How do you prevent AC condensate drain pipe from being clogged?

when season starts, I pour bleach. it works some times but some still gets clogged.

Some say you should use vinegar.

which one do you find more effective. Will vinegar damage PVC pipes?

Never heard of this maintenance procedure. My condensate line is 3/4" copper. Out would probably take a very long time to clog,if ever. I reloaded a nearly 30 year old system, the condensate line was just fine.

The bleach helps deter the mold, a few other things do this as well, pine cleaner works as well and has some oil to prevent drying out.

Vinegar is a weak acid and will not hurt PVC pipes.

I used to tell tenants bleach or white vinegar. AC guy says the white vinegar only as bleach can damage the coils, claims even the fumes so he doesn't recommend it. I've also seen different rules of thumb.

Doesn't seem to make a whole lot of difference though. Some clog, some don't.

AC in our house was installed new when it was build back in 2001. Never have cleaned the line, and the line has never clogged. About 2/3 of our units have central cleaning or clogs there either. YMMV.

I have not had the a coil drain line clog, but I have had a build up of scum at the inlet to the drain line cause an overflow on several occasions. Usually by raising the opposite side of a coil slightly, shim it and of course seal the gap, the water drains faster and eliminates the build up.

I live in Texas also, and this is an annual maintenance issue for us. I know you can put some kind of tablet in the drain pan for algae/mold. We just blow our drain lines out once a year or so (PIA).
