I noticed a musty smell when I turn on the AC, so I researched and found that my evaporator coil might need to be cleaned. So I opened up the panel where it should be, and it looks very different from the ones i have seen ******. The ones I have seen are A-framed, and either this one has only one side or the other side is obscured and I need to take more things apart to get to it completely. Can someone look at the photos and let me know if what I see is the entire thing, or how I could access the other side of it?
