noisy freon lines

I had central air installed in my home 4 years ago, the lines run up the wall at the end of the house to the attic, where they cross over my living room to the air handler, since the unit was installed when it starts up and is running I hear the freon running thru the line from my living room below sounds sort of like sucking soda thru a straw, could there be air in the system? maybe it was not evacuated properly before inital charge?

Post brand, size of unit and the size of copper lines. Doubt it is air.
