I have a disconnect between what my home warranty says it needs to reimburse me for my external 3.0 ton unit and what the technician is willing to write regarding the condition of the unit before it was replaced. I will try and keep this short: My home warranty's techs failed to come out and service my home unit, and they authorized me to get my own tech to come out and see about it. The internal temp of the house was 89 degrees, and the fans were running but no progress was being made. The inside filter was clean, the coils were not frozen up, the outside unit was free of debris, and according to the tech that came out, the system was almost 100% charged with freon. This was the 4th time (once a year) I had called this home warranty to fix this same unit, and each year they filled the compressor with freon, and it worked again for another year. But not this time - the last time, they repaired a leak, and left another leak unrepaired, saying that it was in an area that couldn't be repaired (near the valve). When the temp went up in the house again, I just assumed it was calling for freon. Anyway, the tech I was able to get out to the house is from a highly reputed company in our area, and he said that the unit was just worn out and needed to be replaced. He reluctantly put this in writing, knowing I needed it for my home warranty to authorize the replacement. I have no doubt that this was a true statement, but "the unit (compressor/condenser) is just not able to keep up due to age and inefficiency; unit is beyond all reasonable repair" is not technical enough of an explanation for the home warranty people's books. They want the exact failure reasons for each of the major assemblies in the exterior AHU. I went round and round with them explaining how if all the parts are worn out, and you replace one, then the old one next to it will fail, and so on. No dice. I even contacted a consumer lawyer, and he says the explanation given should be enough for the insurance co. My question to all is: What can be said in a technically complete way to adequately explain this situation? I am an engineer, but this is not my field (ME).
My attorney can get the tech a signed release of liability so that he and his company will not be at risk from lawsuits for answering the questions. I read in one of these internet reference sites that there is a standard guide that determines whether to recommend replacement or if repairs are warranted. I have no idea where to find this guide, but it might be the missing piece of the puzzle. Any help at all will be appreciated, because it is not possible to actually dissect this unit anymore.
