Today, a Service Pro, Mark, came to go through the fundamentals with me on how to change from Warm to cold, and reverse. With his explanation, I am confident that I can now do this correctly. Before,--- not so much. He was very efficient and thorough, and I might add, patient with me. I have enjoyed meeting each of the ""boys"" I have met with Kliemann Brothers The company has my respect, and so does Mark. Many thanks. Great company! S. Foster
