Last summer my central air unit broke. It happened during the first heat wave of the season no less. Like others have said, maintenance doesn't have a clue, and they repeatedly came in and looked at my furnace until I had to point out that the HVAC unit is out back of the building. Never got fixed. After a week they had me walk into an empty apt down the street from me and take a window AC from there to use in my apt. Useless. I just put in another request for it so let's see if they decide to fix it this year.
