I am still training for my first inspections.
Recently I was touring a new res. construction in my neighborhood
and noticed a 1/4" orange flexible pneumatic tube running around the perimeter of the main floor rooms, inside the wall cavity, about 12" off the floor.
I traced it out to the condensers, maybe heat pumps, outside, but it wasn’t connected to anything yet.
Can anyone tell me what this was? Is it an HVAC component?
Thanks,
Tim
