About the unit: It is a carrier split unit. Electric. Provides heating and cooling. Sorry, I don't know much more about it than that. This particular unit cools the top level of my house, which is actually 1 large room about 800 sq ft.
I've tried to resolve the issues and have come up against a few things that needed to be taken care of but its still not working as it should.
Originally, the airflow coming out of the vents was weak and not cold.
I have an electric air cleaner so I took out that filter and cleaned it, along with the main part which I believe does the zapping (sorry, don't know its name).
The blower motor spins fine, and when I have the side panel off the airflow from the outlet vents is strong which lead me to believe it was a blockage between the inlet and blower motor. I ran the system without the electronic air filter and the airflow still wasn't strong or cold which left the evaporator coil.
I used a can of this stuff, which brought some crap to the surface. I sprayed it on both sides. I used a soft brush to brush that crap away.

I then purchased this and used about half of it so far:

And then, for good measure, I took my steamer and steamed it (although I didn't do this for very long). The steam seemed to go through the coils without a problem.
I ran the system. The airflow is much better, but I think it should be better than it is. The temp isn't dropping below 90, usually hovering around 93. I used a infrared thermometer and after the unit has been running the temp difference between the inlet and outlet is only 3 degrees. I believe that should be around 20.
So, I opened up the system, and there is some icing along some of the lines. Its not along the main coil units like I have seen on some images/videos.
I also took a picture of the coils. Its hard to get our head in there, and from the picture it looks like it could still be a bit dirty, but I'm wondering if that would be enough to cause all of these problems? I thought I had cleaned them up but looking at the pictures I'm guessing not. I noticed a few bugs in the picture, I'm wondering what's going on in the parts I can't see. Would using a compressor to blow from the bottom up be a good idea?

After taking the picture of the top of the coils, it looks like its not as clean as I thought it was. But can that still be the sole cause to this problem? I was thinking of getting another couple of cans of the Web coil cleaner to give it another nuking. Although I may try some hot water and dish detergent first.
Is this a Freon issue? I had the outside condenser unit replaced about 2-3 years ago (original was stolen).
Does anyone have any suggestions?
Thanks in advance.

Dirty coil the problem? Or multiple issues?
