They were the best that's ever worked on my system. He replaced a compressor and all other parts that needed to be replaced. He looked at my unit, gave me a price, which in my experience was more then fair, showed up the next morning and by early afternoon was finished. He put a 2000 more btu then what I had and because of that the system puts out better then when it was new. When my old system does die I will be getting my new system from Wade Knox. Thanks Wade.
