Air Conditioning Unit Not Working, What Could Be Wrong?

I purchased a house in December so naturally I did not try the air conditioning unit outside unitl the last couple of days. I do not have a heat pump just a Trane XE 1000 air unit. The thermastat is one that you have to program and I have not been able to do that very well. I noticed the house not cooling down but yet I could hear the furnace running so stupid me thought everything was ok until I noticed that the unit outside was not running. I checked the breakers on the inside of the house and also the breaker outside near the unit but nothing so far is working. Could it be something about not programing the thermastat correctly or is it more likely something wrong with the air conditioner?

What Type Of Air Conditioning System Is This?

I live in an old skyrise building where the air and heat are centrally controlled in the building. I have a rectangular box sitting in my condo that controls the air flow but not the temperature.
So basically, I can cut the AC or heat off and on, which ever is running at th time in the whole building.
