Ducts in the attic (oven) is insane… yet common.
Flex ducts…. In the attic…. Horrible efficiency!!! Never in my homes
They should only be used for the final few feet, but get used for everything now. The air flow losses are huge, and then they wonder why the AC doesn't work all that well. Not to mention that they have about R3 insulation.
Huge waste of energy in pumping losses and thermal losses thru the duct.
