Over this weekend, I have made a breakthrough scientific discovery that will likely change the world - hot air rises compared to cooler air! :)
My Central AC system has its intake at the ground level, and the ceilings are 8' - it's an older but remodeled house.
I have the space to reroute intake from the floor to the ceiling. My idea: why have the AC unit pulling in the coolest air when it could be working on the warmest air instead? And, additionally, that would be the logical flow direction, so this must be more efficient. With its location it would be easy to construct, too.
My question is, just how much more efficient is this? And do you have any tips on the routing? I will be able to keep a wide radius on the new ducting and it will have at least 20x20 cross-section (equal to the intake). Thanks!
