Are you a Sub-Zero authorized dealer?

No. We service Sub-Zero built-ins as an independent shop, so we'll tell you straight what's wrong and what it costs. Sealed-system work is done in-house under EPA #1279674151528.

How quickly can you get to a Hillsborough home?

We dispatch from San Ramon, across the San Mateo Bridge and up 280, usually under an hour off-peak. Open 7AM to 7PM, seven days. Call (925) 999-4095.

Is it worth repairing instead of replacing?

Almost always. A Sub-Zero built-in is made to run twenty years and made to be fixed, and swapping one usually means a cabinetry refit too. We give you a written quote and a straight repair-or-replace read before anything else happens.

Sub-Zero in Hillsborough

Sub-Zero refrigeration in Hillsborough.

Hillsborough doesn't have a commercial district. The town's zoned entirely residential, and that means the refrigeration work here is almost all in the homes. Sub-Zero built-ins are everywhere behind these gates, full-size columns, integrated drawers, and dedicated wine storage in kitchens that were often designed around the appliance layout.

We service all of it as an independent shop. No Sub-Zero factory authorization, just an honest diagnosis before anyone opens a panel.

The diagnostic is $99 and it is credited toward the repair. We carry gauges, a micron gauge, and a recovery machine on the truck.

Common repairs we do

What we close on the truck.

One side running warm on dual-refrigeration units. Sub-Zero runs the fresh-food and freezer sections on separate sealed systems, so it's common for one side to drift warm while the other holds fine. That points to a slow leak on that circuit. We diagnose it properly, then recover, evacuate, and weigh in a fresh charge under EPA #1279674151528.
Condenser fan and coil fouling on Classic and Designer units. The condenser sits behind the toe grille or up top depending on the model, and it packs with dust over a few years, especially if cabinetry blocks proper airflow. We pull the unit, clean the coil, and check the fan bearing before it seizes and takes the compressor with it.
Wine column temperature drift. A lot of Hillsborough kitchens run dedicated Sub-Zero wine storage, and the common complaint is a zone that won't hold its set point. We check the door seal, the evaporator fan, and the sensor calibration, and the sealed system if those check out clean.
