Can You Save Money by Closing Vents in Unused Rooms?

November 16, 2020

In an attempt to save money on energy bills, many people close vents in rooms they aren’t using. This is a mistake that can cost you money instead of saving it.

Closing Vents Causes Air Pressure Issues

Modern heating and cooling equipment is designed to work at a certain air pressure. When you close vents, you throw off the air pressure in your HVAC system. The air pressure will be higher than it should be, which makes your equipment strain against it.

When you close air vents, your HVAC system doesn’t work at a lower output. Instead, it works harder for no benefit.

More Repairs Bills

Since your HVAC system has to work harder when you close vents, it can sustain damage. The damage can include a cracked heat exchanger in your furnace or a frozen evaporator coil in your air conditioning system. Either situation will result in a very expensive repair bill.

Shorter Lifespan

Closing vents in unused rooms can shorten the lifespan of your HVAC system since it has to work harder. HVAC systems are expensive, so you want to get the most life out of them as possible.

Does Closing Vents Redirect Air?

It seems like common sense that when you close vents, the air will be redirected to another room in your home. Closed vents do redirect air, but it does so into unconditioned areas like your crawlspace and attic. The increased pressure forces conditioned air out through any inevitable gaps or holes in your ductwork.
