Good eye. I've already addressed that, but I think it needs more
attention. I'm going to have a guy who works with these Ultra-Aire
units take a look at it. I was told the Ultra-Aire 150H has a lot of
power, so it will still manage to suck the fresh air it needs through
the flex duct, but I'm not sure how accurate that somewhat
non-scientific statement is. I'll look into it some more.

I'm not sure what kind of wood the 2x4s and 2x6s are. The joists are
all 14" engineered joists--you know, the kind with the laminated top
and bottom rails with the OSB in between. The floor truss systems
(including the engineered joists) and the roof truss systems were all
"engineered" by the truss company that sold us the pre-built roof
trusses and pre-sized floor joists and LVL beams. I've been told the
engineered joists are slightly more expensive, but as strong or
stronger than their traditional lumber alternatives, and much more
reliable as far as straightness and consistency load-bearing-wise.
Thanks for the feedback!
