air handler in the attic

[mtldesigns]

Happy Thanksgiving to you all Chiefer's...

 

 

I have another small house, 1200 sq. on slab, pretty simple house actually (needed this break honestly).  I am putting the air handler in the attic.  I've done this a hundred times I think, however on my truss plans I always note for the truss manufacturer to make available space for these units with a W x L.  I'd like to step up my game and actually show this space in my design, but how do I make this happen?  Do I need to create a floor for my attic, even though nothing is on it and designate a "room"?  Or do you model those trusses separately?

However you decide to do it, just DO IT.

Huh,

What kind of answer is that ??

I would just place a solid above the truss cords just as it would be built with a sheet of 3/4" ply if it is sitting on the truss cords. It is also possible that they would be hanging the unit from above? Either way, you need the plywood runway and work platform at the unit so back to the fake sheet of plywood. I would not make the attic space into a new floor and room because that creates a bunch of new work in reassigning normal walls to become attic walls and I just don't need that kind of stress in my life. I have been too busy training for a turkey trot for the last 47 minutes.

Hang a platform. Four connection points, 2 adjacent trusses' top chords. 

 

No worries about overloading bottom chords. Less vibration and noise below. Better drainage slope on primary and secondary pan drains. Easier access.

I go over this in the following video at about  the 26 min mark

Thank you, I will try this out.  I tried over and over again to make a room definition like you had tried, (I used invisible walls so not to get wall framing) and still couldn't get that to work.  I think if WE could have gotten that area to be defined, the truss framing would have worked.  I did stop short of creating a second floor though.

 

The floor plan is in the customers hands now, so when it comes back and I do the truss designs for the constructions docs, I'll keep you posted on my results.
