Should I be concerned / what to do?
So I have a ~4yr old system and I do the preventative clean coils + clean debris out of compressor + flush drain line stuff myself once per year, did not notice this at all back in May when I did that last but was outside on some non HVAC related business today and noticed this bit kind of peeling up with some rust or whatever. Should I just scrub it with like a rust cleaner and use a sealant/adhesive to keep that bit down or what?
