The Bard 552-179 Filter Door Assembly is an OEM replacement access door used on select Bard wall mount HVAC units to secure the return air filter area and allow quick filter checks and changes during routine maintenance. A properly fitting filter door helps keep the filter seated correctly, reduces air bypass around the filter, and supports consistent airflow across the coil for dependable heating and cooling performance. Confirm compatibility by matching the part number to your Bard model and parts list before ordering, especially if your unit has had cabinet or return air modifications in the field.
Please call for available options or find replacement parts.
