Hi everyone,. I'm new here and this looks like a site with a lot of good info. I have a air handler that is leaking from the main pan into the secondary pan. If the hole or leak is not too bad is it repairable like filling it with some type of caulk or fiberglass resin. I got a repair estimate of 1,800 dollars to change out the air handler. I gues that includes a new coil. It would be nice to be able to patch the leak and get a little more mileage out of this. Any help would be welcome. Thanks.
