<human>: I live in an apartment that was built above a small warehouse/office. It's an older apartment, but it's big and the rent is really cheap. For the most part I really like it, but it get VERY hot when the A/C is not on. In the winter or any kind of weather 75 degrees F or below it's fine, but now that summer is coming around its getting almost unbearable. It's older so there are only two window A/C units. One in the bedroom and one in the living/kitchen area. When they're on the apartment cools down to around 70-75 degrees F and its fine. At night I don't want to leave them both on, so I just put the one in my bedroom on. It works for the most part, but it's old and REALLY loud. I usually wake up in the middle of the night and have to turn it off it's so loud and then I wake up in the morning burning up. The thing works so I can't really ask my landlord to get a new one.

What can I do do help cool my room down at night?
