I have used C & J Air Conditioning and Heating Co. three times now, in buying three air conditioners. I have had a very good experience with them, although they can be short-handed sometimes. They are very nice, professional, and very courteous. There was a small problem after the installation of my unit was completed, but when I called them up, they came right back and fixed the issue. They were respectful of my home, and they did an excellent job with the installation.
