Trunk and branch ductwork. Branch locations.

This one covers placement of branches on the trunk line. This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.

Let’s say we have a house that has register buckets evenly distributed throughout the attic space to every room. We have an ahu that is in the middle of the house. The plenum is facing one way horizontal left. Would air be able to flow good to the right of the plenum to feed the right side of the house vs the left

Seen this occur when a ductboard "PIE" wedge is used. Poor airflow. These pie wedges are terrible.
