2005 Ford Escape Question: Is it my compressor?

When you turn the vehicle on it start to make this knocking/rattling noise. It was only happening every now and then and when parked. But in the last few day it has gotten to where as soon as you turn the truck on it starts. Someone told me it was the compressor, but I'm not sure. -
