Central A/C doesn't blow cold air

When the A/C turns on, I hear the air blowing. But, it is not as cold as it used to be. When I check the outside compressor unit, I see the fan running continuously. But, I hear something (compressor?) coming on briefly (5-10s) and intermittently.

The unit is close to 4 years old (made by Trane; not sure about the model). Any suggestions on what went wrong would be helpful before I call a contractor.

You can have lots of ifs Ifs here. Compressor capacitor bad Low on freon. Compressor bad . Sounds like it is comeing on and off on the klixon. 4 years old call the the company that put it in . Should have a 5 year warranty on the compressor. Turn it off for sure. You can let the inside fan run

That seems to describe a compressor that is having a hard time starting and is kicking off on overload. Take a picture of the control panel area with the capacitors and post some. If there is a extra capacitor in there (hard start kit) make sure and include those pics. Get a close up of the capacitors top and sides we are looking for any bulging or abnormalities. Probably just a bad capacitor I would replace that first before I did much else.
