Maybe not.
I had one yesterday. Frozen solid.
Nine year old Carrier coil with a leak and severe corrosoin.
I'm replacing it tomorrow.

OK, I'll have to trust you on that one. But if it's leaking
refrigerant, how can it be working well enough to ice up? Maybe the
leak is real new and most refrigerant is still in there? My admittedly
limited knowledge would indicate that if the system is leaking
refrigerant it will burn up compressors, not ice up coils.

Also, the OP said the ice was in a ball on one of the pipe connections.
That makes sense--I see it a lot in systems at work. The moisture
condenses there where it is very cold, not much air blows across to
melt the ice, and the ball forms. I expect that this would be
independent of any leakage. It would also indicate that some
insulation might be in order.

Oddly, a low charge makes it run colder and ice up:

Don't confuse temperature with heat. The fact that part of your evaporator
is below freezing temperature doesn't mean that it is moving much heat.

I would play it safe and get another opinion. My a/c is still running
after 15 years and it was not top of the line.....nothing has been
replaced. It's checked yearly...

That was interesting. I never knew that. Dang, learned something
today, and the week isn't even over yet.

Thanks.
