The air return vent is an important component of your heating and cooling system. However, they are not pretty to look at, resulting in many people looking for ways to hide them.
You may be wondering if you can hide a return air vent without obstructing airflow. There are ways to hide your return air vent without obstructing airflow. It’s important not to block your return air vent because your HVAC system needs constant return air to work properly. A blocked air return vent will cause your system to lose efficiency and can cause premature failure of your HVAC system.

This does not mean you don’t have many options when it comes to hiding your return air vent. In this article, we will discuss ten ways that you can hide your return air vent without obstructing the flow of air to your heating and cooling system.
Is It Ok To Cover a Return Air Vent?
A return air vent is a critical component to making sure your heating and cooling system works properly. Blocking a return air vent can cause the HVAC system to not operate efficiently and can result in premature damage to the components inside your HVAC system.
Let me explain. The air handler (or furnace) portion of your heating and cooling system is equipped with a blower fan. This fan draws indoor air from the house through the return air vent. This air then flows over the evaporator coil where it is either heated or cooled prior to flowing into the supply ducts where it is distributed back into the rooms of your house.
How Much Space Does a Return Vent Need?
The minimum clearance is 6 inches of space in front of the air return. However, this is often not enough. I generally recommend that the return vent have a minimum clearance of 12 inches in front, 12 inches on each side, and 6 inches above and below the return vent. This allows for enough air space on all sides for the return vent to draw in air for proper operation.
Due to the downward slight on the louvers in the standard grille cover (some grilles do not have louvers) the most importance clearance space is in front of and below the return grille.
What happens when your return air vent is blocked?
When you block the return air vents you shut off all airflow into the heating and cooling system. This in turn stops the airflow to your rooms in your house. This causes stress on the blower motor and other HVAC components which causes the system to work harder and wear out faster.
What is the purpose of a return air grille
The standard return air grille is a metal louvered door that covers the opening into the return air duct. It also serves as a placeholder for the air filter in your return vent.
Typical metal louvered grille comes in various sizes and normally comes painted white. However, this is only a basic design. Decorative metal grilles or custom-built wood air return grilles can serve the same purpose and look better doing it.
Can you put furniture in front of a return vent?
Most people would tell you, no, you cannot put furniture in front of an air return vent. However, that is not entirely true. It often depends on what type of furniture you place in front of the return air vent.
For example, you can’t place a couch or chair or any piece of furniture that has a back into it in front of a return air vent because it will block all airflow into the return air vent.
Some furniture, such as end tables or shelving that is open on all sides and bottom would not obstruct the airflow into the return air vent. Custom pieces are fine too provided they meet these requirements.
The bottom line is as long as the furniture piece is open on all sides and the bottom allowing the return air vent to draw in air to the heating and cooling system unobstructed, it should be fine.
Let’s look at ten creative ways you can hide those ugly return air vents in your home.
10 creative ways to hide ugly return air vents
Ladder shelving has become popular in recent years. Ladder shelving is open at the bottom, has no backing, and is open on the sides. It leans up against the wall and either stands on its own or is secured to the wall at the top depending on the design.
Since ladder shelving is mostly open it creates enough space to allow for unobstructed airflow into the air return. The key is to not place baskets or clutter the shelves to the point that airflow is restricted.
Custom-built wood return cover
I found this idea on Pinterest from DesignerTrapped.com. It involved some minor carpentry skills however it is a do it yourself project. It involves building a custom wood frame and using decorative metal sheeting that is cut to fit.
On their website, they include a complete materials list and how-to videos. The finished product looks great.
Bifold louvered doors
Bifold louvered doors have been recently used as a decorative item to provide screening and create a focal point to hide areas in your home.
Some of these bifold louvered doors are antique while some are more modern designs. The key is that they are louvered and allow airflow through the louvers and on the top and sides.
Bifold louvered doors come in a variety of heights and widths. These doors often stand in place on their own by forming a Z or W pattern, depending on if you use 3 or 4 louvered panels.
If your return air vent is located in the room, such as a living room, a set of louvered may be just what you need while also providing a focal point of interest.
Much like the louvered doors, louvered shutters can be used to hide a return air vent without obstructing airflow.
These can be hung over the return vent like a picture would be or secured to the wall with hinges allowing you to open and close the shutters when it’s time to replace your air filters.
Blend-in with faux wainscoting
This method involves hiding the return in plain site by adding a chair rail and wood trimming the same size as the return around the room and painting the entire area white.
This method draws your eye to the woodwork rather than the return vent itself. The return vent fades into the background and is barely visible unless you know its there.
Decorative metal grill cover
This method is not necessarily a means of hiding the return air vent, it actually makes it a focal point in the room.
It turns a boring white louvered return vent door into a work of art. You can purchase these custom made return air vent grills online through Etsy and other custom shops.
These decorative metal grills are somewhat pricy but they are generally easy to install as a simple replacement for the existing door that you already have.
Narrow sofa table
We briefly mentioned furniture earlier in this article. One piece of furniture that you could use in front of a return air vent is a narrow sofa table or some people call it a foyer table.
These narrow tables usually are about 12 inches in width, have open sides and are open on the front and the back. This means you could place the table in front of a return air vent without blocking the airflow into the it.
Custom-built furniture pieces
These furniture pieces are built with masking the return air vent in mind. These pieces are limited only by your imagination. They can vary in size, shape and function.
Some examples can be found at Freshome.com. Like I said though, these are just ideas. Maybe you can find an old antique piece that could be modified if you don’t want to build from scratch.
Repurpose rubber door mats
This method has floated around the internet for a few years, but I’m surprised at those who’ve not seen it.
The premise is to mount a think rubber grated floor mats over the existing return vent. From afar this method looks good, but I’m not a fan of it close up. In my opinion, it just doesn’t look very professional.
The other problem is that these won’t cover all air return vents. Typically these rugs are about 18″ x 30″. Many return vents are over 20″ wide.
Blend the vent in with paint
As Nike says, Just Paint It! Well, you know what I mean. One way to disguise the return air vent is to paint it the same color as the wall. That painting the return air vent grille, it blends into the background making it last noticeable.
There are some drawbacks to this method as opening and closing the door on a regular basis to change your air filters could cause the paint to chip off. So don’t use latex paint. You’ll need a paint designed for metal surfaces.
If you can get some tintable paint made for metal surfaces, you can obtain a smooth durable finish using a paint sprayer.
If matching paint isn’t an option, try using a metallic copper, pewter or black paint to give a basic white grille some character.
By now, I hope you understand the importance of the air return vent but also understand that you can safely hide the return air vent. You just need to plan out your project and make sure you don’t obstruct the airflow to the return vent and allow for access to replace the air filter.
