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

Placing your fan near the window can help maximize its effectivity. 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.

Keep in mind that a fan's purpose is here not only to circulate the cool air but also to displace the heated air.

In such a situation, an exhaust fan can provide an excellent solution by blowing out the hot air from the room. While the exhaust fans are at work pushing the hot air out, simultaneously, a standard fan should be used to circulate the cooler air.

In conclusion, the key to cooling a room with fans is all about their correct positioning. Adopting these easy and effective techniques can keep your room cooler and allow you to save on energy costs.
