Micah Sherman agrees: “Closing vents in unused rooms can create pressure issues… forcing [the HVAC] to work harder and potentially leading to damage” tomsguide.com. In plain terms, your furnace or AC is trying to push the same amount of air through fewer open vents, so it overheats, freezes up, or simply wears out sooner tomsguide.com.
