Ac drip

July 21, 2019, 02:30:48 pm

Went out this weekend for a little getaway and the ac's were working overtime due to it being 95 or so and no trees for relief.. by the afternoon both ac units began a slow drip at the air outlets.. is this an indication that the seal between the roof and ac unit is bad? Or is there something internal that is plugged?  We're not talking a gallon of water but enough to make me wanna put a bowl down to catch it .. I assume these are the original units..

Start by taking the intake panels off. Look up in there to find the bolts that hold it in place. Tighten them up a little bit. Mine was doing the same thing one time, the bolts had loosened to finger tight.

This happened to me. The solution was to replace both ACs out of frustration. Here is what I tried, to no avail:

1. Re-torque the four GASKET bolts. This is the 14x14 standard gasket that comes with all ACs. There is a torque spec, but I forget the number.

2. Cleaned the dual drain channels from the roof. I removed the plastic AC cover and metal baffle to do this, but you may be able to make a tool out of a wire cloths hangar. It needs a small "Q-Tip"-like on the end to clean the gunk.

None of this worked and I got stains on my headliner. The good news is that there was no damage to the roof wood or aluminum.

Now the bad news Tim, what do new compatible units cost?

You have a crowned roof, so you should not have condensate water pooling around the base of your A/C units.

Are you running the A/C on AUTO, or do you have the fan set on HIGH speed?  HIGH speed helps prevent icing.

What kind of A/C units do you have?  They don't look like Penguins.  If they are, there is a possibility my old thread (below) might hold the answer.

But check the easy stuff first.

Keith,

I would not even consider replacement until the problem has been identified.

Could be something as simple as slightly tightening 4 bolts, replacing the roof gasket, cleaning out drip tray, cleaning evaporator and running fan on high .............

Both ac's are doing it.. I'll get up on the roof and pull the covers now that I have identified a few things to check.. I'll have to wait till it cools off a little this evening cause when I go out now I'm leaking more than the air conditioners!!!  thanks all this learning curve is a beeouch!

My units do the same thing, but only if I turn them off.  I like to turn everything off when I switch from shore power to generator.  While off, my units will drip water.  Once I turn them back on, no drip.

I saw AC drip and thought, Man! You need stronger coffee if you are starting to use AC in the arm to wake up.

Fan on high quit our drip when in high humidity.

High fan speed can blow condensate off of the coils, but not likely unless coil surfaces starts to get plugged or part of coil surfaces freezes over. At this point velocity increases rapidly thru unplugged remaining available coil fin surfaces and blows the water off of the fins and past the drain pans. So the problem keeps getting worse and worse.
