I think the system is marginally designed and I might modify it. I just don't want to make it worse! I think shortening the return flex is a good idea, and performing a good cleaning on the intake vents, and trying to modify them to get a good path to the intake is key. I'm not sure if they made this so long and convoluted on purpose though? Seems ass-backwards to me - shouldn't you want a return path with as low restrictions as possible?

The longer the flex run, the more static pressure the system will see due to the corrugations in the flex duct, so shortening the length of the return wouldn't be bad. What size is the furnace/Air conditioner. I'll PM you my number if you'd like to talk shop a bit. Mind you, I haven't done this stuff in years but it's not too hard to figure out.
