Today, it is almost impossible to imagine a world without air conditioning. The nicest thing ever is an HVAC system that functions effectively. They keep the temperature in your home or place of business comfortable. While most people know how to use their HVAC system, only a small percentage of homeowners are knowledgeable about how it works and what their air vents are.

If your home has central heating and cooling, the walls have two different types of vents. Let us clarify the differences between them for you.

Supply vents are the air vents that channel air into each area. The supply vents are where the conditioned air exits your furnace or air conditioner after passing through the ductwork. You can quickly identify these vents since they are the only ones from which you can feel conditioned air flowing.

What precisely do return vents do? These vents pull air from each room and send it back to the HVAC unit. Return vents are frequently larger than supply vents, so you won’t be able to feel the air entering them. When an HVAC system circulates air across space, the air pressure is increased. There are return vents to let the surplus air out.

How can you easily tell the difference between the main and return vents?
Take a piece of paper and hold it up to a vent to identify it. It is a return vent if the paper is drawn in the direction of the vent. Since the air is going into the ducts rather than out, return vents are often larger than supply vents and lack adjustable slats to guide airflow.

Where are the return vents?

Return registers are a pair of registers that are typically found at the ceiling and floor of rooms around your home. They are also known as high/low vents, ducts, and grilles. They have apertures with slats. These registers are recognizable because they are often larger than a supply vent.

You must keep both of those vents clean if you want to guarantee that the air in your home is clean. Regardless of how many vents you have in your home, each one is a crucial component of your system and needs the same level of maintenance.
