Rainwater Leak At A/c

[CACTUS]

Water leak at what appears to be a water drain at left side of a/c. could this be clogged. I do not want to disconnect it till I know what it is.

I also have a water leak at the A/C. The drain line on the left side is for draining condensation from the A/C while it is in use. I suspect my leak is cause by a bad A/C gasket. Sometimes you can stop a leak at the gasket by snugging up the four A/C bolts. In my case this did not help the situation.

There are really two options.. It may be impossible to test A/C in winter in cool climate, but general rule is rain leak means bad "gasket seal", which is ~14" square sponge rubber that fits around hole in roof, and gets hard and fails after some years of heat and sun. Find qualified shop to unbolt, lift and replace and leak should stop (ours did last summer, after we discovered problem during severe thunderstorms on trip to Wisconsin..)

If it also drips inside on hot humid days, it could be drain or could also still be seal. I'd fix seal first, have tech check drain fitting and hose for obvious clogs, and hope problem is solved..

Cactus, when this occurred on my trailer, I lay down beside the trailer on the driver's side where the drain tube emerges, and blew hard up the tube. After two sharp short blows I had to dive hard left to avoid a jet of dirty water rushing down the tube. It had been blocked by dirt and mildew. You might ask a friend to show you how this is done, while you watch admiringly! The AC sits in a tray,and this is drained by the tube. If the tube blocks, the tray eventually overflows into the trailer. By removing the internal AC cover, I also found a crack in the corner of the tray. I sealed this with a large glob of Vulkem. No more drips on the carpet. Good luck with your search. Nick.

Southeastern VA is famous for growing black mold everywhere. Air conditioning drain valves always clog up with disgusting gunk. The first time we turn on our business air conditioners every year, we take our shop vac, hold the hose to the drain valve and suck away. Almost always get a big clog followed by a lot of water and problem solved for a year. (Did I just pass on a chance to make a naughty joke about technique?)

I'd rather have the vacuum get soaked than catch a faceful of what comes out!

I had the wet carpet too from the condensate line.

I solved this by using a plastic weld on the connections from the pan to the hose. I also had a crack in the pan which I sealed as well. No problems after that.

BTW, I did not have a backlog of water in the pan showing a clogged up hose, but know this is a problem as well.
