Evaportor coil leaking in 25 yr old AC/Heat pump. What's the best option?
Have a trane air handler unit installed in 87 when the house was built. The contractor showed me that the coil in the air handler was leaking in multiple places. I'm guessing the coil is appoximately 18" wide by 30 " long by 4" deep. He said you couldn't buy them anymore, and they were near impossible to repair the leaks. It's a 2 1/2 ton unit, with an American Standard compressor outside put in in '96. There's a very small leak on the outside unit on the valve they hook the gauge to. He told me the best option is to replace the entire system with the same size Goodman.
Is that the best route or should I pursue trying to only have the coil replaced? Other than the leaking I haven't had any other issues except having a capacitor go out.
