Guest-ready facts

Urgency
Start with temperature readings and food or wine risk before discussing parts.
Model proof
Model and serial details reduce wrong-part risk for fans, gaskets, controls, ice maker modules and sealed-system parts.
Temperature log
Fresh-food, freezer and wine-zone readings should include time of day and whether the unit was reset.
What can wait
Stable cosmetic issues, routine maintenance and non-repeating alarms can usually wait for a prepared appointment.
What cannot wait
Food above 40 F, thawing freezer contents, active leaks, electrical smell and pre-event cooling failures need faster triage.

Homeowner, Upper Happy Valley

“The correct serial-matched gasket for our 736TCI arrived on the first try with written part-and-labor terms. $590 total and sealed tight. Upper Happy Valley service was straightforward.”

★★★★★

M.T., Burton Valley

“The evaporator fan for our BI-48SD was genuine and warrantied in writing. $300, recovered to 38 °F, and they explained the lead time up front. Burton Valley.”

★★★★★

Homeowner, Reliez Valley

“The control board on our 690 was special-order; they quoted $780, gave a written warranty and verified operation before leaving. Honest about the wait. Reliez Valley.”

Warranty terms

Clear, written warranty terms

Warranty terms are written on approved work and kept consistent between the estimate and the invoice, covering both the part and the labor performed. You always know what is covered before the repair begins.

Part lead time can matter for pre-event failures. Having the model and serial ready helps identify whether the part path is routine, special-order or not economical.

Lafayette route logic

Local service notes tied to timing and access

Happy Valley / Upper Happy Valley

Hillside access, larger built-in kitchens and pre-event scheduling make model-tag details and cabinet access notes useful before the route is set.

Reliez Valley

Afternoon heat, dust and route timing can change whether same-day triage or next-day prepared service is more realistic.

Burton Valley

Family kitchens often need practical freezer, ice maker and gasket checks that protect floors and panels during routine service.

Trail neighborhood

Homes near the Lafayette-Moraga Trail benefit from clear parking, gate and access notes so tools reach the built-in safely.

Parts and Warranty FAQ

Do you use genuine Sub-Zero parts?

Yes. Parts are matched to your model and serial number, and the exact part source and warranty terms are stated on the estimate and invoice.

Why do parts need the serial number?

The serial number can change part revisions, compatibility and warranty language. It reduces wrong-part risk for gaskets, boards, fans, sensors and ice maker parts.

Can parts be quoted before the visit?

A planning range can be discussed before the visit, but final parts are matched after the model, symptom and access evidence are verified.

What if a part is not available?

The repair-versus-replace decision includes part availability, lead time, age, cabinet disruption and whether temporary stabilization is possible.

Are warranty terms provided in writing?

Yes. Warranty terms for the part and the labor are written on the approved estimate and the invoice.

Can a second visit be prevented?

Often. Having the model, serial, symptoms and temperature history ready before the visit reduces wrong-route and wrong-part risk.
