Window units are installed directly into a windowpane or wall in a home, and they work by removing hot room air and sending it outside. They need to be permanently mounted to the window or wall.
Portable air conditioners are versatile because they can be moved from room to room, but they also need to vent hot air out of the home. In addition, because portable ACs are on wheels, they can be easily stored when not in use.
Unlike a window unit, a portable air conditioner can solve all these problems instantly. First, plug your unit into any wall outlet and turn it on.
Then, the cool air will immediately start flowing through your home—and you won't even have to worry about moving anywhere this equipment or dealing with a heavy, cumbersome window unit.
