<prompt> Human: Hello me and my girlfriend are staying in a one bedroom one bath apartment in Orlando fl. It has one loft as well upstairs. We are rarely home and hardly have any lights on most of the time.. We keep the ac on at night on 70 degrees Fahrenheit and 76 degrees during the day when we are home. We tried turning it off when we werent home but got the same results. We pay anywhere from 180-220 every month. We called our electric company which is called OUC to find out whats going on and they say we have to pay 40 every month for waste management which is every time water goes down the drain. So we basically pay 140-180 on just electricity . Is this normal? Our apartment is 990 sq feet. Any help would be great. Thank you.  <response>: We keep the ac on at night on 70 degrees Fahrenheit and 76 degrees during the day when we are home.There is your answer. AC is expensive.
