A housing for a component (e.g., a heat exchanger) of a heating, ventilation, and/or air conditioning (HVAC) system is disclosed that includes one or more attachment flanges and/or one or more support flanges that are integrated into the housing. The disclosed housing reduces or completely eliminates the use of separate brackets and fasteners when installing components within the housing and/or when coupling the housing to other components of the HVAC system. By dramatically reducing or eliminating these separate components, the disclosed housing designs reduce the likelihood for installation errors, as well as delays due to misplaced brackets and/or fasteners during installation. Accordingly, the disclosed housing designs enable a cost-effective solution for reducing the cost and complexity of installing HVAC system components.
