thanks for this info. We had the same problem last spring when we turned on the A/C the house smelled like pee for a few weeks until the moisture in the ducts was gone.
I will turn on my fan tonight and let it run for a bit, and then tape my ducts shut with plastic wrap. It is too dang hard to remove and replace the vents, it ends up disturbing the ducting in the attic making it very hard to get the screws back in.
