- I ran a rod through the circle vents from front to back. No blockage, but I can't see the probe from the AC unit box(!).
So, are the vents from the AC actually connected to the ducts?
QUESTION: Does anyone have a diagram of the ducting? There might be a place that was supposed to have been cut-through during construction, but wasn't.

For the duration of the summer, I've Macgyvered an external bypass from the unit into the circle duct at the kitchen with some aluminum gutter downspouts. Lots of airflow. Looks awful, but we'll survive the season.

Actually if you see the factory assemble the roof, there are not ducts per say. There is simply a lack of foam insulation blocks that form a rectangular channel in the roof insulation. Smoothing out the airflow into these channels is the way to make considerable improvement ins the turbulent air flow to the ceiling vents. Metal turning vanes are the best.
Generaly, the right side vents flow more air because of the CW rotation (as view fron the front) rotation of the squirl cage fan.
