C & J Air Conditioning and Heating Co. do the annual maintenance and inspection for my HVAC unit. I have used them for 20 or 30 years now. They always arrive on time. They are careful when they are in my home, wearing booties to keep my floors from debris. They are knowledgeable about what they are doing, and they do not try to push extra services on me. It is a rare occasion that I have to call them on an emergency basis but when I do they are quick to get to me. I appreciate them, and I will continue to use them for my HVAC needs!
