Is a Sub-Zero Refrigerator Worth the Money?

Is the extra expense worth it? If food preservation is important, it very well might be. Those who follow an organic diet complete with plenty of fruits and vegetables will appreciate having a refrigerator that keeps that produce fresh longer. Design is also a huge plus with Sub-Zero refrigerators, since they are available in a wider variety of sizes than their standard counterparts. These refrigerators are able fit seamlessly into the cabinetry of high-end kitchens and almost “disappear”. All in all there are several reasons we tend to believe these units are our worth the price, and here are some of the main reasons.

Why we say YES.

1) Food Preservation—save $1500 on food you won’t throw away

Sub-Zero prides itself on its ability to preserve food far longer than others. They say on average, a family can save $1500 per year on food they didn’t have to throw away due to the food preservation capabilities of these units. In order to keep food fresh you can’t just keep food cold, you also need precise control of the temperature, humidity and also the ability to purify the air in which the food is being stored. We will dive a bit deeper into several of the key features that help to set Sub-Zero apart from the rest.

Dual refrigeration

Two separate sealed systems are used to control the refrigerator and freezer. This allows the separate compartments to stay at optimal humidity levels and also prevent flavor transfer.

Microprocessor controlled system

This allows the units to hold a temperature that is far more consistent than most. In fact Sub-Zero maintains a temperature within one degree of the set temperature at all times during normal use. This is very impressive when you consider that other refrigerators see temperature swings of up to 14 degrees. Simply put, consistent temperature will allow food to stay fresh far longer.

Vacuum seal
Sub-Zero has a patented vacuum door seal system. This means that all four sides on the unit vacuum seal when you close the door in order to maintain optimal temperature.

Air purification

These units contain an antimicrobial air purification system that automatically scrubs the air every 20 minutes. Many fresh foods emit ethylene gas which causes other foods to spoil much faster. By filtering out these gases, along with bacteria and mold spores that are found on many fresh produce, your food will last far longer.

2) Quality/Longevity

The quality standards this company holds are second to none. The raw materials used are the best. They simply do not compromise when releasing new units and the products are designed and tested to last 20 years. They also test every single unit in the factory before it is put in its box.

There is no question that this company has arguably one of the highest levels of service and customer support in the industry. Besides delivering a world class product, if something should go wrong you can rest assured that it will be taken care of quickly and efficiently. They also have one of the best factory warranties. You receive a full two-year warranty which is all inclusive. You then carry a full five years on the sealed system, which is essentially the heart of the unit, including compressors, condensers, evaporators, driers and even tubing. You then continue to be covered on the sealed system with a limited 12-year warranty.

3) Flexibility

No other brand of refrigerator offers as many models and configurations as Sub-Zero. If design and layout are important to you, this needs to be considered.

4) Home Resale Value

Sub-Zero has more brand recognition than any other appliance in the industry. If a kitchen has a Sub-Zero it will almost always be mentioned in real-estate listings because that can become a deciding factor on the purchase. People know that a kitchen can be one of the most expensive renovations of any home so as soon as they see the name Sub-Zero, they automatically assume quality across the board.

The Models

There are three types of Sub-Zero refrigerators on the market, each with its own unique benefits.

Built-In (BI)


Considered the classic look for Sub-Zero refrigerators, BI units were the original concept for this type of refrigerator. The doors on BI Sub-Zero refrigerators protrude slightly from the cabinet surface, but they can be made flush with an inset installation. However, in doing so, it’s important to make sure you leave enough room for the doors to open. BI units come in four configurations: column, French door, over-and-under, and side-by-side.



More than 30 different configuration options make this popular with homeowners who want control over their kitchen design. Since there are no exposed hinges or grills, you can seamlessly flush mount this unit without leaving space around the perimeter of the appliance. This allows you to make an Integrated Sub-Zero disappear into your cabinetry. There are two types of integrated models: column and over-and-under.

Pro 48


In a league of its own, Pro 48 is the top-of-the-line model for Sub-Zero refrigerators. The company often refers to this line as an 800-pound monument to food preservation. The look of the Pro 48 is reminiscent of what you’d see in a restaurant kitchen, but its beautiful design makes it the perfect fit for your home. In addition to its attractive design, the Pro 48 has triple evaporators, with each serving as a separate control for the freezer, refrigerator, and refrigerator drawers.
