At Johnson Controls, we designed our Series 5 rooftop units to maintain temperature control without an intrusive footprint. If your internal space is limited, our flexible Series 5 units can not only be curb mounted on a roof, they can also be adapted for slab mounting at ground level or set on steel beams above a finished roof. This flexibility makes installing the Series 5 single-packaged unit quicker and easier, putting green, energy efficient cooling within reach of every building.
