Common Causes
- Leaky or disconnected duct joints

- Closed dampers somewhere in the system
- Insulation gaps around ductwork in the attic
What You Can Safely Check
- Check that all vents and registers throughout the home are open
- Note which specific rooms have weak airflow compared to rooms that feel fine
- If an attic space is easily and safely accessible, look for any obviously disconnected or visibly damaged ductwork without climbing on ceiling joists or handling the ductwork
