I tried to explain in another post a few weeks ago but that didn't work out too good.
This time I even have a mini picture I did in MS Paint.
The main trunks are the black line in the back. They sit about 10 feet from the addition.
Assuming I can run the supply (s) into the wall right above the foundation and of course the new floor. And then can I run the return into the foundation wall in the corner which you see in this illustration? There is going to be a massive girder so can't really run it into the room. And can't go through the side wall because the joist is going to be there.
Also assuming 8 inch lines on both.
Looking for advice and clarification from an HVAC guy. I don't do HVAC, usually hire out which I may still end up doing but want to be able to discuss this with them too.
