• Filter Door Assembly - Gray

The Bard 552-137-4 filter door assembly is an OEM replacement access door that covers and secures the return air filter compartment on compatible Bard wall-mount HVAC units. A properly fitting filter door helps keep the filter seated so air is pulled through the filter instead of bypassing it, which supports cleaner coils, steadier airflow, and easier routine filter changes. If your existing door is bent, missing, or not latching correctly, replacing it with Bard part 552-137-4 restores the correct fit and service access expected from factory parts.
