There is a real tendency to think when it gets hotter, you absolutely have to get an air conditioner. If you are living in an apartment and there is no central AC, you would have to spend a lot of money on an air conditioner. Another issue is that you will have to deal with higher energy bills.
The good news is that you can make do with a fan if you are smart about it. Provided it does not go beyond the high 80s F where you live, you can get a Ceiling fan and be done with it. These fans are great for keeping you cool.
The reason why we recommend you go with a fan on the ceiling is because it circulates cooler air throughout the room. It is not only about keeping the space cool for one person, but anyone in the room would notice it is a lot cooler with the fan.
You will find it a lot easier to get to sleep when there is a ceiling fan. Even on its lower setting, a gentle breeze is going to make you feel great on the hotter evenings.
The fan on the ceiling on its own may not be enough, which is why you should open up your window when it is night time. The temperature will likely be in the 70s or lower, which will allow the temperature in your room to start coming down as well.
A combination of the cool air from the outside and your fan will make you feel great. If you want to go a step further, you can also get a box fan for your window, which will blow in the cool air from outside at an even higher rate. Then you will feel so comfortable all summer.
