Vinegar vs bleach

With AC’s running full tilt this August in Central Texas, there’s the vinegar vs bleach debate for keeping AC condensation drainage lines open. The HVAC guys who installed our Lennox said to use a cup of bleach every month. Guys in Neely’s Canyon say on our email forum they prefer vinegar. Bleach is said to wear down PVC tubing faster.

I already used bleach for this month. So, preferring not to add acid to a base (and get a very mini but potentially unpleasant Beirut effect), I’ll wait until bleach time next month to switch to vinegar.
