Air Conditioner Drain hoses clogged?

[jbchevy3]

2 of my 3 air conditioners drain down the side of the coach instead of through the drain lines. Does anyone know the proper procedure for cleaning them out and where are they located? Are they visible once you remove the covers on top of the a/c units?

I guess mine has no drain hoses as the water runs down the roof and out the rain gutters. Every unit I've had did the same thing maybe I'm missing something. Jim

I had two airstream motorhomes that had drain pans under the roof airs. The drain hoses on both were routed through the walls and came out at the bottom of the wall directly under the AC's. Dirt daubers kept stopping them up and I had to put screen wire over the ends to prevent this from happening. It was a simple procedure to clean them out with a straightened out clothes hanger.

Good Idea on the screen wire, I'll locate the drain hoses. I understand that Country Coach has drain hoses on 06 and later products.

thanks

My AC drains are near the front driver side wheel well and I think near the rear passenger side wheel well.

Since my rig is 11 years older and has no slides, it is likely that the locations are different on your rig. You might try some compressed air down the hose from the top to dislodge the blockage as it would appear that my hoses make a 90 degree turn somewhere.

Compressed air down the condensate drains will generally clear them. These are prone to clogging due to algae buildup; algaecide tablets are available at A/C supply stores, and keeping them in the condensate pan will prevent algae buildup. A periodic shot of chlorine bleach works pretty well as well.

I would NOT use compressed air to blow out the line. You could blow a fitting off in the wall and wind up with the AC water emptying into your wall.

Definitely would not want that to happen.

Jerry,
Did you resolve this issue?
If not, we had the same issue and discovered that our condensation went into a recepticle adjacent to the A/C unit and then is pumped out by an electric pump into the condensation hoses that then go overboard. We were leaking onto the roof because the pump was dead and the receptacle holding the condensation was overflowing onto the roof (and sneaking into the ceiling of the coach, too). Does your coach have the condensation receptacles and pumps as well?

Mine does have the pumps too. I think the pumps are bad as well. Plan on fixing them this week. No leaks on the ceiling (that I can see) at this point.

Jerry-
i would suspect the pumps too. After I replaced the pump, i checked continuity of drain hoses and found the front one had a bad splice that leaked too. It ran through roof and into passenger side windshield post, ending just above bottom of front end-cap. If you need more info on pumps I'll be glad to look it up and PM you with model #, distributor, etc. Let me know...

Mike,
I had the pumps checked, and blew out the drain lines, they were all working. But what I did find is the drain pan on the front air unit was cut for some reason allowing water to run out. Ordered a new one for $15. Patched the cut one until it comes in.

Jerry- sounds like the problem is solved.
Not to worry, though-
I'm sure there's another one lurking around the corner...
