About Sub-Zero
Sub-Zero Freezer Company was founded in 1943 in Madison, Wisconsin by Westye Bakke, who invented the first under-counter residential refrigerator. Bakke's insight — that the freezer needed to be separated from the refrigerator with its own compressor — led to the dual-compressor design that keeps food fresh far longer than standard single-compressor units. Sub-Zero introduced the first built-in refrigerator in 1945, defining an entirely new product category. The company remains privately held and family-owned to this day, with manufacturing in Madison, Wisconsin. Sub-Zero appliances are widely considered the highest quality refrigeration products available for residential use, with service lives that often exceed 25 years.
