AC unit dripping water inside trailer???

[frankfarmer]

Duo-Therm unit, dripping inside through the air filters. What a pain. Any advice sugestions???? Outside drain is open it drips some as normal. Flooded top of unit on outside, drain line works fine.

Took out filter & looked, coming from somewhere.

Frozen coils? Happened to us a few weeks ago when it was real humid, turned off for a couple of hours and it resolved itself, started cooling again and quit leaking inside trailer

Clogged filters will cause it also!

It starts quick as soon as turned on. Filters are clean. Kinda randon, sometimes leaks, sometimes does not????? Little gremlin no doubt?

My inside leak/drip was caused by loose mounting bolts. Tightened them, added a little sealer and no more leak.

I had the gremlin leak as you described a couple of years ago. After servicing and checking everything to no avail, I was about to just live with a bucket in the bedroom, when all of a sudden it dawned on me...I never leveled the trailer very well. I got out my levels and sure enough it was way off. I leveled the trailer true and the gremlins took a vacation. Give it a try...Hope it works for you too.

Thanks for both suggestions. A building fell on top of AS years back, pushed down AC unit some, bet seal is leaking????, I'll go caulk more & see. Looked at level, it looks OK.

In our previous AS, we had a leak when the unit was running.

It was caused by a crack in the plastic pan where the hose connected.

I was able to repair the pan with a Fiberglas repair kit, and caulked around the hose connection.

I was unable to see the point of the leak until I removed the entire bottom housing.

Good luck!

Do you have a pan underneath? If so it may be in need of replacement.

Removal of AC is ideal to "see" inside.

One thought is to remove top shroud then check for nests, etc. pour water in with a pan or cup to verify water running properly.

You can then use wet/dry vacuum to ensure there are no restrictions slowing the condensate.

Finally, if you can pour in and nothing leaks inside, it may be airFlow restriction.

Finally, I problem "comes and goes" it sounds like it may be tied to the "location" and level of your AS. If you noticed when leaning left or right, fire/aft???

Thanks for your detail advise. Unit is 21 years old, having a new AC installed Thursday, it's past time, also newer unit has a heat pump. Again thank you & all other AS owners for their help.

Duo-Therm Advent 1500 AC unit, works ok but TOO LOUD, try to find some quietier unit before installing one of these loud monsters.
