Summertime means pool time, heading to the beach, or relaxing lakeside afternoons. It does, however, imply that you are excessively hot. Therefore, finding a solution to stay cool could be problematic, whether because of the sun or increased humidity.
Because not everyone has access to air conditioning, fans are a more cost-effective way to cool a room. Fans keep people cool, not the rooms. But, according to the US Department of Energy, Fans do not lower the temperature within the room.
Instead, fans aid in the evaporation of moisture from the skin. Evaporation distributes heat from your body to the surrounding air, making you feel cooler and, in some situations, eliminating the need for air conditioning.
In our guide, you can learn the best place to put a fan in your room. By the end, you’ll know much more about how to position fans to cool a room with AC, but more important, the ultimate fan placement for optimal air circulation to keep you cool during the summer months.

How Do You Cool a Room With a Fan?
When you want to know where to place fan to cool room, here are some of the best examples. Using these can offer the maximum cooling effect in your living space when the outdoor temperature rises and makes staying indoors unbearable.
1. Push Hot Air Out With Your Fan
One of the most efficient ways to cool a room is to use a fan to push hot air outside and cool air in from another source.
However, blowing hot air out won’t help if there isn’t cool air coming in. The temperature differential between the two sources will significantly impact the method’s effectiveness.
If your room is hot and the weather is cool outside, this method will work to keep your room cooler.
To begin, position the fan at the doorway facing the hallway. Then, open the windows to create a straight air flow path from the windows to the entrance.
When the fan is switched on, it pushes hot air out while sucking in cool air to replace it.
This method can leave some areas of your room with dead spots.
If you have a ceiling fan or a second fan, you can use it to help spread the air more evenly by stirring up the air in the room.
2. Use a Powerful Floor Fan
The density of cold air is higher than that of hot air. This is attributed to the fact that hot air absorbs energy as heat.
The absorbed energy causes the air molecules to expand, lowering the density. For cold air, the opposite is true, and as cold air is closer together, it moves less.
Cool air lurks toward the bottom of your room, and hotter air rises.
To create a cooling effect, you can distribute the cool air. You’ll need tower or floor fans to accomplish this task and circulate the cool air.
Sometimes, a tower fan won’t not enough, and you’ll need an air circulator fan to accomplish the task.
Place your fan on the floor in a cooler area for maximum results. It should be several feet from the wall and away from obstacles. Direct the fan so the air circulation heads toward a nearby wall by pointing the fan upward. As the cool air circulates, the room will be cooler. (Learn How Often To Run Exhaust Fan In Grow Tent)
3. Use a Box Fan in Your Window
A box fan is square and portable so you can place them around your home like a tower fan. However, you can position these in an open window unlike tower fans.
When there is too much heat, you can use your box fan to blow or exhaust air in the room to create a cooling effect. It will depend on the temperature difference between the outdoor air and air inside your home.
If the outside air is cooler, you can quickly create a cool breeze using a portable fan like a box fan.
Box fans drag cool air in by pushing out the warmer air.
Close all your doors and windows in the room except the room you wish to cool. Set your window fans in the opposite room to suck and exhaust hot air outside.
Cool air is drawn in from another room as the box fan expels the warm air, thus improving the air quality with a slight cooling effect.
You can improve your results by using more window fans or oscillating fans to circulate the cooler air from open windows and create a cross breeze.
Should You Point Your Fan Up Or Down?
Here you can learn more about how to circulate air with multiple fans.
Understanding fan positioning is one of the easiest ways to stay cool as the heat rises. Rather than using a powerful fan that blows air toward you, clever positioning can have a more significant effect while being energy efficient.
With any portable fans, rather than point these where you are or down, you can get the best cooling effect by pointing your fan upward when you are in the same room.
Because heat rises, you will be blowing the cooler air up, which then falls and cools the room as it does so.
Ceiling fans can also help with this to cool a room fast. You will, however, need ceiling fans that allow you to reverse the direction the fan circulates.
During the summer, run your ceiling fans counterclockwise. Do this, pushing the cool air down, thus lowering your room air temperature. (Read Tub Valve Height Guide)
Which Way Should I Point My Fan?
Fans do not cool the air, contrary to popular perception. Instead, they blow air over individuals to increase the evaporation rate, create a cooling effect, or circulate it to equal the temperature.
Air conditioning is the most effective way to cool down a room. However, evaporative coolers and portable air conditioners are the ideal air conditioning alternatives because they are expensive to run and install. Even if your AC is on low and use a ceiling fan to disperse cool air, your costs can increase.
Swamp coolers, desert coolers, swamp boxes, and even wet air coolers are all names for evaporative coolers.
They extract heat from hot, dry air by evaporating water. They perform best in dry climates with low humidity. Evaporative coolers are an efficient, cost-effective, and ecologically responsible way to cool down a room.
However, because evaporate coolers rely on fresh airflow to function correctly, you should use them in an open location. You must also refill them with water regularly to function correctly.
Like central air conditioners, portable air conditioners operate on a refrigeration cycle. As a result, they are more portable and effective than evaporative air coolers in hot and humid areas.
The disadvantage is that they use more energy over time than evaporative air conditioners to cool down a room. (Learn How To Balance A Ceiling Fan)
Window air conditioners are likewise energy-efficient and offer many of the same advantages as portable air conditioners.
They can cool rooms while keeping costs low; unfortunately, they are harder to install than portable air conditioners and cannot be easily transported from one room to another.
They are particularly efficient at changing temperature from room to room while keeping your energy bills low.
The disadvantage is that they are more challenging to install and expensive than traditional window and portable air conditioners. With all the above, compared to other solutions, they impact energy bills.
Here’s more on how to keep cool by improving your airflow.
Create a Crosswind
Push out hot air while pulling cooler air in. Next, close your windows, drapes, and blinds to block sunlight. Once the sun sets, open your windows and grab a floor fan and a window fan if you have one.
If you don’t have a window fan, position one fan facing the window, so it’s pushing hot air out.
Use your second fan to create the cross wind blowing toward the first fan. You’ll do this by placing the second fan facing inward from a cooler area or a second window on the shaded side of your home.
One fan pushes air in the opposite direction and into your room, while the other removes warm air.
Use Tall Windows
Place your fan as high as possible, facing out of the window. Because hot air rises, this method helps remove as much hot air as possible and draws the cooler air from a fan low on the floor.
Make a Homemade AC Unit
Place a clean floor fan on the ground as low as possible. In front of this, place a bucket of ice. The fan blasts fresh air from the melting ice to deliver a cool mist.
If you can’t use a bucket of ice, you can place a wet towel or damp cloth across the front of your fan.
Keeping one window open to expel warm air increases the room’s cooling effects.
Angle Your Fans
While it may feel great to close your eyes and allow the fan’s air to hit you in the face, directing the fan directly at you isn’t the best technique to keep cool.
Instead of absorbing the cool air, point your fans upward to create a heat-lifting wind that will keep you cooler for longer.
The air will bounce back and circulate by directing your fan toward the opposite wall, allowing you to restore and maintain comfort with your fan’s cooling power.
A ceiling fan can help push cooler air downward as your floor fan pushes cool air to the ceiling.
