Main Que: What are wall mounted package units? Are they like huge window air conditioners?

Answer: In some sense, I think I can agree with you that they are sort of huge window air conditioners. But not really either. Wall mount package units are big commercial air conditioners that look like standing upright ptac units. They are installed directly on the exterior wall with the vent going right in the interior. A lot of them are used in schools and small one storey offices. These systems are really powerful and energy efficient as well.
