During the summer months it can be difficult to cool down if you don't have air conditioning or don't want to spend money on it. Fortunately, you can easily create a flow of air in your rooms to bring in a breeze and cool yourself down! For simple solutions, try opening a window or creating cross-ventilation, or - for a more permanent solution - making small changes to your room or building so you can stay cool all summer.

Method 1 of 3: Using simple solutions

1. Open the door to quickly increase airflow. If you can, open a door to let out the hot air that is building up in your room and improve the temperature balance in your home.
   • If the room has multiple doors, open them all to improve airflow in the room.
2. Open a window if you want to keep the door closed. If warm air is blowing into the room, opening a window will help draw the airflow out. You can use this method with a closed door as long as air is coming in through the air conditioner.
   • You just need to open the window 2-5 cm open to suck the hot air out of the room!
3. Make sure the air conditioning vent is open if you have an air conditioner. An air conditioner can help create airflow, even if you don't want to set it to "cool". Just make sure the fan is open and then set it to the fan setting so you can circulate the air around the room and cool it down!
4. Using ceiling and box fans to generate circulation. If you don't have air conditioning, purchasing a box or ceiling fan can provide a cost-effective way to circulate air.

Method 2 of 3: Create cross ventilation

1. Install an inward-facing window fan. Ideally, try to place the fan in a window that faces the wind. Install the box so that it faces inward and forces the cooler air into the room.
   • To make your box fan as effective as possible, close the window as much as possible after placing the fan in the window.
2. Place a second window fan on the other side of the room facing out. If possible, place the second fan in a higher window, as warm air rises, and set it to blow the air out. Place it in a window that is not facing the wind. Pull the window down to the top of the fan.
   • This process creates a vacuum, pulls air through the room and cools it.
3. Use reversible fans if the wind in your area often changes direction. Reversible fans give you the option of spinning the fans without the need for heavy lifting, so you can achieve the coolest room possible.
4. Place additional fans in the center of a large room. If the room is large, encourage air movement by placing another fan in the center of the room. The fan should blow towards the outward facing fan to force the air out.

Method 3 of 3: Adjust the room or building

1. Make a small hole of 2-3 cm in the door. A small opening of 2-3 cm in your door can create airflow and cool the room.
   • You can leave the door as it is, or add a grille to make the opening less noticeable.
2. Install a return channel. Return ducts push the air back to the air conditioner so that it can be used again. That allows for more airflow because the cool air entering the room can go somewhere.
   • If you don't already have these at home, they can be expensive to install.
   • A simple way to make air ducts is to make a hole in the floor in the wall cavity. Connect it to the room and the exhaust air with metal plates.
3. Use "jump ducts" to move the air in and out of the room. These are U-shaped tunnels that have the same effect as leaving the door open, as they allow the air to flow out of the room as it enters through the A / C vent. For best results, install "jump ducts" in the attic. To install it, do the following:
   • Make holes in the ceiling plasterboard.
   • Place the "jump-duct" above the chambers, and attach the registers to the channel on the beams.
   • Connect the registers to the plasterboard using "caulk".
   • Fasten the registers to the channel using the approved tapes and metal tape.
   • In the rooms, place a ceiling grid under the duct.
