Where I live, there is no point in having an air conditioner on at night.
In fact, I almost regret buying the window air conditioner that I have in my bedroom since there is no point in using the window air conditioner that is in my bedroom.
I bought the window air conditioner in my bedroom specifically for sleeping. Now, the window air conditioner that I have in my living room is very helpful. That window air conditioner keeps me cool whenever I am at my house during the day. I have a window air conditioner in my bedroom, and the window air conditioner is specifically made to help me sleep. I can usually only sleep with cooler temperatures and loud noises, and I figured that I could find all of that by having a window air conditioner in my room. However, I did not expect that I would be so cold in my room. The window air conditioner literally does nothing at night, because the temperatures outside are far colder than the window air conditioner could make my room. Even during the summer, the night time temperatures reach before 40 degrees. I wake up freezing cold even though the window air conditioner is only on the fan setting. I think that it would have been better just to buy a regular fan so that I could keep my window closed. I do not know what the point of having a window air conditioner in my room was. I should have just saved my money. I only really needed the window air conditioner in the living room.
