OK, playing catch up here.
We met with our HVAC guru, (www.PeakHVAC.com) and we'd been trying to figure out the best way to heat and cool the house. We at first thought we'd head a vent and return on each side of the dining room fireplace, but it turns out we'd need a lot more space for a second vent to carry air to the 3rd floor and it would make the dining room all.... wonky. Also, it would mean branching out in the basement and taking half of the vent-age (my word, not Chuck Phaeler's from Peak HVAC, heh heh) to the north side of the house and half to the rear, and we'd be talking uber-soffets like an encompassing, but warm, octopus.
So we determined we could fit the HVAC main ductwork up from the basement, up through the northeast corner of the kitchen (practically unused space), into the northeast corner of the bath/laundry room, and then into the 3rd floor. This way, the ductwork stays in a central location, and only branches out from the 'trunk' at the level it is needed.
There was one problem though with the return that was planned for the kitchen wetwall.
Well, we planned the location of the kitchen wetwall ever so carefully, making sure that the wetwalls on the second and third floor would all like up and even distribute some weight. I'm, not kidding, we spent HOURS trying to determine the exact location for premium placement and ease of use. But did we go into the basement and check out the ceiling to make sure that the joists that ran throughout the house also matched up in the basement? Nooooo, that would have been way too smart. Way.
So we built the kitchen wetwall not only right on top of a joist, but to make it all the more painful, it was a double joist.
The plumbing that we so carefully planned for had to come up through the wetwall on the west, then back across over the kitchen to the east, then back up through the floor to meet the bathroom on the second floor. OK, plumbing disaster averted... but the HVAC? Not so easy.
A few days after we made the plumbing work-around, Chuck (the HVAC boss) made the call that we'd have to either move the wall, or we'd have to have an angled return in the dining room that stuck out about 3" on the floor and sloped back to the wall to get around the joist screw up.
We moved the wall.
Now I'm halfway tempted to tell the plumbers that we can now run the PVC up the wetwall the way it was supposed to go in the first place-- just to see the looks on their faces.
Today's agenda: Replace last two rotted floor joists on the first floor with 2x12" PTL (Pressure treated lumber), and start pulling up the rest of the old tongue and groove 1" flooring (wearing a mask this time so as not to kill myself by inhaling the mold on the underside THIS time.) Then overlay with two full sheets of 1/2" OSB ( laid out so as to overlap and not have the edges on the second layer line up with the edge of the sheets underneath, aka staggered layout) and finish sistering 2x6's to the rotted joists on the 2nd floor for floor supports, fix the holes with OSB, then laying single sheets of OSB for the final subfloor prep.
Unless I have to move another wall.
