Air Return Vent Questions
Not everyone’s calling in life is to be an HVAC expert, and there is no shame in that. But if you’re a homeowner, or even renter, it’s important to have a base understanding of what’s going on in your heating and cooling system so you can care for it properly and even diagnose minor issues before having to call in a pro.
So buckle up as we answer the most frequently asked questions regarding air return vents!
What Is An Air Return Vent?
An air return vent is the hole through which the air in your home is sucked and sent back, or returned, to the HVAC system. This is why you won’t feel air coming into a room through an air return vent—that is the job of another type of vent entirely (air supply vent). Return air vents are generally larger than other vents and there are fewer of them in the home, usually located in central, larger rooms to more efficiently pull air from the home and into the system. Return air vents are often located on a wall, rather than the floor or ceiling.

What Is An Air Supply Vent?
An air supply vent is the opposite of an air return vent—its job is to supply your home with air, either or heated or cooled, from the HVAC system or furnace and through the ducts to the vents. These types of vents can be found on the floor, ceiling, or wall of almost every room in a home to provide consistent airflow throughout.
What’s The Difference Between A Vent Cover And Vent Register?
The difference between a vent cover and vent register is functionality. While both work to prevent larger bits of debris from entering your air ducts while still allowing for proper airflow, only a vent register has the ability to change airflow direction or close the vent partly or completely with the use of a damper—a small lever that can move back and forth.
Why Are Air Return Vents Important?
Air return vents are essential to your HVAC system. They are what pull air from the home, return it to the system, filter it, and help maintain comfortable temperatures throughout your house. They also help remove excess moisture from the air, preventing your home from feeling muggy or dank.
Where Should Return Air Vents Be?
Air return vents are often located near the center of a home, generally with one return air vent per floor. This allows the air to circulate efficiently throughout the home and back to the HVAC system. Return air vents are usually found in the lower wall of a room or hallway.

Do You Need A Return Vent In Every Room?
An air return vent in every room of the home is becoming more common in modern building codes. In homes older than 10 years, there is usually just one return air vent per floor or large section of a home, located centrally so that the suction can pull air efficiently from every corner of the level.
How Do I Know If My Return Air Vent Is Working?
Because the return air vent works to suck air from a room and back into the ducts, you can try this simple test to see if it is working: take a tissue or thin paper and hold it in front of the return air vent, about 6” away. If the paper is being pulled toward the vent, you know it is doing its main duty.
Is It Okay To Cover A Return Air Vent?
While you should have a filter on your air return vent to prevent too much dust or moisture from entering your air system and recirculating back to you, you should never actually cover a return air vent. Keep furniture and even curtains at least 10” away from the vent opening in order to allow for proper air flow. It’s important to keep the area in front of your return air vents clear for a few reasons. If you don’t, it reduces the efficiency of your air system and causes it to use more energy. This can not only increase your bill but can even wear out your system faster than necessary causing the need for repairs or even replacement.
Can You Put A Couch Over A Floor Vent?
It’s not a great idea to cover a floor vent, even with a couch that has legs lifting it up off the floor. You want a good 10” between large, dense furniture for optimal airflow from a floor vent or any other vent. Covering a floor vent with furniture will simply diminish the efficiency of air flow and temperature control in the space.
Should I Block Cold Air Return Vents In The Summer?
You should never block your air return vents. Period. However, if you’re looking to keep your home cooler in the summer, you can try closing lower supply vents and keeping upper ones open, allowing cooler air temperatures to come in from above and sink throughout your house.
Should Return Air Vents Be Open Or Closed In Winter?
Once again, NEVER close a return air vent. If you have operable cold air SUPPLY vents in your home, you can close upper supply air vents and keep lower return air vents open in the winter to keep your home cozy while allowing your heating system to work efficiently.
What Happens If There Is Not Enough Return Air?
As mentioned earlier, getting enough return air to your HVAC system is crucial for its proper functioning. When there isn’t enough air, it strains the system but can also prevent latent heat from getting to the evaporator coil causing it to freeze, which can cause even further damage.

Can You Have Too Much Return Air?
Too much return air coming through your system isn’t much of an issue because the fans and ductwork working to get that air back into the system only pull with so much force to make the HVAC system work correctly. The issue comes when the air returns are unfiltered, allowing dust and gunk to get into the heating and cooling system coils, reducing their efficiency and overworking your system while recirculating less than clean air to your home.
Does My Air Return Vent Need A Filter?
YES. As just indicated, having a clean filter on your return air vents at all times is key to an efficient system that will circulate nice clean air into your home. Make sure you’re following recommended procedures for switching out filters at regular intervals (usually every few months, depending on the type and manufacturer).
