We purchased an AC unit from them 7 years ago and it came with a 10 warranty. They came out and looked at the unit and our compressor is out and now they are telling me that the warranty is not good. The first reason I was give was that we did not register it online so it was not good then I told them we were never told it had to be registered, and that the registration paper was still inside the unit when they came to work on it so how would we have even known to register it. Then I was told that the warranty is only good if they do maintenance on it 2 times a year, and the warranty paper does not say that anywhere on it. So, I asked where it says on the warranty that we had to have the maintenance every year and he said that it's not on the paper, but I would have been told that. When I said I was not told that and asked for a copy of the paperwork that says I turned down the warranty he does not have anything. read more
