I finally got the ducting in the attic replaced. Took a long, long time. I am more flexible and patient than I would have imagined. Think hot yoga with jeans, knee pads, nails above your head, a respirator and lots of insulation all over you. When I say hot, I mean 10 minutes and your clothes are totally soaked (like you jumped in a nasty, salty lake).
But we are cool and breezy in all the rooms now. The above photo shows just one section of damage. I put the paper in there to better illustrate the hole. The big one is about 4 1/2 inches wide and 3 inches tall. All the ducts were like this every few feet they had a series of holes. Some small, some large, some looked like they had been shot at. But now all that cold air is blowing into my bedroom. And it is good.
