Absolutely awful! After spending very little time looking at my refrigerator, he pronounced it to be a closed system issue and that it would most likely be too expensive to fix. However, if I wanted to know exactly what was wrong with it and whether or not it truly would be too expensive he would charge me an extra $150 just to diagnose it. When I told him that I thought the $75 service fee was for a diagnosis he said, "no that's just to get me to walk through the door." Since then, I have spoken with several other repair companies that have assured me that the service fee is for a diagnosis.
