The air conditioning is not working. The fan blows, but the air is not cold. I was told by a local mechanic that the system needs to be "recharged." I don't know what that means or if that is a permanent fix.

Recharged: Your air conditioner has a main unit called a compressor. This essentially cools the refrigerant and creates the coldness that your fan blows. The compressor and system as a whole requires a certain pressure (charge) of refrigerant to operate. When low, it cannot operate at all, or operates poorly.
However, the system itself is sealed and should never need "recharged". Unless - there is a leak of some kind. Therefore, if it's low in charge, a diagnostic test should be performed to see where a leak may be occurring...and then ultimately the repair should be performed before restoring the charge in full. This way you are solving the problem, not just putting a band-aid on it.
Hope this info helps!
