Coleman RV rooftop air conditioner runs but airflow inside the RV is weak.

Safety: Disconnect RV power before removing the interior shroud.

• Clean filters: Remove and clean or replace the return air filters in the ceiling assembly.
• Inspect vents: Ensure all ceiling vents are open and not blocked by furniture or covers.
• Check ducting: With the shroud removed, inspect the flexible ducts for kinks or collapse. Straighten or replace as needed.
• Clean blower wheel: If accessible, clean dust buildup from the blower wheel to restore airflow.

Note: Some RVs have poorly designed ducting; airflow may be inherently limited.
