Condensation in HVAC ducts

Curious since I live in the Deep South humidity capital of the world! I hear what sounds like condensation drips within my overhead AC duct work. Where does this water collect and hopefully drain?

I had this problem with my former TT. I also live in the deep South, S. GA. The A/C was a 13,5000 BTU Dometic unit on a 29 foot TT and for some reason when the weather was hot and humid water would condense on the grill where the return air went in. Never on the cold air output side. The only thing we figured out was that it was humid ambient air within the TT hitting the cold plastic grill and condensing the water from the air. For whatever reason the newer TT has the 15,000 BTU A/C on it and has never done that. The old TT did not have ducted air either but the new TT does.

Typically, there's a drip pan located under the evaporator coil. Moisture in the air condenses in the coil and drips into the pan. The design of the A/C has the pan located a 1/2 to an inch above the roof and behind the opening in the roof. There are usually a couple holes in the drip pan. The water drips out of the holes onto the roof, then across the roof to the gutters, then to the end of the gutters and to the ground.

The best pic I could find is the 2nd pic in post 14 here:

AC unit froze up 8312 SS 2016

The box on the left with the white sticker has the evaporator coil in it; but you can't see the drain holes in the pic.

If you pull off the A/C cover as this guy has, you should be able to see the drip pan and the holes, and make sure they are not plugged or clogged.

Sometimes you can hear the Freon gurgling in the lines. That might be what you're hearing. I don't know if that's normal or means something is going wrong.

Maybe someone with more expertise can chime in.

With one of my SOB campers I had exactly as you describe what sounded like dripping from the A/C overhead duct work.

After many different hours trying to figure it out and pulling things apart, we determined it was noise from expansion/contraction of the duct work and not condensation/water dripping.
