You can charge by suction pressure only.
Do you have ports on your AC system? When I lost charge on RV AC I had to add tap valve for service.
Did the same with refrigerator.
Read the label carefully what refrigerant it has. Making a mistake here can be a disaster.
Low pressure piping is several times bigger than high side, so it easy to tell.
