A/C condensation water that drips from the bottom of the truck is normal. Living in AZ the A/C is on all the time, and I'm used to the small amount under the truck. But for the past 2 days I have seen large puddles under the truck. I know its water, but the amount is concerning me. It only happens in the morning after I've driven about 15+ minutes, and reverse into my parking spot at work. I can see it coming from somewhere over the transmission, then leaks down the housing, and off the pan as well. This doesn't seen like a normal amount, and I'm concerned that something has been knocked loose, or broken involving the A/C system. Thanks in advance for any help! leak1.PNG

If there's no anti-freeze in it there is nothing to worry about. Take a piece of cardboard with you and throw it under the truck when you get to work. You should be able to tell whether it is just water or coolant by looking a what is on the cardboard.

This is perfectly normal and not usual for our routinely dry air here in the Valley of the Sun. Usually we have triple digit temps with single digit humidity. During the hot dry days the A/C will still condensate a little bit but not enough to make the ground wet under the truck because it normally evaporates as soon as it drips on the hot pavement. The past two days, however, have also been unusually wet with the recent monsoon storms that blew through. All of my vehicles are condensating more water with the A/C systems running.

Just another note: because you live in AZ, after the monsoon season has passed us consider replacing your cabin air filter as the filter that is in there now will certainly be loaded up with the dust and debris from the monsoons. Additionally, with the increase in moisture content in the air and increase in condensate from my vehicle's evaporator core I make it a practice to turn off the A/C compressor and shift to fresh air with the A/C fan still on when I turn into my neighborhood and I let it run until it starts feeling decidedly warm blowing out of the registers. This has kept the funky smells down in my vehicles for many years.

I'm sorry that this got so wordy. :nerd:

Enjoy the heat my friend,

WBW

The high Relative Humidity levels have a lot to do with the condensate line from any A/C system running like a garden hose . . . :x

Thanks WBW. Thought that might have been it, but the volume was surprising. And yes, I have kept up on the cabin filter, but will have to try the compressor trick you mentioned. Much appreciated! Now its time to take the truck out and play in the mud :)

I always do this and I think (could be wrong maybe placebo) it keeps the AC components from prematurely waring out.

Funny - I had the exact same concern last week when I found a very similar looking puddle under my truck in the exact same spot. I arrived on a semi-remote job site and started to unload and setup when I noticed the truck “leaking” on the concrete pad. I had the truck heavily loaded while driving through the mountains on a hot day, so after my initial moment of dread (and a quick flash of brainstorming a trail fix to limp home), I crawled underneath the truck and dabbed a finger in the puddle. Confirmed it to be water without a hint of antifreeze. It was also an abnormally humid day for us which explains the abnormal amount of condensate.

Remember guys that air conditioning is NOT just for blowing cold air. It is for humidity control. ALL types of air conditioning (truck, house, plane). The more humidity in the outside air the more your system is going to have to "control." More "control" will produce more condensate (water) byproduct.

Now the lawyer part: YMMV.
