Centigrade is an outstanding company. When we reached out to them, they first attempted to diagnose the issue over the phone to potentially save us the cost of a service call. However, after following their steps, it became clear we needed a technician. Ryne was the technician who came to assist us, and he was simply wonderful. Their prices are very competitive, and their honesty stands out. I highly recommend Centigrade for any medical refrigeration needs.
