Why would you want to flush your A/C system? 
Refrigerent doesn't go bad and it's a sealed system.
You can have your system evacuated with an A/C machine then pull a vacuum for 20 minutes, that pretty much empties it totally. Next charge it with the correct amount of R134. That would give you a fresh start with a system charged correctly. Your own refrigerent would be reused and a slight bit of compressor oil can be added as well to make sure the compressor is properly lubracated.
