What's the drive time to Portola Valley and how do you schedule it?

We put Portola Valley on the same Peninsula route as Hillsborough. From San Ramon, figure 50 to 60 minutes taking I-680 south to either 92 or 280. We give you a written arrival time when the appointment is booked, not a loose window.

Do you carry Sub-Zero parts for the units common in Portola Valley?

Condenser and evaporator fan motors, standard gaskets, and the rebuilt 736TCI dispenser board are on the truck. Sealed-system parts like compressors and evaporators get ordered per job because they're unit-specific.

Sub-Zero in Portola Valley

Sub-Zero in Portola Valley kitchens.

Portola Valley homes in 94028, spread across wooded acreage off Alpine Road and Portola Road, run Sub-Zero columns and built-in refrigeration in kitchens finished with panel-ready everything, and the same setup shows up in the mid-century modern houses in the Ladera-adjacent pockets. This is a wildfire-aware town, and the PG&E public-safety shutoffs that come with fire season put these sealed units through repeated power cuts and restarts that a house on the flats never sees.

We see the 736TCI and 736TC dispenser control board fail here too, and on top of the ordinary age wear, the repeated hard power cycling from PSPS events stresses the board further. Sub-Zero discontinued it at the factory, so we source a rebuilt unit through refurbishers we trust, but only after we confirm the board itself is dead. We provide a written repair estimate after the on-site diagnosis and before any work starts.

What the work looks like

A built-in sealed-system leak repair.

Nitrogen pressure and a soap-bubble test on a built-in fridge line set. We map every leak source before we braze.

The corroded copper up close. After fifteen-plus years this is why a real fix rebuilds the sealed run, so you do not pay the labor twice.

Common repairs we do

What we close on the truck.

Sealed-system service, column and built-in units. Compressor or evaporator-side leak. Recovery, weigh-in on the new charge, and a 24-hour vacuum pull before we sign off.
Condenser coil clean and fan-motor replacement. On Classic 36 and 48 inch units, a blocked grille behind the panel front chokes the coil and the fan works overtime. Cleaning and a fan swap fixes it without touching the sealed side.
736TCI / 736TC dispenser control board. Factory-discontinued, sourced rebuilt. We confirm the actual failure before ordering, especially on units that have been through repeated PSPS power cycling.
Designer Series column door alignment. Hinge cartridge wear lets the door sag and breaks the gasket seal. We swap the hinge cartridge and recover the seal so the column stops running long.
