You can pull the heat out of the air quickly. But 80% of the heat remains in the walls, mattress, desk, slab, whatever

The room may be 20C, but I guarantee you if you put a turkey thermometer checker into your mattress it's going to be 27C

assuming unit is prolly sized

Yea, our biggest thing is the insulation is pretty much non-existent but I think you’re still right in that maintaining will be less work/less time than trying to pull down an already hot room at 6-7pm
