I noticed my furnace sweating a couple days ago. It's hot and humid where I live so I was only mildly concerned. It was a high of 74F today with humidity around 70% which is, relatively, nothing. My thermostat keeps the house around 72F.
Lately, I've noticed that my A/C is running 90% of the time (a lot), but chalked it up to this being the hottest month.
Side of Furnace with Sweat Drops
Good Size Water Trail on Floor
Two Small Streams Coming from the Other Side
Condensation Runoff Line
It looks slightly kinked, but has been that way since before the summer. I don't know what the blue tube is.
Just for Fun: This is How the Condensation Line Connects to the Main Sewer Line :D
Is this bad? What could be causing this?
I've researched online and found some informal sources that say something in the airflow is being blocked/clogged somewhere...

The System as A Whole
At the bottom of that "V", where the grey and off-white metal meet, is where Picture #1 above was taken.
Inside the Upper Front Panel
I think this section only has to do with heating, but I don't know if you guys see anything useful.
The Rear Panel
It looks like I can unscrew that entire rear side, but I won't do that unless necessary. There is also a smaller panel in the top of the photo. Should I open that?
