The two methods I used for rentals were (1) gently pull the edge of the carpet away from the baseboard and use the small gap between the tack strip and the wall, and (2) use the AC ductwork. For small places, there aren’t a lot of turns and longs runs in the ducts so it was the easiest way to get between front and back rooms, especially if there was a bathroom in between (also depends a lot on if the ducts are high or low).
