3. The partition wall of claim 1 , wherein each of the one or more panels is slidably coupled to the frame.

4. The partition wall of claim 1 , wherein each of the one or more panels is snap-fitted to the frame.

5. The partition wall of claim 1 , wherein each of the one or more panels comprises a first side and a second side, and wherein the flange comprises one or more flanges extending from the first side, the second side, or both.

6. The partition wall of claim 5 , wherein each of the first side and the second side of each panel includes one or more cavities configured to receive a respective one or more flanges from another of the one or more panels.

7. The partition wall of claim 5 , wherein a channel is defined by the first side of a first panel of the one or more panels, the second side of a second panel of the one or more panels adjacent to the first panel, and the one or more flanges extending from the first side or the second side of the first panel or the second panel.

8. The partition wall of claim 7 , wherein a stiffener is disposed within the channel between each of the one or more panels.

9. The partition wall of claim 8 , wherein each stiffener is circumscribed on three sides by:

the second side of the first panel of the one or more panels;

the first side of the second panel of the one or more panels adjacent to the first panel; and

the flange.

10. A heating, ventilation, and air conditioning (HVAC) unit, comprising:

a housing configured to provide support for one or more components of the HVAC unit; and

one or more partition walls extending within or around the housing and configured to separate the housing into two or more internal volumes, wherein a partition wall of the one or more partition walls comprises:

a frame coupled to the housing and defining a perimeter of the partition wall, wherein the frame comprises a first support member, a second support member, a first cross rail, and a second cross rail; and

one or more panels extending within the frame, wherein each respective panel of the one or more panels comprises a flange coplanar with a corresponding first surface of the respective panel relative to a plane extending along a height of the respective panel, wherein the flange comprises a first surface configured to abut an additional first surface of an adjacent panel of the one or more panels along the plane and a second surface opposite the first surface and configured to abut the frame along the plane to provide substantially air-tight engagement there between.

11. The HVAC unit of claim 10 , wherein each panel of the one or more panels is slidably coupled to the first cross rail, the second cross rail, or both.

12. The HVAC unit of claim 10 , wherein each panel of the one or more panels is snap-fitted to the first cross rail, the second cross rail, or both.

13. The HVAC unit of claim 10 , wherein at least one of the one or more panels is coupled to an insulation layer.

14. The HVAC unit of claim 10 , wherein each of the one or more panels comprises a first side and a second side, wherein the first side and the second side of each panel includes one or more cavities configured to receive one or more flanges, and wherein the one or more flanges extending from a first panel of the one or more panels engages with the one or more cavities of a second panel of the one or more panels adjacent to the first panel to provide an additional substantially air-tight engagement there between.

15. The HVAC unit of claim 10 , wherein each of the first support member and the second support member comprises:

a port having a surface configured to abut a first side or a second side of the one or more panels; and

one or more receptacles configured to receive one or more flanges extending from the first side or the second side of the one or more panels.

16. A housing configured to enclose one or more components of a heating, ventilation, and air conditioning (HVAC) system, comprising:

a base; and

one or more frames coupled to the base and configured to define a perimeter of one or more partition walls extending within the housing, wherein the one or more partition walls are configured to separate the housing into two or more internal volumes, and wherein each of the one or more partition walls comprises:

one or more panels extending within a frame of the one or more frames, wherein each respective panel of the one or more panels comprises one or more flanges coplanar with a corresponding first surface of the respective panel relative to a plane extending along a height of the respective panel, wherein a first flange of the one or more flanges is configured to slidably engage an additional first surface of an adjacent panel of the one or more panels and the frame along the plane such that the first flange is captured between the additional first surface and the frame to provide substantially air-tight engagement there between.

17. The housing of claim 16 , wherein each of the one or more panels comprises:

a first side and a second side each configured to abut another of the one or more panels or the frame, wherein the first side of each panel comprises:

the first flange of the one or more flanges extending in a first direction coplanar with the corresponding first surface of the one or more panels;

a second flange of the one or more flanges extending in the first direction and positioned closer to a stiffener relative to the first flange;

a first cavity configured to engage with an additional first flange from another of the one or more panels; and

a second cavity configured to engage with an additional second flange from another of the one or more panels.

18. The housing of claim 16 , wherein each frame of the one or more frames comprises a first support member, a second support member, a first cross rail, and a second cross rail, wherein each of the one or more panels is configured to engage with the first support member and the second support member to provide the air-tight engagement there between, and wherein each of the one or more panels is configured to slidably couple to the first cross rail, the second cross rail, or both.

19. The housing of claim 18 , wherein each of the first support member and the second support member comprises a port having a surface configured to abut a side of the one or more panels, and wherein the port comprises one or more receptacles configured to receive and engage with the one or more flanges from the one or more panels.

20. The partition wall of claim 8 , wherein the flange is a first flange, and wherein each respective panel comprises a second flange positioned closer to the stiffener relative to the first flange.
