Should you cover air vents?
While you should never fully close air vents, you may increase energy savings by partially closing one or two outlets in your home that are farthest away from your furnace. Partially closed vents still allow air to flow properly through the HVAC system, which prevents overheating and added pressure to the ductwork.
What are air vent covers called?
grille

Is covering an air vent a fire hazard?
Fire, Freeze and Financial Hazard When a vent is blocked, less cool air flows across the heat exchanger, which then overheats, and expands, and cracks. It’s unlikely but not impossible that blocking a heating vent and causing the furnace apparatus to overheat could cause a fire.
Is it bad to cover vent with couch?
