Are you sure the system is low? If the A/C just recently quit working check the low pressure switch on the accumulator. Jump the connector using a small paper clip and if the A/C starts blowing cold replace the pressure switch. No need to drain the system for that. Just unscrew and screw the new one in. Let me know what you find or if this helped you out.
