AC condenser drain. How to clean out?

[Vaquero]

Pan under indoor unit is pooling a little.
Overflow drain is dripping outside.
Main drain is dripping too, so it's not completely blocked.

Ideas?

Vinegar or bleach, if that doesn't work run a snake through it.

Air hose!

At work, we have a portable compressed air canister (read re-purposed Freon tank) and an air gun. We blow those lines out and pour a little bleach down them.

Alternatively, use a shop-vac at the far end to suck the slime out of there.

OOOH - this is good - never thought of that.

Air hose for pressure, water hose for pressure (with one of those little shut off valves on the end!) the vacum is a good idea. Snake it from inside or snake it from outside.

If it has enough room for lots of bleach the chlorine will kill off the algae kwick and it shrinks up and goes away as it dies. This action will naturally clear it out....if you have time.

Small squirt bottle of bleach by the filter and treat when you change the filter.

Depending on the bravery/risk factor, I have run the hose pressure IN from the OUTSIDE for just a second then remove quickly and let the surges carryout the crud.

shop vac got it!

 

[Vaquero]

eww!

Pour about a cup of bleach in it once a month.

 

[Charlie]

Somebody send him some toenail clippers, quick!

 

[Vaquero]

That's my new regimen.
Clean drains and clip toenails. Once a month.

 

[Charlie]

Whatever floats yer' boat!

 

[Vaquero]

As long as I've got your permission.

I use an air compressor operated Harbor Freight vacuum pump to pull all the build-up out of the line. PVC cap and clear vinyl line lets me watch what's going on.
I figured that using pressure would blow the line fittings apart up in the attic and then I'd really be screwed.
Glad you've got the problem solved.

Mine overflowed about 3 years ago.
Brought down about 4sqft of sheetrock from the ceiling, lol.

Been mindful every since.

In this house the AC is on a platform inside an AC closet on a tile floor. If there is another house in my future, I again will not put it in the attic.

shop vac got it!

Woot!


I had to do this just the other day so I'm glad it worked for you too.
