Reversed coil???
I had a brand new trane installed in april. I have been wondering why my humidity spikes everytime the unit turns on. Well I noticed a decent amount of water in the drain pan. I looked inside AH, and noticed insulation very wet, and looking inside i noticed the coil is reversed! The bottom of the "a" is facing the blower, return air is passing through the top of the"a". I see water dripping down...and I assume is blowing through the blower and into the ducts when its running, and i guess is why the pan is filled.. The coil sounds like its reversed...correct??? I will be calling installer tomorrow. Should i request a brand new AH since its been getting wet since april? Thoughts and suggestions please. Thanks.

Need pictures, but if the air handler is installed in the horizontal left position, the coil i supposed to be flipped with the apex of the coil facing into the return.
If more government is the answer, then it's a really stupid question.

Supply----fan-coil>---------Return air

Could be an install (or dirty filter) problem. May have to get someone local to check it. Originally Posted by suzook

Filter is clean....check out my link. Why does that show the apex pointed toward the fan, away from the return???

What is the model number of your air handler? Originally Posted by suzook

If you indeed do have a TWG air handler, the apex of the coil should point towards the blower.
It isn't actually possible to flip the coil on a TWG air handler, without field modifications, and would result in the drain pan being above the coil if the unit is installed with the supply on the left.If more government is the answer, then it's a really stupid question.

Your right, its not that model. Its the latest vs ah from trane. I just don't understand why the insulation under the blower is wet, along with corrosion on the wire terminals already. Guess I will call the installer back. Any suggestions?

better call your installer, has it done this since day 1? might have a plugged drain which would mean all the humidity in your house is going back into your house and in your unit Originally Posted by suzook

As I recall, some of the Trane airhandlers required a larger metal plate be installed at the apex of the A coil for certain configurations. I don't know if the current production requires it as I've not worked for a Trane dealer in 4 years.

They come equipped with the apex baffle that will work in all configurations. Originally Posted by allan38
