Los Altos Hills homes are built around custom kitchens — Sub-Zero built-in columns, Wolf ranges, Viking cooktops, Thermador ovens, Miele and Monogram dishwashers fitted into millwork, and more. We've been servicing these setups across the area for over a decade and understand what it takes to work carefully in architect-designed, high-end homes. No shortcuts, no aftermarket parts.
What We Repair
-
Built-in columns, integrated units, wine storage, undercounter drawers, and ice makers. Sub-Zero sealed system work is a specialty — including compressor replacement and refrigerant recharge.
-
Gas, dual-fuel, and induction cooking equipment from Viking, Wolf, Thermador, and BlueStar. Burner issues, ignition failures, temperature inconsistency — diagnosed and repaired same day.
-
Wall ovens, convection systems, steam ovens, and warming drawers. Calibration, heating element replacement, control board repair — all using factory-spec parts.
-
Miele, Bosch, Asko, Cove, and other premium dishwashers. Drainage problems, door latch failures, spray arm issues — fixed without disrupting your kitchen routine.
-
High-end laundry equipment from Miele, Bosch, Electrolux, and Fisher & Paykel. Compact European units and full-size pairs.
-
Sub-Zero recommends annual professional servicing. A $185 maintenance visit — condenser cleaning, seal inspection, temperature calibration — can add years to a $10,000+ appliance's life.
