I live in a fairly small home, built in 2007 (I'm in Florida). I've been curious to know how dirty my coils were and looks like even to look at them is not a task for myself (would have to remove said coils). It's basically a gas unit with another air conditioning unit attached to the top of it.
The coils (from the angle that I can see them), look a bit weathered for only being a few years old?
I also noticed there to be this black stuff on the duct leaving the coils....is that mold? Normal?
I've attached some action shots.
