Rust around indoor coils

[mgfarmer]

I am new to this hvac stuff and noticed whent he tech came out today to work on my indoor blower that there was some rust around the coils where it enters the galvanized plate(not sure what its called that holds the coils). The unit is only 3 years old. Is it normal to see rust where the coils meet the metal and could it cause problems?

It's normal, and as long as the copper holds up, your fine. Very common.
