Nobody would blame you for doing everything you can to lower your energy bills. We all want to maximize comfort and minimize costs. Sometimes the best practices have to change with technology.

Let it be known: closing air vents does not save energy, assuming you are using modern forced-air heating and cooling systems.

Why People Think You Should Close Air Vents

The idea that closing air vents helps you save energy (or that it helps you avoid heating and cooling rooms that are not in use) has been around for decades. Part of this is because it probably did work well in old homes that lacked modern insulation and did not have the heating and cooling methods that we use today.

Otherwise, we might hope that by closing the vents in certain rooms that the conditioned air would make its way to the other rooms that still have the vents open. Unfortunately it just doesn’t work this way.

Why Closing Vents Is a Bad Idea

Essentially, you can’t stop air from moving. Your summer air conditioning and winter heat will still get pulled into the closed-off room. The air pressure will also push conditioned air into your floor cavities, attic and other gaps. You’ll be paying to heat and cool air that you won’t be enjoying.

Your home heating system also depends on running under normal conditions. By restricting airflow you could damage your heater by causing frozen patches or making it work on overdrive to move the conditioned air.

Alternatives for Energy Efficiency

The best step you can take is an upgrade of your heating system. An old furnace might only be 55-percent efficient, while new ones can be over 95-percent efficient! The technology has come a long way. Preventive maintenance also plays a pivotal role: Having your furnace cleaned and sealing all ducts will help the heating system function optimally.
