Bleach *may* have an effect on the PVC and connections. Fumes from the vinegar or other acid *may* come back up the line and affect the aluminum condenser. It is probably debatable how significant either of those two concerns are but it's hard to imagine they would be recommended at all if they were high risk.
We use a gallon of hot tap water every month. No fumes and no mixing/measuring/dilution required. The volume *might* be enough to flush the lines and the temperature *might* be enough to kill any algae. If the gallon begins to back up then I know I have a problem starting and can take other measures to clean it out (nothing so far). I don't have nine years with this technique yet but so far so good.
