Your Sub Zero 500 or 600 model has served your family well over the years. The Sub Zero 500 series was introduced in 1987 while the 600 series came later in 1996. Even high-end manufacturers like Sub Zero have a product lifespan where they work well, and then start to break down more and more often. These award-winning models typically last for about 18 to 20 years. There’s a good chance that your Sub Zero 500 or 600 series model may be going towards the end of its normal life cycle. It can be beneficial to move forward with a new refrigerator.

Why You May Hesitate

There are a few reasons why you may hesitate to replace your Sub Zero 500 or 600 series refrigerator, especially if you’re not noticing any problems with it per se.

  • One of the first reasons people wait to replace their refrigerator because they feel if it’s not broke, don’t fix it. It can be hard to pay out money for a new item when the old one seems to be doing its job. However, even if your old refrigerator appears to be working as it should, it may be close to breaking down or could be costing more money to run than a newer more energy efficient model would.
  • That also goes hand-in-hand with the pricing. A high-quality appliance being replaced can be an expense you weren’t expecting, but in the long run, it can often be a cheaper option. You won’t have to worry about costly repairs, losing a whole refrigerator and freezer full of food when the old one breaks down or paying more on your electric bill for an old refrigerator that isn’t energy efficient compared to modern appliances.
  • Others may hesitate because the refrigerator is built into the cabinets in the kitchen, and it seems like it may be a real hassle to have to replace it. It will take some expertise to be able to take out the old unit and have the new one installed in the same spot without being able to tell that it wasn’t the same refrigerator as before.

Benefits of Upgrading

It can be easy to think that any new refrigerator is going to be the same as your old refrigerator, but that’s not the case. There are some amazing upgrades to the Sub Zero refrigerator line that can make upgrading to a new refrigerator a great idea.

  • They are more energy efficient and fall under Energy Star qualifications compared to older models.
  • You’ll notice that the newer refrigerators are quieter compared to your old one due to upgrades in the compressor. Food will last longer and taste better thanks to improvements made in newer refrigerators. For instance, there are added air purifiers that will help with filtering out things like odors, ethylene, bacteria, mold, and viruses. As ethylene makes your food ripen and over-ripen it when the food is exposed to it, having it filtered out will give you more time with your fresh produce at its optimum taste and texture.
  • There are also dual compressors in most newer models that will help with odor transfer and stop freezer burn from happening. A newer model will also provide you with better control over the temperature of the refrigerator.    

Matching Your Model With a New Model
