i think i know why the a/c is broken.
it probably has something to do with all that ice and condensation on the side of the chiller, around the coolant intake pipe. unfortunately i only discovered the ice and condensation after it was well into becoming water, and soaked through the cardboard box of laundry detergent i keep tucked away in the little space between the door and the chiller. well, i asked the building to have maintenance stop by tomorrow to check it out. i guess that’s good timing. or something.
