We had a home warranty for two years after we bought our home a few years ago. In my opinion, our warranty company used semi- knowledgeable service people. Service was somewhat spotty and we had to use whomever they contracted with. We live in the south and our A/C went out in July. The company said it would be a week before they could send someone out. Our hot water heater broke and it was over a week before the incompetent service rep could fix it. I truly think he was a plumber in training. We dropped the warranty after the second year. Hopefully there are better home warranty companies.
