The drain pipe in my trane xr13 air conditioner seems to be clogged, or at least that is what I'm being told by a lot of people. The unit is leaking in the garage and I am not sure where to find the drain pipe to empty and then add bleach, like many people are telling me to do.

Have you got a shop vac. Suck it out, most of time this works,just wrap some old rags and/or tape around the line and vac hose to pinpoint all the suction in the drain line

wmproop, thanks so much. The funny thing is, I cannot locate the drain pipe and it's driving me nuts. Is it outside or in the inside unit? Thanks.
