Repair across Altadena
Altadena rises gently toward the San Gabriel Mountains, a foothill community of historic Craftsman bungalows, Mediterranean Revival homes and tree lined streets like the famous Christmas Tree Lane. The kitchens here often carry real architectural history, with built in Sub-Zero refrigeration and Wolf ranges fitted into period cabinetry so they read as part of the house rather than something dropped in later. Servicing them means respecting both the appliance and the original millwork around it.
The community is also in the midst of renewal. After the 2025 Eaton Fire, many homeowners rebuilding near the foothills are specifying these same Sub-Zero and Wolf lines for their new kitchens, which puts us at both ends of the spectrum, keeping a beloved older unit alive in a surviving Craftsman and commissioning a freshly installed suite in a rebuilt home. We source parts for legacy and current models alike, so neither generation gets shortchanged.
Foothill summers near Eaton Canyon run warm and dry, and that heat is what tends to expose a tired Sub-Zero condenser or a wine storage unit slipping out of range. We treat those cooling concerns with the urgency they call for, while bringing the same steady hand to a Wolf range that no longer holds an even flame in a kitchen built for gathering.

Local questions
Altadena questions, answered.
Do you service Sub-Zero and Wolf units in Altadena's older foothill homes near Christmas Tree Lane?
Yes. We routinely work on built in Sub-Zero refrigeration and Wolf ranges in vintage Craftsman and hillside properties, including both legacy and current models, and we work carefully around original cabinetry so the repair never disturbs the character of the kitchen.
Can you help with the new Sub-Zero and Wolf appliances in a rebuilt Altadena home?
We can. Many homeowners rebuilding after the Eaton Fire are specifying these premium lines again, and we service those new installations as readily as older units, sourcing genuine parts for both so a freshly fitted kitchen gets correct, factory grade care from the start.
How does the flat diagnostic fee work?
The diagnostic visit is a flat ninety five dollars. The technician identifies the fault and gives you a clear repair price before starting, and if you approve the work, that ninety five dollars is credited toward the repair, so the diagnosis pays for itself.
Are your repairs backed by a warranty?
Yes. Every repair uses genuine Sub-Zero and Wolf parts and carries a three year warranty supported by the manufacturer, which keeps your appliance performing to its original specification whether it is a decades old built in or a newly installed unit.
The Onyx guarantee
The 3 Year Onyx Warranty, parts and labor, in writing.
A $95 diagnostic, waived with your repair, and 24 years on luxury appliances behind every visit.
