Hello, there can be many causes, usually its not enough air flow to the upper floor, Compare the air flow out of each vent on each floor and tell me if the upper floor is getting air flow but maybe about half as much as the other floors, use a thin strip of tissue as an air flow gauge of sorts.

Tell me where the air handler(s)/ furnace(s) are located.. that will tell me a lot about the potential problems
