My AC drain gets clogged every so often. Any trips for a more permanent fix? (lemmy.world)

About 2-3 years ago the line clogged and I didn’t catch it for a while and we had some serious water damage. It just clogged again and I caught it pretty quick but it could have been bad.

Shop vac solves the immediate problem but I’d like a more permanent solution. Any ideas?

I live in Florida, I keep two things on hand for my HVAC drain line. First is condensate cleaner (less harmful to the plastic than bleach) which I use monthly and my backup is a Gallo Drain Gun. Even on my worst blockages, 2 shots of the drain gun cleared it out.

    Do you have a brand or version (looks like there is liquid and tablet) you’d recommend? I think it’s a good idea to start with this monthly.

    I had a blockage that left puddles in my basement when were running the ac a lot during July. A couple of the blue ac safe tablets took care of it.

    Can't say I've seen much difference, In my case, there is a place inline in the drain tube to pour in liquid so I use Algaecide in that but if you don't, use the drain pan tablets -- no idea which would work better though. It does work best as a preventative before you get buildup. My drain line is long with many twists and turns, lots of places ideal for buildup (I curse the builder for this!)
