I was very impressed with AC Comfort Consultant Jacob Dicken whom I consulted regarding an AC system via Home Depot. He is very knowledgeable and willing to share that knowledge. He knows a lot about the whole AC business. I haven't decided on a AC system yet but I would like to work with him again. I may want to get AeroSeal done on the air ducts and also have more insulation blown into the attic prior to installation of a new AC system. For now, I am using a MasterCool cooler.
