water from A/C; normal or leak

Great sunny sunday, yesterday and I decide to run on the A/C...
So water began to fall from it on my new red floor, drop by drop to stop after 5/ 10 minutes;
is it normal or there some leaks in the A/C system ?
Each time I'dl run it,should some water fall down ?

thank you

Not Normal

Bruno,

You have one of two things happening. You have a leak in the drain pan or associated tubing, or there is something blocking the drain and it is overflowing into the trailer.

Both of these assumptions are if you have a factory (Armstrong) Ac installed. Aftermarket is a whole diffrent issue.

To check:

Pull the inside shroud, 4 screws, 1 or 2 knobs. You should be able to see the drain tube on the right side (facing the rear of the coach). This tube connects to the pan. With the inside shroud off you can run the unit to see exactly where the leak is coming from. Be careful to keep fingers away from the fan, or you could end up missing a few of them.

water from A/C; normal or leak

Greetings Bruno!

An interior water leak from your air conditioner is not normal and indicates that there is a problem. I would suspect one of the following:

1.) If your coach has the original Armstrong Bay Breeze air conditioner, I would suspect that one of the drain lines from the condesate pan is plugged. The most typical solution to this problem that I have heard proposed is using low-pressure compressed air to clear the clog from the tube(s).

2.) Another issue might be a sealing problem with the drain pan itself at the attaching rivets or around the roof penetrations.

3.) If your coach has a replacement air conditioner, I would suspect a sealing issue.
A.) Based upon the installation of a new unit on my Overlander, I would consider a possible culprit being a lack of bracing between the interior and exterior skins in the opening that had to be cut for the new air conditioner - - treated wood blocking was installed between the interior and exterior skin on my coach to prevent the skins from being crushed by the mounting hardware for the new air conditioner - - if these skins are compressed, it would form a well that the condesate could drain to and leak into the coach.
B.) This may have been necessary only with the replacement Coleman air conditioner on my coach, but the dealer also added two supports on the exterior between one of the roof bows and the air conditioner unit to lessen the possibility that the air conditioner might move and distort the opening cut in the roof.

Good luck in locating the source of your condesate leak!

Kevin

Pull the inner shroud off and check the connection between rubber hose and the drain pan. My brand new trailer had a leak at this connection. I would get a drop falling inside the trailer about every 10 seconds.

Our new one had a leak there. I used low pressure air to make sure the tube was clear, and it was. Turned out the hose leaking around the pan attachment (the clamp was all rusted) and the big glob of sealant spread all over where the hose and the pan joined wasn't sticking to the pan.

Exactly the condition of mine except that the clamp hadn't rusted yet. A big gob of white sealant encased the clamp and the outlet of the pan, but had not bonded to it at all. I was able to peel it off with my fingers.

Yep... that's what the Airstream service center tech told me... peeled it right off with his fingers. He roughed it up with sandpaper and used a cleaner before reapplying the sealant.

drain tube leak

Again on this thread because today was a very warm day and I 've decided to turn my A/C at his maximum; Waouw great fresh air ...
After spent a few time inside to prepar my holidays ( 26th july.....)I stop the A/C and... it was raining in the airstream...from the A/C.

I discover the drain tube water was not well mounted and his support was broken....

Now I know; I prefer that instead of a leak on the roof.

Bruno;
