What to have ready before you call or book
| Item | Example | Why it matters |
|---|---|---|
| Model and serial number | one clear rating-plate photo | matches parts and board revisions |
| Two temperatures | fresh-food 49F, freezer 2F | separates airflow from whole-system failure |
| Wide cabinet photo | appliance, floor, trim and grille | plans cabinet-safe access |
| Symptom close-up | alarm, frost line, grille dust, leak or ice | preserves evidence before reset |
| Approval contact | owner or manager if rental | prevents delayed authorization |
Contact FAQ
Questions about the intake process
How do I reach you for Sub-Zero service in Berkeley?
Call (510) 390-9712 or use the Book Online link. There is no custom form — just the phone and external online booking.
What are your service hours?
We take Sub-Zero calls Monday through Saturday, 7:00am to 7:00pm. Call (510) 390-9712 or book online any time and we'll confirm a window.
What should I have ready before calling or booking?
Have the model number, serial number, fresh-food temperature, freezer temperature and a short symptom note ready. If the property is a rental, have owner or manager approval ready before paid work proceeds.
Will service affect a manufacturer warranty?
If your Sub-Zero may still be under the manufacturer's warranty, check the official warranty terms with your model and serial number before approving independent work. Outside warranty, we diagnose and repair with documented readings and OEM parts.
Can a tenant use this contact page?
A tenant can call (510) 390-9712 or use Book Online with temperatures and alarm notes ready, but owner or property-manager approval is usually needed before paid work proceeds.
