I had my 2 year old AC unit serviced including a cleaning of the coils after it was leaking water and now it has only been 2 weeks and it's leaking water again. The drain to the outside is working properly. The filter is barely dirty. Could it be a clog in the capilary tube or a coil issue? How can I check this out myself?

It could be improperly installed and tilted away from the drain where only some is draining outside... or a partially plugged drain.

Hey.. I think AC Repair Houston (http://www.airdepot.com/) will understand your problem completely and guide you accordingly.

I took pictures but not sure if this site will alow it. It appears to be dripping where the connection inside the handler is that goes out into a pipe may be cracked
