You will definitely lose all of your Freon when you replace the high pressure switch. Once the high pressure switch is loosen the Freon will begin to access the system.
Any AC, house or car has a pressure switch in the system so that if there is not enough freon in it, the compressor will not come on. The fan will run, but that is all. It is just circulating the air. Nothing will be damaged in the system running it without freon.
