Turn the AC on!

Is it just me or is it hot af on campus? Im like genuinely uncomfortable here in NatSci!

Edit: I know that the AC system in buildings don’t turn on and off like a car but thank you all for educating me I was not expecting to learn this much on AC loops. To provide some context I work in a lab with lots of glass with no ventilation and was just venting (no pun intended lol).
