A small amount of water is dripping from AC vent. Seems to be normal drip on out side.
I have not had this problem in the past. Thank You.

All good suggestions, but also consider that if hot moist air comes in contact with the cold AC vanes there could be condensation that forms.

That is why there is a pan with drain holes that ksg mentioned. It is to carry the moisture to the outside. All air conditioners do this.


You're missing my point. Not talking about condensate drainage. Cold fins, moist air = drip, drip!


I got your point but stand by mine. The pan will catch all that drip, drip and direct it outside. The OP stated that he found the drain plugged.


Again! The OP is talking about the air outlets not the evaporator. When the outlet fins get cold condensate forms and drips. There is no catch pan for that...

Mine wasn't cooling that well for Texas in July, so I added a portable AC that I vented out the back window. Between that and camping in partial shade this weekend, it stayed really cool (no higher that 73 or 74 during the day and in the 60's at night). The problem is the gulf coast has high humidity, so in addition to the normal dripping from the roof of the trailer, I saw condensation dripping from many of the vents and even a couple of the light casings. It seems the plastic around the vents got really cold and the high humidity caused it to condensate to water. Even one of the light housings, which are plastic, had some cold air blowing on it and a few drops condensated there.

Thank you all for the good advice. I was a drainage problem, but because both units are taken apart
and cleaned annually, I just expected some other than a plugged drain. Thanks again guys!!

If it is dripping from one of the cold air vents, it is probably condensation on the inside.

Happens all the time on mine, especially in the bathroom when showering. Moist air hits the cold air coming out the vent, and condenses into a drip.

True.......

But in high humidity the condensation can overwhelm the evap coil drip pan drain holes cause they are usually small holes.

When in humid areas we would get a little carry over on occasion. Steady stream running off roof. I'd go up on roof remove shroud, remove evap coil cover and find the drip pan full and both drain holes free/clear running water.
So I made the holes bigger........no more carry over.

Sometimes you have to 're-engineer' OEM stuff for it to work correctly in the real world.
Is it time for your medication or mine?

If AC drips when raining - try tightening the 4 bolts. If AC only drips when running then chances are the drain holes in the pan which collects condensation from the evaporator coil have plugged up - need to clean them out.

That Cajun heat may have cooked your air conditioner gasket although your 5er seems too young for that to happen. Get on the roof, pull the cover and look for blockages.
