Situation: Trane A/C, less than 4 years old, began to loose gas about a year after installation. The company came out one time - could not find the leak topped off system, paid for service. 7 - 8 months later, low gas, changed the condenser coil still under warranty, paid labor and gas. About the same period of time later, low gas again.
I called someone else - for obvious reasons - and, after using a detector in all accesible places, he suspects the leak is in the wall, possibly caused by baseboard nail (house is modular, sheetrock was already up before A/C, but not the baseboards, chase already builtin to the attic). The strategy is to open the wall in a couple of places around the baseboards (two story house) and take a peak.
I am concerned that the leak may be due to the original installer crap work where he joint the tubbing somewhere in the wall, so I am thinking that after cutting my walls the leak will not be found.
I am thinking about just replacing the run in the wall from where it enters and exits the chase - approximately 25 feet, and skip the time for wall exploring.
Thoughts? Cost of one vs the other, especially if the leak is not found during the first look into the walls?
Regards
