An air return, also known as a cold air return, is the opening in a house through which air is drawn back into the heating and cooling system. The size of the air return is important, as a too-small opening will not allow enough air to circulate and a too-large opening will cause the system to work less efficiently.
An air return, also known as a cold air return, is a duct that is used to return cold air to a furnace or air conditioner. The size of an air return is important, as a too-big air return can result in reduced efficiency and increased energy costs.
The size of an air return is typically determined by the size of the furnace or air conditioner.
A furnace or air conditioner that is too small will not be able to properly heat or cool a home, and a too-big air return will result in wasted energy. The ideal size for an air return is typically about 14×20 inches. However, the size of an air return can vary depending on the layout of a home and the specific needs of a furnace or air conditioner.
If you are unsure about the size of your air return, it is best to consult with a professional.

Symptoms of not enough return air
If your home isn’t getting enough return air, you may notice some Telltale Signs. The air in your home may feel stuffy, and your windows may be fogging up. You may also notice that your furnace is running more often than usual.
These are all signs that your home isn’t getting enough return air. One of the main reasons for not enough return air is a blockage in the return air ducts. This can be caused by a build-up of dust and debris, or by a closed damper.
Another reason for not enough return air is a leak in the ductwork. This can be caused by a hole in the ductwork, or by a loose connection. If you’re not getting enough return air, there are a few things you can do.
First, check the return air ducts for blockages or leaks. If you find a blockage, you can clean it out or remove it.
Return air box size
If you’re considering buying a new return air box, you may be wondering what size you need. The size of the return air box will depend on the size of your furnace. A standard size return air box will typically be between 24×24 and 30×30.
However, if you have a larger furnace, you may need a larger return air box. Return air boxes come in various sizes, so be sure to measure your furnace before making a purchase.
How to increase return air flow
If your HVAC system isn’t working as efficiently as it should be, it could be because the return air flow is insufficient. There are a few things you can do to increase the return air flow and improve the performance of your HVAC system.
One way to increase return air flow is to make sure the return air ducts are clear and free of any obstructions.
If the ducts are blocked, the air flow will be restricted and your HVAC system won’t work as efficiently. Another way to increase return air flow is to increase the size of the return air ducts. If the ducts are too small, the air flow will be restricted.
You can either replace the existing ducts with larger ones or add additional ducts to the system. Finally, you can also increase return air flow by increasing the speed of the blower fans.
How to tell if return air is working
If your furnace has a return air duct (most do), it’s important to make sure that it’s working properly. A return air duct is a vital part of your furnace system, and if it’s not working properly, your furnace will have to work harder to heat your home – which can lead to increased energy bills.
There are a few easy ways to tell if your return air duct is working properly.
First, take a look at the duct itself. If it’s covered in dust or debris, it’s probably not working as efficiently as it could be. Second, take a look at your furnace filter.
If it’s dirty, it’s likely that your return air duct is also dirty. Finally, if your furnace is running constantly, it’s a good indication that your return air duct is not working properly. If you suspect that your return air duct is not working properly, it’s important to have it checked out by a professional.
How big should return air vents be?
There is no definitive answer when it comes to the size of return air vents, as it will depend on a number of factors such as the size of the room, the type of heating and cooling system in place, and the level of insulation. However, as a general rule of thumb, it is typically recommended that return air vents should be around 20-30% of the size of the supply air vents. This will ensure that the room is evenly heated or cooled, and that the air flow is not restricted.
Should supply and return ducts be the same size?
There is no definitive answer to this question as it depends on a number of factors specific to each installation. However, in general, it is advisable to use the same size ductwork for both the supply and return sides of your HVAC system. This will ensure optimal airflow and prevent pressure imbalances that can lead to comfort issues or system damage.
What size return do I need for a 3 ton AC unit?
If you have a 3 ton AC unit, you will need a return that is at least 36 inches wide and 24 inches high. This will allow for proper airflow and will prevent the unit from overworking.
What happens if return air is undersized?
If return air is undersized, it can cause a number of problems. One is that the furnace will have to work harder to heating the home, which can lead to increased energy bills. Additionally, it can cause the furnace to overheat and shut down prematurely.
An air return, also known as a cold air return, is a duct that helps circulate air in a home. It pulls air from rooms and returns it to the furnace or air conditioner to be filtered and re-circulated. Some people believe that an air return can be too big, but there are actually a few benefits to having a large air return.
One benefit of a large air return is that it can help improve air circulation in a home. If a home has poor air circulation, it can be stuffy and uncomfortable. A large air return can help to solve this problem by pulling more air from the rooms and circulating it back to the furnace or air conditioner.
Another benefit of a large air return is that it can help to improve the efficiency of a furnace or air conditioner. When an air return is too small, it can restrict the airflow and make the furnace or air conditioner work harder to circulate air.
