Closing the air vents to unoccupied rooms sounds like a good idea; after all, you don’t want your AC to run unnecessarily. However, what sounds good in theory has an adverse effect on your AC and your energy bill in practice. Consider the following points.

Closing the Vents Contributes to Energy Loss

Your air conditioner runs at a single speed in order to cool all rooms simultaneously. When it’s hindered from doing this, the air it sends out will turn back and most likely seep out through leaks in the ductwork. That does no one any good, and your AC will have to run longer to reach the set point. Besides that, closing the vents increases air pressure, which can put wear on the AC motor.

Wearing Down the Air Conditioner

Remember that though you close the supply vents to your upstairs rooms, the return vents stay open, and these still send air into the AC. It could be the warm air, in which case the AC will keep running until there’s no more of that warm air, but since you’re not cooling those rooms, the warm air will linger. On the other hand, the return vents could send in cool air from surrounding rooms, in which case those rooms will need extra cooling. In both cases, you’re wearing out the system through overuse.
