Those designed and intended to be installed that way are designed for that.
A package unit is not, neither is a regular condenser unit.
That's like taking a "window unit" and installing it through a "wall" ... the wall block much/most/all the vents, whereas units designed and intended to be installed through a wall have the vents designed for that.
