I need to get my A/C condensate drain/line fixed. (This is in an older home
I just purchased.)

The problem the home inspector pointed out was that it drains into the same
pipe that the clothes washer does.

Also, the other day the A/C was running, and water was dripping over the
furnace from the line. One joint was leaking, and also the line isn't
sloped enough to allow for proper drainage.

I've got some questions:
(1) Is it true that this is work for an A/C guy, not a plumber? I called a
plumber, and he didn't want to do the work and said call an A/C guy. I'm
asking, because at least where I live, it seems like many A/C guys are one-
or two-person shops that are hard to get ahold of (and might not even have
an office).
(2) The plumber also said that the way the A/C condensate line/drain should
work is that it goes to the floor, and then some pump pumps it out of the
house through a line going through the basement wall. While I can see that
the current setup is dumb (condensate can't really drip into pipe when the
hose from the washer is in place), is it true that someone can't just add
another "branch" to the PVC pipe the washer is draining into, and have the
condensate drain go into that? I guess maybe that's not such a hot idea,
since maybe the stuff coming out of the water is under some pressure, but
the whole business of drilling a hole through the basement wall sounds like
a lot of work.

TIA,
