AC condensation on the interior

We have a 1975 Soverign. When AC is running it is dripping alot from the vent in the cieling. The AC works well but we have to put a bucket on the floor as it drips constantly. Where should we start? This is our first airstream, and our first travel trailer. We are Rookies.

You may have a condensate drain line plugged.

The first question is does it have its original AC, or a newer model? It should be obvious by having a look at the way the unit attaches to the shell. An original unit will look like it has been screwed or pop-riveted to the shell all around the perimeter of the unit. A newer unit will look like it is just sitting on the roof, and it is held in place with screws that clamp it through the main hole.

If it is an original unit, then you might have a plugged condensate drain tube. remove the inner ceiling unit, and you should be able to look up into the hole in the ceiling and see where the drain tube connects. Troubleshoot the blockage with a plumbing snake or compressed air.

If you have a newer unit, you still might have a blocked drain tube, but there is typically a plastic pan that the unit sits down into, that is meant to catch the condensate. These pans get brittle and crack, and you might be getting liquid coming from a break in the pan. Again, you will have to remove the ceiling unit in order to see where the connection is made.

Good luck!

First off, welcome to the Forums. We're glad to have you with us.

We have a similar situation with our air conditioner. It sometimes drips water on the floor. We have found that when our unit does this, the filters are pretty clogged with dust. We clean the filters, and the dripping stops. The dripping water has become our signal the the air conditioning filters need cleaning.
