Our Sub-Zero freezer started making excessive noise over the last few years (erratic defroster fan motor). I finally looked for a repair company, and based in part on Yahoo reviews, I decided to try Hi-Tech appliance repair. I was not disappointed. Professional, prompt, courteous, and a very reasonable cost. When the technician came out for the initial service call, OF COURSE the freezer performed flawlessly and had only factory new noise levels. The tech waited patiently for 45 minutes, and despite no excessive noise, believed what I told him, narrowed the problem down to the only issue it could be, and gave me several options with no pressure. (I decided to replace the fan motor--and the issue seems to be resolved.)
