For the first time in 15 years my A/C drain stopped up. Since the
drain is from the attic area then connects to another A/C in the
basement I had to undo the basement line, stop it up, then blew
compressed air into the line using a blow gun hooked up to my
compressor. I have no idea why it was clogged or what was in there
(anyone know?). After using the compressed air the water began to
flow out. I was wondering the typical procedure for cleaning a (long)
A/C drain line. This line is PVC pipe. A neighbor suggested using
household bleach to clean it out.

Did you do this at the place where it came out of the coil near the furnace?
If so, you did it right.

I usually find where the line dumps outside and use a wet vac.
