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?

What's causing the clog?

I'm assuming this is a split unit? I don't have one, but I thought there was a float protection to prevent the AC from running if there was too mich water in it. Of course, this would probably only work if the clog was near the unit itself.

What's causing the clog?

The clog is “gunk” but I’m not sure what is actually causing it.

When I hit it with the shop vac I can hear it clearing a blockage of MISC gunk.

"Gunk" is probably a combination of algae sludge plus any captured lint from the ventilation. Not much to do about the algae other than blast it with a disinfectant like bleach once in a while.

How's the incoming air filtration into the unit? Is it sealed reasonably well at the filter?

Pretty good other than I could probably be a little more diligent with my filter changes. I do it monthly(ish)

Ah yeah, then a little bleach when you do your monthly maintenance will probably help that drain out a lot.
