I recently went to Duncan's in Lincoln to get my AC compressor fixed. The serpentine belt had broken on a road trip across Nevada and the mechanic in Ely replaced it but when he started the car up again the AC compressor quickly overheated. He disconnected the electrical connection to it and it stopped overheating so at least the clutch in it had failed but perhaps there was more damage. So when I got back to Lincoln I went to Duncan's to get that fixed and to get the oil changed. I was quoted $1868 to replace the compressor and then they also said that since there was a lot of corrosion on the battery terminals they needed me to spend $428.90 to fix that! In addition, they said I needed my fuel injectors serviced for $190. Luckily for me I couldn't leave the car overnight that night so I took it home after they did the diagnosis and I spent a few minutes cleaning off the battery terminals and did a rudimentary test with my voltmeter which seemed to indicate everything was fine. I told the service advisor of this so they checked again and verified that no service was necessary. When I picked up the car, all they had done was what was necessary to fix the AC compressor. They did not change the oil or service the fuel injectors. When I pointed this out to the service advisor he said that oils are so good these days that the car didn't need an oil change and that no service was really needed on the fuel injectors. So they were trying to get me to pay $428.90 because my battery had some corrosion on it when all that was needed was to clean it, and they were also trying to get me to pay $190 for fuel injector service which I was told was also not necessary. I feel that this is a very dishonest and disreputable way to run a business. They were obviously trying to get me to pay for service that was not necessary. I honestly don't know if they oversold me on fixing the AC compressor. By my understanding, when the clutch goes and the compressor overheats, it can cause more severe problems where the fluid gets contaminated so the lines need to be flushed and the fluid replaced. And that's what they did, the maximal amount. I have no way of knowing whether or not the only problem was that the clutch died and needed to be replaced. Perhaps, perhaps not. Given what happened with the battery and fuel injectors I'm left wondering whether or not they were honest about that too. So I would not recommend them because I don't think they can be trusted to honestly do only the service that is necessary.
