I have C & J Air Conditioning and Heating Co. several times and they always give me great service. In fact, they installed my current unit several years ago for me and they have been servicing and maintaining it ever since. They are friendly and professional people and I like the fact that they take the time to explain to me what is going on. I am a curious of type person and I want to know what is happening. I highly recommend C & J Air Conditioning and Heating Co. to everyone. They are a very good company!
