In the summer, if you have AC, the same thing is happening-heat rises, but this time you need the the vents open more on the upstairs so the cool air can work where needed most. Even without AC this can help, if you run the furnace fan, you can circulate the air from lower floors to the upper, just minimize the lower vents to maximize air flow to the upper floor.

If you play with them, you can adjust the bedrooms to individual comfort as well.

I’ve tried this and there is no noticeable difference besides the upstairs also being colder. The upstairs vents come off the main trunk so I think by block king maybe more just goes out chimney?
