check your R134a levels, you can get a can with a gauge on it for like $20. If you are a little low on freon your compressor could cycle more, it could also need more oil. Of course if you are low, then that means there is a leak, but usually the can stuff will have some leak finder and sealer in it.
I was thinking when I read the thread title it was going to be the Water Pump, it makes a noise when it is bad, but you are describing the compressor.

My A/C does not get cold so I know I'm low on freon but how well do those cans work? Is it better to have the system drained completely somewhere and re-filled? I know they have machines for just that.
