1. A diffuser assembly for a heating, ventilating, and air conditioning (HVAC) system, comprising:
an outer frame comprising a first inlet configured to receive an air flow;
an inner frame disposed within the outer frame and forming a first flow path for the air flow between the outer frame and the inner frame, wherein the inner frame defines a second flow path for the air flow through the inner frame; and
a damper assembly configured to transition between a first configuration to enable discharge of the air flow from the diffuser assembly via the first flow path and a second configuration to enable discharge of the air flow from the diffuser assembly via the second flow path, wherein the damper assembly comprises:
a damper plate configured to block flow of the air flow via the second flow path in the first configuration; and
a perimetrical sleeve spaced apart from the damper plate and configured to block flow of the air flow via the first flow path in the second configuration.
