Hello and thank you in advance for your advice.
First off, I am not looking for DIY advice. Here is my problem. I have an R-22 Trane XE-1000 (mfd year 2001) 2 ton system. I recently had the unit inspected for a suspected leak. My local contractor came out found the leak and told me that I needed to replace my system (outdoor condenser and inside coil, and lines, etc.) due to the leak. He stated that it could not be repaired. I was curious as to how he knew he couldn't repair it when the leak was on the condenser(?) on the outdoor unit. The unit has small Al hairs/fins coming off it which makes the actual leak invisible to the naked eye without removing those fins. Is this SOP for units now, they just need replaced when they break? I ended up peeling the fins back to the leak after he left. There is a crack in the line where the Al tubing was slightly kinked. I noticed though that the line in the coil is definitely Al. Then approx. 4" prior to the crack the line is copper. Obviously at some point Trane was able to join copper to aluminum, but I thought this a fairly delicate procedure. Would cutting this fatigued section out and brazing in a new copper or aluminum line be feasible? Can a swagelok fitting be used at the AL-Cu joint? Can this unit be repaired? I called this guy b/c he was listed on the Trane website, but something just doesn't seem logical about his diagnosis.
I realize that I need to replace my system soon, but not really wanting to do it so soon, with the R-22 phase out. Even if I could limp it along for another 2-3 years would be spectacular.
Again, thank you for your advice.
