Bard part 137-188 is an OEM return air fill piece used in select Bard wall mounted HVAC cabinets to close off and guide the return air path so the blower pulls air through the intended return opening and filter area. When a return air fill is missing, bent, or corroded, units can develop bypass air, rattles, and reduced airflow across the indoor coil. Replacing it with the correct Bard factory part helps restore proper cabinet airflow management and fit without guesswork. Confirm compatibility by matching 137-188 to your unit model and parts list before ordering.
