Your furnace sends hot air through the ducts to warm up each room individually. The channel of hot air flows into the room through a heat register, or vent, on the floor or the ceiling. If the register is blocked, your heating system cannot run efficiently, often resulting in damage to the furnace components, including the blower motor and pump. Hot air flowing out of your heater vents can even damage the items sitting too close to the registers.
