Portable air conditioners are the best options for those residing in smaller spaces such as small apartments, rooms, and small condos. They are the best for such apartments because they are designed to stand on their own. This makes it different from traditional air conditioners, which cannot stand on their own. Moreover, portable air conditioners do not need installation, and this implies that almost anybody can use it without help. Perhaps, the best selling point for this type of unit is that they can be used anywhere, as you can just take it with you anywhere you go.
