push it down, so that may possible pose a challenge. It was an idea, but I'll probably drop it.
