Help! My air conditioning in my apartment is not working?
 

Hello users,

I have a wall unit kind of thing in my studio apartment. It looks like a little furnace against the wall. No thermostat: only high medium and low dial and "Hot" and "Cold". The maintenance man put a lot of gas in it, but it still will not cool the apartment. When I put my hand up against it, sure its cold air, but it smells kind of weird and it doesn't cool the rest of the apartment like it used to. Any suggestions to on what the issue is?

Thank You
Steve Holmes:)

There is mold on the evaporator.
Wait for winter, buy a new one in spring.
