Sorry. New construction in the drawing phase. Split on bench in garage, then 8' away over the kitchen will be a plenum, from there about an 18' run for trunks and branches in the floor trusses. So Cal, so a little more heat dominant.
With it presumably being "Open Construction", I'd have the Supplies in the floor, & Hi Wall or Ceiling Returns.
Thank you for taking a good look at this. Far right corner is tub/shower, then toilet, then vanity, then WI closet, so the dotted line by the stairwell is where I was thinking it might be best for the return. No door to closet and no door from bed to vanity area. But that also brings up another question. If you look close there is a small rectangle with a/c in it right across from that dotted area in the wi closet I was thinking of having another chase there for supply for wi, van. and toilet areas, by adding a soffit at ceiling level above the vanity with registers in all 3 areas. But having the return so close to a supply doesn't sound good. The whole area is only about 400 sq ft, so the bedroom area about 260, I am wondering if I could use just one large supply to the corner by the patio and use the other by the stairs as a return instead of in the wi closet. Thanks
That is practical. I suggest a small supply vent in the vanity. Near the return, but put the return above the stairs instead of in the vanity.
Thank you for the map link. That's an excellent resource. The 2nd link I read, but not sure how that would be applicable to myself. My project isn't a diy although my questions would seem like it. It will definitely be let out to an HVAC contractor after we get energy calcs etc. I've never drawn a 2 story before and I am trying to get plumbing, electrical, fire sprinkler lines, and hvac figured out so I'll know what depth/height floor trusses will be required, mostly hinging on trunk size, 2-20x8 rectangle or 2-14" flex's.
