My neighbor is enclosing his lanai and had his a/c unit was tested and his unit is the correct size to cool his lanai. I dont know if they are running a new duct or splitting from another duct. This work is being done with building permits.

I don't know if Mr. Grampy II is correct: Running a duct work from your existing AC is considered an illegal hook up. It would not pass inspection. If you did it on your own if would cause a problem when you try to sell your home or pass the home on to your heirs.
