Answer:
Of course NOT, portable Ac can also be installed where there are no windows, infact in portable AC only the hose which is just 5" inches wide need to be vented out through a hole, but for through the wall AC you need tomake hole in the wall which can be as big as the entire unit. Portable AC are more energy efficient and less maintenance and no installation cost.
