I imagine this won't be something I can do myself. Just looking for anyone with experience having done this or gone through this himself. It seems like it could be rather labor-intensive if they have to go through the walls to repair something.
I have this very same problem and have been told it's because the installer didn't properly balance the load when they installed the ducts. Now, one side (top and bottom) of my house is very well cooled/heated while the other is not. It would not be cheap to correct, as it would require ripping out sheet rock and potentially replacing/realigning ducts.
However, I was told that by upgrading to a 95% furnace, that they would be able to install some sort of load balancer that could redirect more air to the other side of the house. I don't know if this would be possible to do without upgrading, for all I know they were just trying to sell me a new furnace. This would not fix the air leakage you have in the ducts, obviously.
