For whatever reason, for the second time in two months my 11-year old central AC is not cooling my house. Nearly two months ago it stopped working and I had the large outside unit (condenser? compressor?) replaced. That solved my problem at that time. (FWIW, the unit is a Payne.) Now I'm having problems again; (Another pain.) Both the outside unit and the attic unit are running. Water is dripping from the release pipe on the back of the house, and there's a small fraction-of-an-inch of water in the pan in the attic unit. Since I know nothing at all about air-conditioners, I'm wondering if there might possibly be a very simple remedy which even I might be able to fix. I've already notified 2-10 Home Warranty and have gotten a work order number. I then called the local repairman suggested by 2-10 and left the work number on their voice mail. Even so, it would be much better if I, or perhaps a neighbor, could fix the problem today and keep the repairman away. I would greatly appreciate any advice you might offer. Thank you.
