An air conditioning system. The system comprises an indoor section and an outdoor section arranged in side-by-side arrangement. The indoor section includes an indoor tangential fan having an axis aligned in a first direction, an indoor heat exchange coil, and a supply air aperture which longitudinally extends in the first direction and avoids line of sight noise transmission from the indoor fan. The system includes an axis commonly supporting and operably coupling the indoor fan and the motor, and a scroll housing within the indoor section and arranged about the indoor tangential fan. The indoor tangential fan, motor and axis are assembled to form a first module, the scroll housing forms a second module and the first module is independently removable from the second module without the necessity of disengaging any connection between the first and second modules. The system includes a fan support bracket supporting a first end of the axis, and the motor supporting a second end of the axis. The fan support bracket includes a bearing assembly rotatably supporting the axis and having a flange; a support bracket including a flange support matingly adapted to engage the flange, a clip adapted to engage a lower end of the bearing assembly support, and an axis aperture adapted to receive the first end of the axis. The system includes a module arranged about and supporting the indoor coil, and a horizontal guide allowing the coil and module to be removed in a horizontal direction.
