You can purchase stationary fans or use ceiling fans in your house. Fans will push around the air in a room and keep it cool. Ceiling fans are often the most effective way to cool down a room, while stationary and tower fans are usually cheaper to purchase. Determine how large you want the fan to be and how it blends in with your existing decor.  If you don't have a lot of space, you could purchase a smaller desk fan. If you need to cool multiple people, you should consider purchasing an oscillating fan. Stationary fans can come in the form of box fans, table fans, and tower fans. You can purchase a stationary fan at most department stores or online. If you place ice cubes or an ice pack in front of a fan, it will create a cool breeze that can significantly cool down a room. This is a great alternative if you don’t have air conditioning. You will have to replace the ice as it melts. Hold your hand in an open window to get the orientation of the wind. Determine which way the wind is naturally blowing and point the fan in the same direction. Position another fan in a different window facing outward, so that it pushes hot air out of the room. This will increase airflow and create a breeze that will cool down the room. Try to remove obstructions in the path of the two windows to improve the airflow. Whether it’s a window unit, central air, or a stationary unit, air conditioning is the easiest way to keep a room cool. Look on the product detail sheet or the packaging of a stationary or window unit to make sure that it’s optimized for the size of the room you want to cool. Then, once you have air conditioning, turn down the thermostat to reduce the temperature of the room.  Air conditioning is the easiest but least energy efficient way to cool a room. Central air is the most effective type of air conditioning. Stationary or mobile units are the least energy efficient types of air conditioning units.
