Let me preface this by saying that I know absolutely nothing about A/C systems and the little that I may seem to know about them from this post is just what I learned today. I didn't even know what an evaporator coil was before doing some research today to help solve my problem. I have noticed that my A/C unit hasn't been pumping out a lot of cold air recently. So I figured maybe the filter just needs to be changed even though I just changed it a couple of months ago. When I got to the filter, it was wet and partially folded up like a lawn chair sucked up into where the evaporator coils are. Then I realized that the floor was all wet. So I shut off the unit and breaker and removed the cover to find THIS: (disregard the dirty filter next to the unit - that was NOT the filter in use at the time this occurred. That filter is just the filter that came with the unit years ago and was never thrown out) [IMG]http://i14.photobucket.com/albums/a346/niceguymr/IMG_2303x.jpg[/IMG] I think it's safe to assume that the leak is not a drainage issue, but simply water that's dripping from the melting ice, correct? So after doing a little research, I'm learning that this may be due to a dirty evaporator coil. So I looked up inside and I guess it looks a little dirty however I don't know what a real dirty evap coil looks like. Here's what I see - There are 2 cavities - One is 'A' shaped with 2 sides of evaporator coils and a 2nd cavity on the right just has one evaporator coil (it also looks equally dirty) [IMG]http://i14.photobucket.com/albums/a346/niceguymr/IMG_2304xx.jpg[/IMG] As a preventive measure, I've already called out a service tech to come check out my system (It's included with my annual service contract) but I'd like to know what's going on before he tries to sell me on soemthing like having my coils cleaned. I'd like to also know if this is something that I may be able to do myself. This unit (and a 2nd one in my home) are only about 2 or 3 years old, so I don't want to spend a lot of money if I can do it myself. So I'd like to try and clean these coils myself if I can but I want to know how to do it right. I bought this stuff at Home Depot.

I'm trying to get an understanding of how / where exactly this stuff is to be sprayed. If I understand correctly, I would be coming up underneath the unit (following the path of the green lines) and spraying the inside side of the coils (indicated by the red lines). So once I spray this stuff on the coil, I imagine that it's going to be dripping down and there I will keep something on the ground to catch all the gunk. Will there be any need for me to brush or rinse the coil further? [IMG]http://i14.photobucket.com/albums/a346/niceguymr/IMG_2302xx.jpg[/IMG] Please let me know if I'm understanding how to do this correctly. I don't want to start spraying stuff up in there only to find out I'm doing it all wrong. Any help would be appreciated.

I damaged outside thermostat line with weedeater. Checked all wire nuts and no lights on inside control board. I believe that the 120/24 transformer is blown because the wires were exposed and touched on contact. Can not find fuse near transformer
