Why You Should Never Close Your Vents

At Hedrick's Service Now, something we can never stress the importance of enough is that closing your vents in unused rooms will not save you money. Many homeowners tend to fall for the HVAC myth that you’ll save energy by closing the vents in vacant rooms in your house, but it’s actually the complete opposite.

If you tend to close your vents when your HVAC system is on, we’re about to share with you some reasons why you should stop and how you’re actually wasting energy and money.

Restricted Airflow

When your HVAC system is turned on, you want to evenly distribute the airflow throughout your home. When there are certain vents closed, specific rooms in your house could feel colder or warmer than others, when the only reason is because a few vents are closed. Additionally, your HVAC system won’t know there are closed vents, so it will work even harder to distribute the airflow that is being restricted, resulting in wasted energy and higher utility bills.

Wasted Energy

Speaking of wasted energy and higher utility bills, that’s exactly what will happen when you close your vents. Since your HVAC system doesn’t know when the vents are closed, it will keep producing the same amount of air it typically does. Closed vents create an imbalance in your system’s airflow, which will cause your HVAC system to overwork itself, wasting energy.

Causes Mold

When your vents are closed, air builds up in them, causing condensation due to the low temperatures in the room. Everyone knows that condensation or any type of standing water is a recipe for mold and mildew growth, so always try and make sure your vents are kept open to avoid this issue. Once mold forms in your ductwork, you’ll need professional service to remove it.
