This was my first time using Complete Comfort Heating and Cooling, I heard about them from my brother who has been using them for a couple of years. James was the technician who came out, he was wonderful and answered all my questions. He taught me about a new type of freon that is being used after I had mentioned wanted a new air conditioning unit in a couple of years. He cleaned my air conditioning unit, put in a new filter, and did a safety check. He also took a quick look at the furnace. Everything works well and I am happy with the service. Highly recommend to others!
