Almost immediately upon starting up my AC, the refrigerant line inside the
evaporator coil and 2 or 3 of the bottom-most coils frost up and then
later ice over. The coils above that never seen to get cold at all. The
blower motor seems to be functioning properly as airflow seems normal. Is
there a leak in the system, anything else I should look at before calling
service? Thanks.

Either you live in a trailer, or your screwing around with something your
shouldn't be.
THere are a couple of things you can check tho... like maybe change your air
filter more than once a year, and make sure all your vents are open. Beyond
that, call the tech.

Don't live in a trailer and have a basic understanding of AC. All the
research I've done on a partially frozen coil pointed to what I posted, so
I'm not sure why you have an attitude. I also change the filter every 2-3
months. Thanks for the informative reply.

OK... you say you have a basic understanding of the refrigeration cycle
(A/C)
Answer me this... what will cause a frozen coil?? (hint- there are only 3
things)
The vents and filters will normally fix the first one.... until some idiot
takes the covers off a cased coil while the system is running and wonders
why it frosts up.
The other problem will need to be corrected by a licensed technician.

Well, what I read that applied to me was that poor airflow (dirty filter,
bad fan belt, ductwork blockage), low refrigerant or a leaking coil
would cause freezing. I didn't take the cover off a running system to see
that they were iced. There was freezing on the refrigerant line right
where it begins to enter the coil, which is visible without removing
anything. After running it for a bit and not getting any cold air, I
removed the panel and found further icing inside.
I simply wanted to ensure there was no simple thing I was overlooking. I
like to be informed about how things work, what causes problems and
generally be informed when a technician arrives. It doesn't matter if
it's my HVAC, my car or anything else. I know when I'm in over my head
and need to hire a professional, which I intend on doing first thing in
the morning. I didn't realize that wanting to be informed was such a
crime around here.
