Can a Commercial Rooftop Unit be installed on the ground instead of the roof?

Yes. Some commercial packaged rooftop units can be installed at ground level when the equipment is designed for horizontal airflow rather than vertical rooftop discharge. These horizontal-flow units require adequate space, a stable mounting surface, proper ductwork connections, and sufficient clearance for airflow and servicing. Always verify the manufacturer's installation requirements and local building codes before selecting a ground-level installation.
