What Is the Purpose of My AC Return Air Vent?

A properly functioning HVAC system is essential to a comfortable home. While many people know how to operate their AC system, very few people know how it actually works. Your AC’s return air vent is a critical component of an HVAC system and serves several purposes. Not only do return air vents maintain your home’s air pressure and filter out debris, they can also serve to save you on energy costs and expenses, which is important here in hot and humid Gainesville, Fla.

Maintaining Air Pressure

An HVAC system is basically a recirculating pump that works by heating or cooling air and then pumping it into a home. As conditioned air is pushed in, the air already in the home needs a place to escape. Return air vents serve this purpose by helping to pull in the air and putting it back into the system. This is what maintains proper air pressure in a home.

Filtering Out Debris

As air circulates through a house, it picks up pollen, dust and airborne debris. These particles can damage an HVAC system—as well as your health—so it is critical to filter them out before the air is returned to the unit. Return air vents are often equipped with a specially-fitted filter that serves this precise purpose. In order to maintain an efficient and functional system, this air filter should be changed or cleaned on a regular basis.

Save on Energy Costs

In order to function at optimal efficiency, an HVAC system must be properly sealed so no air is able to leak out. In a properly sealed system, the return air vent is critical to saving money on energy costs. Because the return vent takes already heated or cooled air from the building and returns it to the system, this air will be closer to the desired temperature than air taken from outside. Therefore, it will not require as much energy for the system to maintain the target desired temperature. Ultimately, this can lead to huge savings when it comes to energy expenses.

Importance of Proper AC Return Vents

When air return vents are not working properly, the entire HVAC system suffers. Blocked vents can hinder airflow and cause the system to run inefficiently. Also, improperly placed vents can affect how a building maintains its temperature.

In the infographic to the right, you can see that leaks in return vents are a common duct problem. Not only will this issue make your home less comfortable, but you will likely notice an increase in your monthly energy bill costs.
