Wally called to let me know he was on the way, as always. He arrived in a timely manner, began the task at hand. He was his usual friendly, professional, competent self. I have done business with Sears Heating and Cooling for decades and Wally for many years. I wouldn't use anyone else and never will as long as I am a homeowner. I highly recommend Sears Heating and Cooling and Wally for competent and professional service.
