You probably have some poorly balanced and improperly routed/
fabricated ductwork. Although a duct fan might help, in the long run
if you get the system modified by knowledgeable professionals it will
work the way it should and by working right it will save you $$, maybe
even enough to pay for the rework in a few years. You might be missing
essentials like cold air returns, etc. Whatever you decide, good luck.
There are a lot of HVAC hacks out there.
