Refrigerator noise

I had a Sub Zero 550, over/under refrigerator/freezer for 3 years in my previous home. It was wonderful but we sold it along with the house. When we bought this house, I purchased a 601R which is a refrigerator only unit. It's 20 cubic feet of very useful space, runs quietly and has given us very little trouble.
When we had the evaporator replaced a couple of weeks ago, the part was furnished under warranty, the labor came to $450, and I received a check today from Sub Zero for $115. The stub said it was a warranty reimbursement for labor. Considering the age of the unit, I think that was very generous of them.
They also make a 601F freezer to match if you have the space and funds. I have neither so I bought a small GE upright freezer for the garage.

If quality is important to you, there is no alternative. They are not silent but the noise is less obtrusive than most.

Tvad - Your findings concerning Sub Zero warranty are consistent with the terms in my owner's manual.

The big difference between a Sub Zero and more conventional products lies in the fact that the Sub will meet it's original specs long after most other refrigerators have been replaced.

By the way, they claim my refrigerator uses less juice than a 100 watt light bulb.

I bought a Samsung over/under combo fridge/freezer for one of my rentals last year and it seems very nice and user friendly for the $900 and change that I paid. I haven't lived with it at all though so I'm not sure whether or not it gets any points for quiet operation.
