I have a Lennox Central AC unit in my garage. I noticed water seeping behing the door. I found that there was almost an 1" of water in the AC compartment. I removed the cap to the drain and water came pouring out. Do I have a "clogged drain pipe". Here in FL, the AC runs 24/7 for months. I don't know how long this situation has been going on. Is there a way to unclog or clean out the drain? Anything I can put into the pipe like drain cleaner to help this matter along?:confused:

First thing to try is to take the old shop wet/dry vac to the drain suck that sucker out real good.
