A multi-row heat exchanger coil includes a first row of coil, a second row of coil positioned generally parallel to the first row of coil, a bent portion fluidly communicating the first and second rows of coil, an interior space formed between the first and second rows of coil, and a mounting assembly. The mounting assembly includes at least one connection member configured to connect the first and second rows, thereby securing the first and second rows of coil to each other, a mounting member configured to prevent airflow from exiting from the interior space at a side of the multi-row heat exchanger coil, and fastening mechanism configured to attach the mounting member to the connection member.
