What do you do when running a return air duct and something gets in the way? Look what these people did.
The return air grill is in the ceiling and runs through the attic to the return air closet. They then used duct board to finish the duct bringing the return air to the air handler. One problem - there is a breaker panel in the closet, so they cut down the size of the duct to less than 50% and “squeezed” the duct around one side of the panel.
It makes you wonder what some people are thinking.
