When my unit was tested I was told the capacitor needed to be replaced. I told the tech he replaced it less than a year ago. He said it could be faulty or the unit could cause it to malfunction and he would replace it at no cost since it was still under warranty. My invoice does not show that it was replaced. I would prefer that you send Sean for my next appointment as I have had a good experience with him on previous visits. I am not sure I have confidence in the newer employee.
