Assuming that your furnace is sized appropriately and your fan is capable of pushing air through the longest (equivalent length not necessarily actual length) leg of your HVAC system (I'm willing to be it's your kitchen because it's the coldest) you can adjust the dampers inside of the registers of the other rooms in the house to balance the legs. Basically for free you could go to the hottest room in the house and close the register nearly all the way second hottest room and adjust it 7/8 open etc...
This would essentially make it so that all of the legs have the same pressure and would flow the same volume of air through them.
