Where is the drain?

I had the same problem but it wasn't a clogged drain line, it was the gasket between the roof of the camper and the AC unit. The gasket had shrunk and pulled apart allowing rain water in. To make sure you don't have a clogged drain line when using the AC do you notice water dripping off the camper anywhere besides inside? You should have some drips somewhere on the outside.

water draining from condensate hole ??? if not its shut off on high water level (you don't want water dripping into your nice camper right ?)


bees are my nemesis on these they love to build mud nests in the drain holes and stop em up !!

It should drip. That's the humidity from your house. Call them out again to have them verify the drain pipe is clear. Tell them you think they did something wrong. If it doesn't drain right, it will pool inside the unit and cause the internal AC panels to rust if the drain pan (below the condenser) overflows. Or worse, it might be a source for mold to grow inside the system. The later being unlikely, but not impossible.

the inside unit should be mounted with a slight tilt to the outside - so the water can drain outside.
also - be sure your drain hole (in the unit) is not plugged - either with dirt/debris.

It is possible that the drain hole on condensate pan is plugged and causing water to over flow pan. Remove cover from unit and check drain line.Clean coils andpan as best you can and clear drain hole. Add a small amount of bleach to water in drain pan.This will kill any algea or bacteria that may be growing in condensate water and plugging the drain. Thank you

Hello, make sure the unit is tilted toward the outside a bit, if it is level the condensate will collect in the front and start dripping inside the house. Also, if the unit has a drain make sure it is clean so the water can drain out properly.

Check the condensate drain port for blockage and clear the blockage.
If the cover was on upside down, it is possible that it was impeding the air entering the coil.....this could have caused the coil to frost up....during your time to shut the unit off and inspect, the frost/ice started thawing and dripping into your trailer.

Here are the main items you want to address:
1. Ensure the drain is free and clear.
2. Ensure the air filter is clean and properly in place.
3. Ensure the evaporator coil is clean.
4. Ensure the covers are properly in place. ;-)

I hope you find this information to be very helpful to you moving forward. Let me know if you have any questions. Please don't forget to leave a rating for me. :-)

they do that its normal operation, you will get varying amount depending on your location and humidity. If it is not balanced or installed right it drips in the camper.

Remove all covers and look down with them removed and see if the coil drain pan has a stopped up exit where the water drains out and into the rear of the AC unit.

If the unit is off level it could cause a draining problem too.

Does water drip out of unit on the roof while running ? If you look under the unit on the roof, you should see one or two little drains sticking down., that may be plugged up. Piece of wire or something and poke in the holes on the sides of those drains to make sure they're clear. Usually there is a plastic/nylon pan on roof unit to catch that moisture, and drain it off. Could be overflow because of the plugged drains, or I have seen the odd one crack but not too much recently, mostly back 5 yrs ago or so they had a run of them.
