We have used C & J Air Conditioning and Heating Co. for a long time and recently have not been happy with them. They do the maintenance on our HVAC system and do a good job on that. The problem is they do not communicate with us when they find a problem. We have to call them back out to do the work, which may end up costing us another service call. At this point, I cannot recommend them even though the servicemen are always pleasant and courteous when they come.
