Which of the following should be included in the inspection?

Through-wall air conditioners should be included in the inspection because they are considered part of the building's mechanical systems. These units are installed within the wall and have a significant impact on the property's interior air quality, comfort, and energy efficiency. Inspecting these systems is critical because they can reveal issues such as improper installation, inadequate drainage, or wear and tear that could lead to more significant problems or inefficiencies.

In contrast, items such as shutters, portable kitchen appliances, and blinds and draperies are generally not integral to the structure or essential systems of the home. While they may be visually assessed for the sake of completeness, they do not typically carry the same level of importance as built-in systems like through-wall air conditioning units, which require more thorough evaluation during an inspection.
