Looks like a PRIME candidate for ozone shock treatment! Not to mention, I wouldn't work in that space till after the ozonination had done its thing to kill all the nasties in the air and on the surfaces. Don't fool around with mold and mildew-- even the "harmless" varieties aren't good for you!

I'm sure everyone here knows that with the new SEER ratings requirements, there are a lot of new condener units being installed. The problem I've found is that homeowners frequently insist on keeping the existing evaporator coils in place in their air handler. While I'm pretty good at explaining to homeowners why they really, really should replace all of it at one time, I'd like some suggestions on how to get the point across better (other than the obvious energy savings and the benefits of having "everything the same and matching"). Thank you in advance for your ideas!
