Its just a phase you system is going through. It usually takes about 3
months and then it stops happening. Just ignore it. It will go away.

Maybe you should call for service

Get in there and clean that twenty year old sleazy, scummy,
drain pan. That probably has bacteria growing for the last twenty
years. Or, call a licence professional to clean your mess. And then
complain how much it costs. Some times our job is real glamorous.

I probably will be calling a professional tomorrow to get some quotes
on fixing it - I just wanted to make sure it wasn't something simple
like a plugged drain somewhere that I could fix myself. I'm mostly
interested in what's causing it and being able to understand the issue
before the technician gets here so that I can talk about it
intelligently, not just mumbling the "water everywhere air conditioner
help me help me" babble I posted above.

BTW, we've lived in this house for a little over a year, and both the
A/C and furnace were serviced in the month before we moved in.

All you need to tell the tech is that its leaking water, then let him/her do
their job.
FWIW, I don't know of any company that does estimates for *repairs*, only
for new systems.

FWIW, it needs to be serviced twice a year...once in the spring for cooling
and again in the fall for heating.
