Clean Vent Housing Interior

What happens here

Visually inspect the inside of the vent housing, which may still contain dust and debris that accumulated over time or fell during fan removal. Use a vacuum cleaner with a brush attachment, a damp cloth, or the electric duster to clean the internal surfaces of the vent housing thoroughly. Remove any remaining dust, dirt, or spiderwebs from the walls and corners of the enclosure. The narrator mentions cleaning it out, implying a quick but thorough process.

Goal: After cleaning the fan assembly, the interior of the vent housing must also be cleaned to remove any remaining dust and improve overall airflow.
