Leaking ac

rhe ac unit is not original to the airstream, water steadily drips down through the filter area while running. When it rains the water pours through in the same areas. The ac unit was installed by an RV company? What do I look for, where do I start in fixing this problem?

Make sure they hooked up the drain line. My AC was replaced by Airstream at the factory and they did not install the drain cups or hook up the drain line.


Do you know what a learning experience is? A learning experience is one of those things that says "You know that thing that you just did? Don't do that."

If it is a non-standard AC installation it might be tough for folks here to provide helpful comment,

But if it drips when it is NOT raining and drips much worse when it is raining, it sounds as though you could have two issues,

(1) AC design is usually such that normal condensate created on the evaporator from the AC operation is normally routed to a drip tray that has a connecting pipe running in the wall to drip out into the trailer wheel well outside the trailer - you should likely see a rubber tube hanging in the wheel well to let this water escape onto teh ground.

Possibly the drain line can be blocked and if so you might be able to clear it by gently blowing compressed air up into the drain pipe.

(2) If you get a lot of water coming in when it rains then you may have trouble with the foam sealing gasket used to seal the AC unit onto the roof. The gasket alone should provide all the seal you need against rain water entry - normally there should not be any caulking material.

I don't know your design, but in ours there are three or four bolts (forget which!) accessible from inside the trailer when you remove the inside AC grille, and it if so, slightly tightening these bolts to compress the gasket more might help.

Hope that is of some help.

Pull the filter out. Look into the hole on the drivers side and see if a connection was made to the original Airstream drain. I suspect it was not and they made some makeshift drain directly to the roof.

You may be able to buy the drain kit designed for AC units to be installed on an Airstream. That will require removing the AC to install the kit and reconnecting the Airstream drain.

The picture shows one of the drain cups, the tubing connecting them, the connection to the Airstream drain, and the additional gasket to raise the unit.
