The previous house I moved from had a Subzero fridge in it from 1990. It was serviced in 2012 and was still running strong when I left. One thing that pleased me was the easy access to a parts catalog and the ability to easily order replacement parts. Some of the tray slides had cracked and I just ordered them online after consulting the catalog. I know the unit cost a fortune in 1990, but decades of service and the ease of ordering parts was certainly nice.
