Reducing electricity costs or keeping cool during the hot season can be achieved by strategically positioning fans in a room.

One key fan positioning strategy involves locating it next to the window. The fan, placed by the window, can pull in and spread the cold air from the outside during the night or early hours of the day.

Additionally, by positioning multiple fans properly, you can create a cross-breeze, making your room cooler.

You should not forget that the function of a fan is not only to distribute cool air around the room but also to drive warm air out of the room.

In such a situation, an exhaust fan can provide an excellent solution by blowing out the hot air from the room. Then, with the help of a regular fan, the cool air can be evenly distributed throughout the room.

To sum up, the secret to effectively cooling here a room with fans largely depends on how they're positioned. By using these simple yet effective techniques, you can keep your spaces cooler while saving on energy costs.
