I cannot say enough about Chris. He was the lead on an a/c installation team. He called 30 minutes before arriving - and arrived at the scheduled time. He was very pleasant, and knowledgeable. He answered all questions to satisfaction. Chris explained the entire process, and how the two-stage a/c worked, as well as what to expect from the heat pump, as I have never experienced how a heat pump works. When finished, Chris cleaned up everything as though he had never been there. What an exceptional employee!
