Air Conditioner Evaporator Coil Condensation Drips On To Filter.
I have a Trane air conditioner model TWG030A140B1.
The air handler has a single evaporator coil mounted vertically at about a 45 degree slant.
As condensation builds during normal use, the water will trickle down the fins and into the catch pan and the out the drain pipe.
Water drains great, no issue there.
The issue is that as some of the water trickles about half way down the fins it then drips straight off of the coil and onto the filter.
Eventually the water will pass thru the filter and collect on the floor.
I’ve cleaned the evaporator several times with a garden hose along with different store bought cleaners as well as dawn dish soap with a soft bristle brush.
Still have the same issue. Nothing works.
Fins are in great shape, nothing bent up. Nothing plugged up. I can shine a flashlight thru the coil.
Again, this is not a drain problem, catch pan problem or trap problem.
Seems like a surface tension problem.
Any suggestions?

I’m am having the same issue.
Condensation drips from the coils directly on to the filter below. The filter will be come saturated and begin getting sucked into the unit after about 10 - 14 days.
We have cleaned the outside of the coils with a spray on foaming cleaner and soft brush. Then rinsed thoroughly. I can see light through the coils when a light is shined through with no issue.
Tell me, do you also have regular problems with your air conditioner? I've been having the same problems since I bought mine. I don't even know if I need it as much as I thought I did before.
I totally get how frustrating that dripping issue can be. It's cool that you've tried various cleaning methods, and it's not a drainage problem. I had a similar issue a while back, and you know what helped? I contacted Hot 2 Cold Air Conditioning https://hot2coldairconditioning.com/, a reliable provider of air conditioning services in my area. They were super friendly and knowledgeable. They advised me to get a hydrophilic coil coating, which reduces surface tension, allowing the water to flow down the fins better. You can find it at most HVAC stores or online.
