Kampen is the only Factory authorized Sub Zero factory repair service and as a result have a monopoly and as such are expensive.
A competent technician was dispatched at a cost just shy oy $275 to diagnose the issue with our Sub Zero under counter wine cooler. The good news was that the parts were still within the 12 year warranty period + extra for the labour.
I received a quote of $1356.00 flat rate for the labour to repair including refigerant. After researching a replacement unit at a cost of around $6k, I reluctantly decided to proceed with the repair.
Kampen charge $35/15 minutes for labour. The extremeley competant technician replaced the coils and refrigerant in 2 hours, that included a new gasket on my Sub Zero refrigerator. The fixed quote for labour was $875. This equates to 6.25 hours. Assuming travel time of 1 hour each way, the job if quoted on an hourly basis would have been $560 (with travel at $140/hour as well).
When challenged they indicated that they charge a fixed rate as some repairs are more complicated than others. While their service was excellent, they are extremely expensive and hence my rating, given that I did not have a choice in selecting anoter Factory Authorized Repair facaility and given that their technician diagnosed the issue at an additional charge and knew the exact problem and I am sure had done a similar repairs previously.
