3. It probably has to do with how the unit is vented.

Window units often have vents on both the sides and the rear of the unit. If so, they need to be modified if installed through a wall.

In a wall installation, those side vents would be blocked and the result might be a dangerous heat buildup inside the unit. The good news is that other than the venting, window and wall units are essentially the same.

It should be possible to find a unit that has all the features you want that is also safe to install through the wall.
