Probably best to take it to the shop. You've either got a leak and the system is out of or low on refrigerant, or the compressor is shot.

Could also be, but probably not, a failure in the coolant line pressure sensor. If this sensor has failed, or is sending a low pressure signal, the compressor will not kick in.

Uh oh you might have the problem all over again if the lack of fluid was because of a leak.

Air Conditioning Re-Gas

It is recommended that you should recharge your air conditioning system every 2 years with gas and lubricant, in order to keep it running efficiently. This is not included as part of a routine car service and so it can often be overlooked. If your car is more than 2 years old it is more than likely due a re-gas.

This service ensures that your air conditioning system is working efficiently by testing the gas pressure to see if it has dropped. A drop in gas pressure will result in a loss of cooling efficiency which will make your engine work harder and in turn use more fuel.

Due to it's dehumidifying properties, when operating fully efficiently, your air conditioning system will also de-mist your windscreen more rapidly in cold weather.

Yes, you have a leak. Hopefully he put some dye in it to find it with a UV light. They even have leak detectors that can smell where the leak is.
