So my AC is now cooling after the thermostat reset procedure I got from the service guys at Colonial Airstream. Yay!

It is cooling so well, in fact, that in the hot, humid Florida days, the condensation is so much that it is leaking into the cabin.

Sigh.

I had a Dometic authorized tech come out and he said that the AC units were too "low" in the roof and there were some plastic tabs that were blocking the drain holes. He proposed removing the tabs, which requires the removal of the AC units. $250.

Double sigh.

I've read a TON of threads on internal leaking from condensation. My units are draining through a small pipe over the wheel well, but apparently not enough. Running the ACs on high fan alleviates the problem, but proper drainage seems to me to be the correct fix. So I am going to accept the tech's proposal.

Thoughts?

Could you give me a phone number or email address of the person that gave you all the information for the reset. Thanks.

Before you do that take a small diameter wire and clean the drain hose up from the wheel well.

It was the service guy at Colonial Airstream. And the procedure is outlined in the AC manual.

Please give us the details when the tech does his thing. I guess I have a hard time visualizing what he means by "mounted too low," and the plastic tabs he is referring to are equally puzzling. It sounds like the condensate is making it out of the AC unit and into the condensate drip pan--hard to understand why there would be tabs keeping the drip pan from draining into the condensate tube, when that is exactly what it is designed for.

These are factory installed units, right?

good luck!

Yes, factory installed. We think the problem was too much condensate for the drain tubes to drain properly. He drilled holes in the drain pan to drain onto the roof. That fixed that problem. I still have some minor leakage when I turn the fans off after running all night. Apparently the fan is creating a vacuum and holding onto some water that drains when the fans turn off. Thankfully it's just a few drops.
