I am very impressed with the professionalism of Kilter mechanical tech. My father has been In the refegeration business for over 20 y he is in another state. I would cross-reference any information and recommendations from the tech with my father and it was always correct. Before I called Kilter I had other ttachscome out and what they were saying and the prices they were giving me did not add up. It is extremely hard to be in a new state and not have references to go by. I am glad I found an Ac tech that I can trust is prompt and efficient
