A/C dripping water inside

[BeemerBob]

2014 Jayco Octane 26 Toyhauler
Live a Texas and it is very humid here

Of late, we have been having a problem with the A/C dripping condensation on the inside.

I have made sure that I have a clean filter on return air vent. I read somewhere that the drain pan may be plugged, so I climbed up on roof (scary By the way), and removed the cover. I can't find anything that looks like a drain pan or any drains.

Suggestion, guidance needed

I assume you took the top cover off when you were up on the roof. If your unit is a 2014 and the air has been used a fair amount the fins on the air may need to be cleaned. You can do this with a hose without bending them if you are careful. You will have to remove your ceiling cover/filter housing inside and have someone standby with a bucket to catch any water that may come in.

So you are talking about some fins accessible from the inside and not the ones on the outside right ?

I see how to remove the cover for the inside air return but I can't see how to remove the rest of the inside cover.

Sounds like the mounting screws need to be tightened up. There is a gasket between the ac and the roof. From the inside pull the plastic cover off. There will be four screws, one in each corner. Tighten them up. But not to tight. You just want a little compression on the gasket. If you fully compress the gasket, next time, you have to replace the gasket, and that requires removing the ac.

A new gasket is about 1 inch uncompressed, you want it compressed to about 1/2 inch when tightened to prevent leaks of air and water. They also need to be checked at least once a year to ensure they are tight.

So, should I be able to see this gasket from the outside? Would adding some sealant around the unit be a good idea?

You may be able to see the gasket from the outside and or inside with some units and some installations.
The A/C manufacturer's installation instructions do not call for anything but the gasket. There is the possibility that the gasket is bad and may need to be replaced. I have replaced mine on a previous RV years ago and it's not too bad, and the gaskets are cheap.

Ok, thanks for all the advice folks. If it ever stops raining, I'll craw back on the roof, clean the fins and tighten the unit down a tad

So there is not some drain pan that may be plugged?

Many manufacturer's do include a drain pan. Some coaches also have a drain line that snakes down the coach wall and exits under the coach.

I fixed one yesterday for my camping neighbor, it was dripping on the bed. Found one of the four bolts finger tight. Just don't over tighten them when doing this but they should all be about the same torque.

The screws that hold mine are inside and easy to see when the plastic inside cover is removed. The 4 screws on the outer corners should be slightly tight. If one is loose, there is your problem.

We just had this problem in Georgia. The drain is underneath the unit and if you compress the gasket a little too much you plug up the drain holes. Ours compressed enough on its own that it sat on the drain holes and stopped the water from draining. We had a soaked corner of the bed! They had to remove my unit and replace the gasket and now water pours out. You would be amazed at how much water that unit can remove from the air!

Any ac that is not draining water somewhere in a hot and humid climate is not operating correctly.

Some old units had a fan that would sling the condensate water into the condenser coils to help cool them. Now days, I think it just routes it away in a drain to drip outside.

Except in this case.

Next time you get on roof, look on each side of the A/C unit and at the very bottom there is a drain, take a stiff piece of wire and stick it the hole, some stuff may be blocking the hole, once you clean out the hole you should not have any more problems. I have to do that to our A/C about every 2 months to keep the water draining on the roof not in the trailer. The drains are along the side of the A/C.

I had posted a thread which shows the drain holes on the A/C unit.

you don't necessarily have to take the unit this far apart unless it's really clog and the piece you poked out re-clogs the holes. But it will give you the idea where the drain holes are to poke out.
