A:Answer Heavy enough where you’ll need a strong man! As a woman who average sized, there’s no way I could lift this on my own. My boyfriend put it on a cart with wheels to make it easier to maneuver. It took both of us to put it into the window. It’s a great ac unit. My house is 998 sq and it does the entire floor. Love the auto shut off to save electricity. Only issue we had was the screws that came with it, weren’t the correct ones. We had to buy them.
