Thus, the unit is creating a vacuum inside the room; air infiltrates from outside into the room to reduce the vacuum. It's like running AC with the window open. Window units do not suffer from this flaw.

We run one in our enclosed lanai and I find it very efficient it cools the room down rapidly. My only complaint is that it is loud.
