I have an AC question; I have My AC unite in the ceiling Coils and compressor are outside. Well when my son said there was a large spot in his ceiling I knew what it was, the condensate pan under the AC was at the brim dripping over, But the over flow line was dripping outside so I did not suspect any problem. I shoved a wire down the line from the pan, Then I sucked the line out with a shopvac from outside , that cleared the line. There are two lines from the unite One with a trap and clean-out that should be piped to a vent or waste line. (Ten days of 100 plus to hot to trace) Now the other line from unite pipes into the line from the pan the out the house. Now here's were I'm getting confused. Before I cleared the line the was a constant drip from the overflow line (almost like running that much water) Now that I have cleared there in no water what so ever the pan is dry. The AC is still running on over time until today finally cooling off. So why would there be no water Condensation at all now? I would think condensation would still form.
I am also replacing the pan looks like is about rusted threw ( 14 years old) the condensate drain line looks like something a kid did , unless they engendered a hump over a backbone. The new pan will be Stainless, Aluminum or copper with a copper drain line , 10" straight run less the hump.
