My roommates, despite me explaining it to them several times, do not understand how HVAC works.

One roommate has the top floor and his room is perpetually hot in the summer. His solution to this is to turn his AC down to 58, the “coldest” setting it will go. He thinks it blows colder at 58 than it does at 70. So when he leaves, the AC continues to run day and night. He often stays at his girlfriend’s house.

My other roommate is perpetually cold. She turns her space heater up to 90 because she thinks it blows hotter air.

I’ve explained to both of them that the setting is just where the heater or AC shuts off and that it doesn’t affect the temperature coming out of the device and it falls on deaf ears. Our heating and cooling bills are regularly $400+ a month because of this.

Edit: Just went downstairs and the cold roommate had left her space heater on 89 pointed directly at my couch. All night. I hate it here.

Double edit: I got home and the girl has opened the turned on oven to heat the kitchen up because she was cold. I fucking can’t.
