These runs of 3/4 flex were originally intended for phone/data lines. The installer found a novel way to ease his pull.

You might also note the failure to close the holes in the drywall around the flex- and this is a firewall. OOPS!

I always knew there was a reason they put them spirals on that stuff.


There are 10 types of people. Those who know binary, and those who don't.

What appears to be the edge of an air handler on the left side may just mean this is an air plenum.
If so, Art. 300.22 has a bunch of requirements that aren't met.

Good thought, Energy. In fact, the unit is a heat pump, with a separate intake duct- so the space is not a plenum.

You mean that we're not looking at an air filter on the side of the unit?

Correct... though I can't say what that really is! The unit is completely contained...a duct for air in and a duct for air out....the heat exchanger is inside, and transfers heat to water, which is piped to the rooftop cooling tower.
I repeat....there is no deliberate air circulation in this ceiling space.
