While the average refrigerator may have a lifespan of eight years or less, Sub-Zero refrigerators can last for decades. They can experience problems like any other appliance, but a combination of built-in reliability and regular repair and maintenance will help them live up to their potential. Unlike other double-door refrigerators that might cost a couple of thousand dollars, Sub-Zero models start over $7,000, which makes regular care necessary to protect your investment.

What’s Special About Sub-Zero

What makes this brand of refrigerator so pricey are the many built-in features that set it apart from other refrigerators.

Dual compressors: Sub-Zero refrigerators have separate compressors for the refrigerator and the freezer, reducing the load on each compressor. The result is that foods in each unit area stay at the ideal temperature, better than possible, when one compressor controls the freezer and the refrigerator. The result is less food loss. According to kitchen designer Mick deGuillio, “Fresh food lasts 40 to 50 percent longer in a Sub-Zero than other models and frozen for at least 200 to 300 percent longer.”

Dedicated units: Most homeowners prefer combination refrigerator-freezers, but Sub Zero models are available in all-refrigerator or all-freezer models. In addition to the regular-sized units, you can buy a modular refrigerator or freezer drawers that can be installed below cabinets for a custom setup.

Patented air filtration system: Produce and other foods give off ethylene gas which can lead to spoiling, wilting, or discoloration. The filtration system in a Sub-Zero prevents this while also removing bacteria, mold, and viruses and reducing odors.

Better sealing on the doors: Heavy insulation, tight hinges, magnetic gaskets, and triple-pane glass on Crestor models keep food fresher by creating a vacuum that preserves the food.

Microprocessor control system: Adding to the effects offered by the dual compressors, these refrigerators have microprocessor control to ensure optimum temperatures in each part of the unit. You can also adjust the lighting, adaptive defrost, and cooling fan and be notified if someone leaves the door or drawer open.

Keeping Your Sub-Zero Working Efficiently

To get the most from your refrigerator, it is important to ensure that you perform regular maintenance and quickly call for service when needed.

Keeping the compressors working correctly to achieve these impressive results requires keeping them clean. Unlike a normal refrigerator that has the compressors at the back, the Sub Zero has them mounted at the top or bottom of the unit for easier access. While most homeowners can manage this maintenance, a professional can do the cleaning if you prefer.
