If the furnace is collecting this dust then the evaporator coils are too, probably more so. And it doesn't get burned off - maybe washed off a bit by the condensation. Use the better filters.

Wow, that's good stuff. I also use the high efficiency filters, but the way the intake is set up in my house, it's not a sealed system. It actually sucks right through a not air tight "tunnel" (the unfinished inside of the walls) up the middle of the house which means that it's sucking through the walls and dry wall. Not the best setup, but I guess that's the deal with a house that was built in 1967.

That's what makes me worry about the fins of the evaporator getting dirty/clogged. I think that's probably a job that I could do. Do they use one of those fin combs to clean them or what?
