When our A/C went out, we sought estimates from three different local companies, A-1 being one of them. Chris seemed very knowledgeable and, if a little forceful in his delivery, friendly enough. We did our research on the system he recommended and decided against it, selecting a different company who has given us good service in the past on our heating system. They recommended a cooling system we felt was better for our needs. When Chris called to follow up and learned we’d selected his competitor, his attitude quickly turned snarky and insulting and, in my view, unprofessional. While I might have recommended his services to someone else who needs HVAC services, after that«conversation», I will not be recommending A-1 to anyone. I have him two stars instead of one because, as I said before, he seems to know what he’s talking about and would probably do a good job installing the system.
