Blocking air return vents with furniture

Can you block a return air vent?

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.

Is blocking a vent bad?

Fire Hazard. Perhaps the most obvious (and most dangerous) result of a blocked vent is that it will cause a fire. When you’re forcing your system to overwork, as mentioned in our first point, you put your furnace at high risk of setting on fire.

Does each room need a return vent?

Having several return vents (ideally one in every room , but even two or three is better than just one) creates consistent air pressure. If you have one return vent , your home is fine. Keep the doors to each room open so air can properly circulate.

Do return air vents go up or down?

It’s important to remember that hot air rises and cold air falls. In the winter you want the cold air to be drawn through the return registers leaving the hot air behind. By opening the lower registers and closing the top ones you keep hot air in and draw the cold air out.

What happens if there is not enough return air?

Where should a return vent be located?
