What is the advantage of buying portable air conditioner?

Question:vs traditional window air conditioner

Answers:
Portable air conditioners are useful if you have windows that are unsuitable for window units due to size, shape or placement, or you don't want to give up the window for the season. A portable a/c still has to be vented to the outdoors, so in addition to being more expensive to buy, they are sometimes an expense to install.
