I was very pleased and grateful I had Ryan do the sale. He was easy to talk to I felt he was honest fair and willing to answer questions. He gave me time to respond. He called early this am to advise the team would be late. It gave me time to start my day. The team that came Chris and Jordan were also kind pleasant and willing to explain things. They worked fast and efficiently. They didn't bother my dog asked for permission to come in the house. This is a big expensive decision to make quickly. I will gladly promote Diamond AC Polli in Tempe.
