I just had C & J Air Conditioning and Heating Co. come out to my home to do their Winter checkup on the heating unit. The service turned out just fine. I have used them several times before, so I absolutely would recommend them. Their technicians are always very nice, prompt and professional. I am always very pleased when they come out. I will have C & J Air Conditioning and Heating Co. out again soon to do their annual Spring checkup.
