Are registers and vents the same thing?


The terminology gets confusing, but yes. There are return air registers/vents that draw air back to the fan and should not have a way to close and supply air vent bring conditioned air back to the rooms and usually can be shut via a damper of some sort. Whether in the floor, on the wall, or in the ceiling they are all registers/vents.
