Airflow & Comfort · Article 15 of 25
Quick answer: Closing vents is not a dependable substitute for a properly designed zoning system.
Understanding the issue
Closing vents is not a dependable substitute for a properly designed zoning system. Restricting the airflow your system expects can create operating problems. If you want room-by-room control, the equipment and duct arrangement should be evaluated together.
What homeowners can do
Keep normal supply and return paths unobstructed unless a qualified technician has recommended a specific adjustment for your system. Avoid closing most registers in an attempt to force more air into one room. Note which spaces are uncomfortable instead.
