Excellent service! The lights in my refrigerator had shorted out, fusing one bulb into the socket. Hemi's diagnosed the problem and scheduled a time to replace the part. When I had to reschedule, I was pleased to find my request handled matter-of-factly and courteously. Upon arriving with the replacement part, Hemi realized that the manufacturer had not shipped everything needed and customized a part from another manufacturer. The customized replacement part includes a thermostat--something that might have prevented the original problem. Very happy with the service, expertise, and professionality.
