Called at six in the morning when the fresh food side had climbed to fifty. The tech found the evaporator fan seized behind the back panel, showed me the frost pattern before he touched anything, and had the part on the van. Back down to thirty-eight by the afternoon.

Sub-Zero repair in San Jose and the South Bay
Built-in refrigeration is the one appliance you cannot leave until Monday. We run a 24/7 dispatch line and a route that starts in San Jose, covers the South Bay around it and reaches every other leg of the Bay.
Call dispatch, any hour (669) 338-4601 Someone picks up at any hour. Same-day slots open and close through the day, so the dispatcher will tell you what is actually free when you call.Book online $89 visit · waived when you book the repair

01 What we fix
Six things a Sub-Zero actually breaks in
Almost every call into this line lands in one of these. The point of naming them is that the diagnosis, and therefore the part on the van, is different for each.
01
Refrigerators
Built-in columns and side-by-sides, 500 through 700 series and the newer Designer line. Evaporator fans, defrost circuits, thermistors, control boards, door alignment.
Open 02Freezers
Freezer drawers and full-height freezer columns that will not hold zero, ice over at the back, or frost the drawer front solid.
Open 03Ice makers
No ice, hollow cubes, cloudy ice, an ice bin that welds itself into one block. Module, fill tube, inlet valve and water line, in that order.
Open 04Wine coolers
Single and dual-zone wine columns and under-counter units running warm, running cold, or sweating on the inside of the glass.
Open 05Sealed systems
Compressors, condensers, filter driers and refrigerant leaks. Diagnosed with gauges and an electronic leak detector before anything is cut.
Open 06Everything else
Door gaskets, water lines and shut-offs, condenser cleaning, drain troughs, hinge and cabinet alignment on units that have dropped out of square.
Open 02 Diagnosis
A warm Sub-Zero is usually airflow, not refrigerant
The instinct when a built-in runs warm is to assume the compressor has gone. In practice most warm cabinets come down to one of three things, and only the last one is expensive.
Air cannot move. The condenser sits behind the upper grille and packs with dust and pet hair. Head pressure climbs, the compressor runs longer and longer, and the cabinet drifts up a few degrees at a time. Pulling the grille and cleaning the coil fixes a real share of the calls we take.
Air cannot get past the ice. If the defrost heater or the defrost thermostat has failed, frost builds across the evaporator until the fan is pushing against a wall of ice. The freezer often still reads cold while the fresh food side climbs, which is the classic tell.
There is no refrigerant left. That one is a sealed system job, and we prove it with gauges and a leak detector before anyone talks about opening the system. Read the full not-cooling walkthrough.
03 The visit
What happens after you call
-
The call
We ask for the model number, the temperatures on the display, and what the unit is doing. That is enough to load the van sensibly instead of turning up empty-handed.
-
The slot
The dispatcher tells you which windows are genuinely open today and tomorrow. If nothing is free in your leg of the Bay until the following day, you will hear that on the call rather than after you have waited in.
-
Diagnosis on site
Panels off, temperatures read at the evaporator and in the cabinet, amp draw on the compressor, gauges on the sealed system if the symptoms point that way. The $89 covers this.
-
The quote
Named part, named labour, before anything is fitted. You decide with the number in front of you. Say yes and the $89 comes off the total.
-
The repair
We fit genuine OEM Sub-Zero parts. Compressors, evaporator fans, control boards and gaskets come from the manufacturer, not a pattern-part bin. Most jobs finish the same visit. Boards and compressors are ordered against your serial number, and the second visit is booked before we leave.

04 Coverage
Where the vans go
The South Bay carries the most built-in Sub-Zero work in the region and the route starts in San Jose, but every leg of the Bay is covered from the same dispatch line.
San Jose, district by district
San Jose is where the route starts. The vans are staged on the 280/880 corridor, so a San Jose address is normally the first in line when a same-day slot opens, and the dispatcher can tell you on the call whether one is free today.

What people say after the van has gone
Twenty-year-old 632. Two other companies told me to replace it. These people put gauges on it, found the low-side pressure was fine and the problem was a shorted defrost heater. Fixed for a fraction of what a new one costs.
Booked online at eleven at night and someone still rang me back to confirm. The tech turned up with the model number already looked up and the likely parts on board.
06 Questions
Straight answers
What does the visit cost?
The service call is $89. That pays for the trip and a full diagnosis: model and serial recorded, cabinet and evaporator temperatures read, sealed system checked. If you book the repair, the $89 comes off the bill.
Are you really answering the phone at three in the morning?
Yes. Someone picks up at any hour. Whether a van can be with you that night depends on what is already booked, and the dispatcher will tell you straight rather than promising a slot that does not exist.
Which parts of San Jose do you cover?
All of it. Willow Glen, Rose Garden, Cambrian, Almaden Valley, Evergreen, Silver Creek, Berryessa and every district in between, plus Santa Clara, Campbell, Los Gatos, Saratoga, Cupertino, Milpitas, Sunnyvale next door. The vans are staged on the 280/880 corridor, so San Jose is usually first in line for a same-day slot.
How far across the Bay Area do you go?
All five legs: San Jose and the South Bay, the Peninsula, the East Bay, San Francisco and the North Bay, 61 cities in total. The South Bay is where the vans are staged, so it is usually where a same-day slot opens first.
My unit is over twenty years old. Is it worth repairing?
Often yes. A 500 or 600 series built-in with a healthy sealed system is worth keeping, and most of what fails on them is a fan motor, a defrost heater or a control board. If the leak is inside the cabinet wall the answer changes, and we will say so.
Do you carry parts on the van?
Common failures for the model you give on the phone, yes: evaporator fan motors, defrost heaters and thermistors, door gaskets, ice maker modules and inlet valves. Control boards and compressors are ordered against your serial number.
Tell the dispatcher the model number and what it is doing
It is stamped on a plate inside the fresh-food compartment, usually on the upper left wall or behind the top grille. With the model in hand the van gets loaded with the parts that unit actually fails on, which is the difference between one visit and two.
