I can't possibly sell this house if it's leaking water like this... even if they didnt notice.. I think I'll try the different piston size. I think it's fairly easy to switch out. And I certainly don't want to take the whole coil back out. The system is entirely vertical.. air in the bottom and straight out the top in to the ceiling. It's a wall mounted, all electric closet system. And it used to work pretty well until I decided to fix the leak.... Thanks again for your responses and your time. If that doesn't help I'll call a pro out. Michael

Thanks for the response. "Exact"? The system is very old. I'm not sure if the evaporator coil is part of the tempstar cooling unit or the fedders heat/air handler unit. Whatever the case I couldn't find an exact match. Old coil was 16x17x2 while the new one is 16x16x2.5. The piston on the new is .059 which I believe is correct....but I'm basing it on a chart I ran across online. Could that be wrong? It's a 2 ton unit. The new fits nicely where the old one sat...gross size is essentially the same...had to put a couple holes in the frame to screw it in to existing holes. It also sits at

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.
