  • “Best service in the Valley. Fast and professional — they diagnosed my Sub-Zero defrost fault the same day and the $89 came right off the repair.”

    Alexander G. — Menlo Park, CA

  • “My Wolf range was clicking but not lighting. Genuine OEM igniter, fixed in one visit, and backed by the 365-day labor warranty. Spotless work.”

    Catherine W. — Palo Alto, CA

  • “BI-48 ice maker stopped cold. The technician arrived in a tight window, replaced the module, and left the kitchen cleaner than he found it.”

    Robert H. — Pacific Heights, San Francisco

    Diane K. — Tiburon, CA

Q & A

Frequently Asked Questions

How quickly can you arrive?
We have local technicians stationed across the Bay Area, so we offer same-day service in most areas when you call before noon. Evening and weekend slots are available for urgent refrigeration faults that put food at risk.
How much does a diagnosis cost?
The service call is $89, and it is waived — credited in full against your repair — when you book the work. The technician reads any error code, tests the implicated parts, and gives you a written quote before any work begins.
Do you use genuine OEM parts?
Yes. We install factory-certified, genuine OEM parts for Sub-Zero, Wolf, Viking and Cove, and our work follows manufacturer service specifications. That is why we can back every repair with a full 365-day labor warranty.
What is your warranty?
Every repair carries a 365-day warranty on all labor. If the same issue returns within a year, we come back and fix it at no additional cost. Genuine OEM parts also carry their own manufacturer coverage.
Which brands and appliances do you repair?
We specialize in luxury and built-in appliances: Sub-Zero refrigeration, freezers and wine units; Wolf ranges, ovens and cooktops; Viking pro ranges and refrigeration; and Cove dishwashers. Focusing on these brands keeps our expertise deep, not generic.
Are you an authorized Sub-Zero service center?
No — we are an independent specialist, not affiliated with Sub-Zero Group, Inc. or Viking Range, LLC. We install factory-certified, genuine OEM parts and follow manufacturer procedures, often with faster scheduling than an authorized center. See our independent-vs-authorized guide for the honest difference.
Which areas of the Bay Area do you serve?
We cover San Francisco, the Peninsula, Silicon Valley, the South Bay, the East Bay and Marin County — based out of Burlingame, with local arrival windows across all six regions. Check the service-areas page for your city.
What should I have ready before the visit?
Have your model and serial number (usually on a plate inside the door or behind a drawer), a photo of any error code on the panel, and a note of the symptom. That lets us bring the right OEM parts and often resolve the issue in a single visit.
