There’s lots of really good reasons why HVAC techs aren’t cutting on pipe in a building. Having the proper pipefitters/plumbers making those changes which doesn’t actually change any function is expensive, so I could see that money not being spent.
Looking at the final product, it looks like the HVAC folks could have acquired a larger vent grill and place the grill parallel to the tiles for cosmetic appeal even though the ducting wouldn’t take up the whole grill.
Same here! There are dozens of us! Dozens!
