For a sealed system, the process involves desoldering the service port, connecting a manifold to the service port and pulling a vacuum (capturing the old refrigerant for disposal at the same time), recharging the system with new refrigerant and soldering the service port closed.
Or you could just use piercing service valves on the high and low sides. If just charging, no need to pump down, but if it all leaked out, well, find the leak, repair, replace dryer, pump down, recharge, test.
$800 sounds like a compressor or evaporator replacement was also quoted.
