Sub-Zero offers service and repairs through its certified dealer network. A location tool is available on the company's website that finds the closest authorized service center and allows appointments to be booked.
Consumer Reports considers Sub-Zero to be a high-end brand and one of the most expensive refrigeration appliances. However, in performance terms, comparable manufacturers, such as Thermador and Jenn-Air, had overall better performance and lower price tags. The main complaint about Sub-Zero appliances is that they are noisy by comparison to other models. The advantages given were designer styling and brand recognition. For luxury homes, the name recognition is a significant show factor.
