Some time ago I was talking to a person from acompressor manufacturing company and he happened to mention they are unable to find anything wrong with about eight out of 10 compressors that are returned in warranty.
This is a sad commentary on the expertise of a large portion of our country’s service technicians. And what’s more, this is a lose-lose-lose-lose problem. The contractor loses because the problem hasn’t been corrected. The customer loses because changing a compressor usually results in a contaminated system where the next compressor will fail all too soon. The supply house loses because it now has paperwork to fill out and old compressors to store, and the manufacturers of the equipment and the compressors end up with scrap metal that can’t be used again.
