If the ductwork isn't wrapped with insulation that would also help, both summer and winter. The dampers that are part of the registers are really only to shut off rooms that you don't use, using them to limit the volume of air will create a lot of noise and have less effect getting the air to the other rooms. That is why you want to install them as close to the furnace/heat exchanger as possible.

What do you think of the flexi ducting? I have recently (well in the last 3 years or so) installed a few systems and used the flexi duct in all of them. Seemed pretty good, and was super easy to do. I could easily do a single story house in a day if I was swapping out the old ducting for this... As long as someone could figure out the correct sizes for the various rooms...
