Is it OK to cover air vents?
You could mess with the air flow. Just because you cover the vent, it doesn't mean your HVAC system knows that. It will keep pushing air to those vents, and if they're closed, you could cause a buildup of air pressure and insufficient airflow which could damage your system.

Why do houses in the South have their air vents on the ceiling?
While living in the south, you may have noticed that extreme heat is more common than extreme cold. If you remember basic science, you'll know that hot air rises, and cold air sinks, making ceiling vents the delivery location of choice for places that often experience warmth and humidity.
How to improve airflow in a room?
