I have a 2 ton A/C unit (r22) which runs to a closet air handler. I had been having to recharge the system about once or twice per season. Using a freon detector I could tell that the evaporator coil was leaking and decided that I didnt want to leave a leaky coil for the next owner (I am moving soon). My old coil, which worked fine overall was a single flat piece angled from down in front to up in back. The filter is mounted below and the fan is mounted above and pulls air from below, through the coil and out to the house. I bought a new coil, same height and width (mostly) but a bit thicker. Piston is .059, which I believe to be correct for my R22 unit. The placement of the coil was fairly easy but the install was a bear, mainly due to difficult positioning of the output. Eventually it sealed up, held a nice vacuum and the was filled with R22. The system blows cold air now but as soon as the blower turns off, there is so much water in the fins of the evaporator that it drips down in to the filter. Not just a little either. Worse than that, I can tell there is so much water inside the air handler that the wires inside are wet. The day we put it in it was very humid. But this seems excessive. I don't ever remember seeing much water on the previous coil and I never had water on the filter. I'm at a loss as to why the new coil is acting like this. Can anybody give me an idea what is going on?
