I need to move around some duct work in my house to make way for a closet and to rebalance the system. The side of the house far from the furnace is much colder. I’m just hoping for some basic guidelines such as:
1) Is there any negative circulation effect to move registers from the wall to the floor. I could eliminate a 90 turn, but the heat/cold air would blow up instead of across the room.
2) To force more air to the far side of the house, is it better to partially close registers in the hotter side of the house, or is it worth it to disassemble ducts and install dampers near the furnace.
3) My second floor only has two returns (1 each bedroom) but there are two supply vents in each room and one in the hall and one in the bath. That’s 6 supply vents for 2 returns. I suspect it makes sense to stick a return at the top of the staircase. Thoughts?
