I noticed my office was getting a little cold, and the thermostat didn't seem to have any say about the actual temperature in the room, so I did a little investigating and found that the hot water lines to the air heater boxes were shut off. Not wanting to just turn the valves open again (maybe they're off for a reason, maybe because of the corrosion around the drain valves), I mentioned it to maintenance.
A couple months later they started a $21 million refit project of the building's heating and air system. When they came 'round to my room I figured, "Finally, I'll have some heat." They came, they went, and now I have two bundles green wires sticking out of the wall where the thermostat used to be.
So now, even if I were to open up the water lines, I'd still have no heat, since the vacuum lines were disconnected, and the control valve is stuck in place. And there's still air flowing through the ducts. Nice, unheated outdoor air, which I can't shut off. So the system is not only not heating the room, but it's actually cooling it.
But at least I have a window. A nice large, barely insulated window. Go November.
