Too much heat and humidity will make the room stuffy and uncomfortable. If you have an air conditioning system, just turn it on and wait for the room to cool down. However, not everyone has an air conditioner, and it will be very expensive for you to keep it on throughout the summer. Fortunately, here are a few tips to help you cool your room without the need for an air conditioning system.
Steps
Reduce heat source

Close curtains/curtains. About 30% of unwanted heat comes from windows. Cover the windows to prevent direct sunlight from entering and heating the room. Buy curtains or curtains if you don’t have one in the room, especially for west-facing windows. When the window is covered, the temperature in the room can drop significantly. [1] X Research Source
- Try to cover windows from morning to evening during the hottest days.
- If you often have to deal with high temperatures in the room, you should buy insulating curtains.

Turn off unnecessary lights, electrical appliances, and heat-generating devices. Any active appliances contribute to heating the room, so it’s a good idea to turn off everything that’s not in use. Computers and televisions are heat-generating devices. Incandescent bulbs are also a great source of heat. If possible, you should turn off all the lights in the room.
- It’s not always possible to turn off all the lights, but you should at least keep the light as low as possible. [2] X Research Source
- Consider replacing incandescent bulbs with miniature fluorescent lamps (CFLs), or better yet, light-emitting diodes (LEDs). CFLs and LEDs produce much less heat, [3] X Sources of further research are environmentally friendly.

Clean up clutter. Piles of clothes and other clutter will absorb and trap heat in the room. The less furniture a room has, the more space it has for heat to disperse and cool down faster. [4] X Research Sources High piles of furniture also block the flow of air, making the room appear hotter. Put all your clothes in the closet and close the door.
- Scan the room for clutter and clean up quickly if possible.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e6/Cop-Down-a-Room-Step-4.jpg/v4-728px-Cop-Down-a-Room- Step-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e6/Cop-Down-a-Room-Step-4.jpg/v4-728px-Cop- Down-a-Room-Step-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Open windows in the room and close all other rooms in the house. If it’s hotter indoors than outdoors, it’s likely that the walls have absorbed a lot of heat from the sun throughout the day. You can expel the hot air in the room by opening the window. [5] X Research Source You should also close any unused rooms in your home to cool the room you’re in faster. [6] X Research Sources
- Remember to close the window when the room is a bit cooler.
Air circulation
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e0/Cop-Down-a-Room-Step-5.jpg/v4-728px-Cop-Down-a-Room- Step-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e0/Cop-Down-a-Room-Step-5.jpg/v4-728px-Cop- Down-a-Room-Step-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Turn on the ceiling fan and adjust the fan mode. Ceiling fans are very effective in helping air circulate in the room and create airflow. [7] X Trusted Source US Department of Energy Going to the source Air will also be lifted in circulation thanks to a ceiling fan, and since hot air always rises, your room will cool faster. [8] X Research Source If the ceiling fan is not on, turn it on. If the ceiling fan is running slowly, you need to set it to the highest setting.
- Check the propellers to run counterclockwise (when viewed from the bottom) – if not, you need to reinstall.
- Adjusting the fan blades to rotate counter-clockwise and turning the fan on to the highest setting will help increase air circulation. [9] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8e/Cop-Down-a-Room-Step-6.jpg/v4-728px-Cop-Down-a-Room- Step-6.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8e/Cop-Down-a-Room-Step-6.jpg/v4-728px-Cop- Down-a-Room-Step-6.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Turn on any other fans you have. Table fans, box fans, swing fans and wall fans also help to circulate air in the room and create a cool wind effect. [10] X Trusted Source US Department of Energy Go to the source A rotating desk fan will quickly and effectively dispel stagnant hot air. You should leave multiple fans in the room during the summer so that you can turn on the fan as soon as you enter the room. [11] X Research Source
- Turn on the exhaust fan in the bathroom. The exhaust fan also helps draw hot air out, similar to when you take a hot shower. [12] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/5a/Cop-Down-a-Room-Step-7.jpg/v4-728px-Cop-Down-a-Room- Step-7.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5a/Cop-Down-a-Room-Step-7.jpg/v4-728px-Cop- Down-a-Room-Step-7.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Place an ice tray in front of the fan. Transform your fan into an “air conditioner” by placing an ice tray, bowl, or pan in front of the fan. This will create a cool, misty air flow in the room very quickly. [13] X Research Source You can also use an ice pack, or if you don’t have ice, improvise with something equally cold, such as a bag of frozen vegetables.
- Place the ice bowl slightly tilted up if the wind from the fan does not seem to be blowing over the stone bowl. [14] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/67/Cop-Down-a-Room-Step-8.jpg/v4-728px-Cop-Down-a-Room- Step-8.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/67/Cop-Down-a-Room-Step-8.jpg/v4-728px-Cop- Down-a-Room-Step-8.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Place the box fan at an open window and facing out. The fan will pull the hot air out and circulate the cool outside air into the room. Place the fan in the window that gets the most shade – that way you’ll get more cool air in. Close all other nearby windows and open a few in the opposite direction to circulate air throughout the house and cool it quickly. [15] X Trusted Source US Department of Energy Go to source

Install a window air conditioner or a portable air conditioner. [16] X Research Source One of the most effective ways to quickly cool a room is to install a window air conditioner. This type of machine has the effect of cooling the air in only one room. [17] X Research Source The central air conditioning system will have to cool the entire house, and that will take more time. Installing a window air conditioner is also easy, especially for sliding windows.
- If you do not want to install an air conditioner or your window is not suitable for installation, you should consider buying a portable unit. This type of machine requires no installation – you just need to plug it in and turn it on. [18] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e7/Cop-Down-a-Room-Step-10.jpg/v4-728px-Cop-Down-a-Room- Step-10.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e7/Cop-Down-a-Room-Step-10.jpg/v4-728px-Cop- Down-a-Room-Step-10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Open windows at night. [19] X Research Source Nighttime temperatures are often low, even in summer. Take advantage of cooler air at night by opening a few windows before you go to bed. Place a fan or two across from the window to create cool convection. Close the windows tightly in the morning to prevent hot air from entering the house, remember to draw curtains to cover the windows. [20] X Research Source
- You should also unplug all electronic devices in the room at night to further reduce the temperature. [21] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f6/Cop-Down-a-Room-Step-11.jpg/v4-728px-Cop-Down-a-Room- Step-11.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f6/Cop-Down-a-Room-Step-11.jpg/v4-728px-Cop- Down-a-Room-Step-11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Consider buying a dehumidifier if you live in a humid climate. Humidity can make the air even more stuffy. If you live in an area with high humidity, you should buy a dehumidifier. This device sucks the humid air in the room and passes it through a special coil before pushing it out again. You can buy a dehumidifier at electronics stores.
- Dehumidifiers aren’t cheap, but they’re portable, so you can take them from room to room to maximize efficiency.
- For best results, place the dehumidifier in the center of the room you’re trying to cool. [22] X Research Source

Choose the right curtains. If using curtains, you should choose a neutral color with white plastic material on the back to prevent heat more effectively. Hang as close to the window as possible. Curtains are also very effective at insulating heat – be sure to fit them very close to the window glass to create a sealed space that is insulated from the heat. Consider buying blinds that have two sides, one light side and the other dark side.
- In the summer, you can install the light side facing out to reflect the sunlight; In winter, keep the dark side facing out to absorb heat. [23] X Trusted Source Consumer Reports Go to Source
