Can someone suggest a homeowners warranty company? -

I have a homeowners warranty already but it expires in January. I only had to use them twice and they seem to be ok. It being that I had no knowledge of how to choose. Can someone give me suggestions on how to pick a homeowners warranty package or has anyone had good luck with a particular company that is reasonably priced? I live in central Arizona and need one that has good a/c coverage due to the heat in the summer. Any suggestions are appreciated. Yes, Countrywide offers one. Either under the name Countrywide or Balboa Insurance. Call 800 669 6657 and ask to speak with someone in sales.
