To those wondering if it's "not as cold as it should be", get a thermometer (preferably one with some sort of probe) and place it over an air vent, and turn the air and AC on. If you've got climate control, set it to "low" or whatever, not just 16c or something. If the air coming out is less than about 7-8c then you're fine. It's normally 3-5 IIRC.
