Are the existing ducts large enough to move the new systems air flow at an acceptable velocity?

Loved it thanks for the video Ed! I wish all ductulators would remove the 0.1 as recommended setting. I'm fortunate to be in basement country (primarily), I can understand that low velocity may be an issue in humid climates w/ ducts in the attic (sweating of the insulation layer), but aside from that it seems folks don't understand that you can increase the velocity at the boot to achieve a good face velocity / throw! 👍
