Two previous cvompanies ahd left me hanging regarding this fridge and a replacement is around $4000. Darren at Celtic showed up when he said and worked diligently on the problem. He informed me that this would be a true process to determine the problem. He kept me aware of the process and that he was pulling in the knowledge and experience of others. Darren was relentless with the time he put in and assured me that he would not do me wrong at the end of the day re: the bill. Well, he fixed the problem where others gave up and he kept his word re the bill. VERY fair considering the hours he actually put into this. I would hire him for any job in the future.
