We use C & J Air Conditioning and Heating Co. to have our heating and air conditioning systems checked for the summer and winter months, and they have always been very quick and efficient! We've been with the company for quite a few years now, and they're very timely in sending us reminders about getting our service work done, and they always call to set up our maintenance appointments! The woman who works in their office is very efficient and very nice, and the workers who come out are very professional and friendly! I have absolutely no problems with any of them. I've already recommended them to others, and I will continue using C & J to keep our systems up and running!
