Heating and Cooling Hell

So, what started out as a fairly normal day has rapidly descended in to Hell. The HVAC guy came out to my place of employment to "change our filters." He decided to clean something with a particularly noxious solvent, so people were fleeing the building to get away from it. We were told it was fine, it would go away, open a couple of windows and quit bothering them. (Point of interest - this building has floor to ceiling windows, but not a single one opens. The front door is the best we can do.) About half an hour later, there is a burning smell coming from the vents. After calling the HVAC people, we were told it was fine, it would go away, open a couple of windows and quit bothering them. Once the smells were finally gone, we closed the front door and quickly noticed that it was 87 degrees in here. There is no air conditioning. We call the HVAC bag of hammers again, and I guess he meant it when he wanted us to leave him alone, because it's been FIVE HOURS with no sign of him. Does this sound like someone trying to create job security for himself? Everything was fine before he came out. We didn't call him. He just showed up! Did he maybe break it to make more money from us? Is it a conspiracy? This happens with our copier repair guy all the time. Well, after he shows up this time (if he shows up), we'll be choosing a different HVAC idiot randomly from the phone book for NEXT time. In the meantime, my normally sweet and sunny disposition has been replaced by a sweaty, snarling, frizzy haired monster. K has been trying to enlighten me with some realization techniques, so here goes - "I am the possibility of freaking out at any provocation."
