Our Core Specialty
Sub-Zero and Wolf, Done Right
Most kitchens here are built around a Sub-Zero built-in and a Wolf range, and that pairing is what we know best. We read a Sub-Zero's dual sealed systems and diagnostic mode the way the unit intends, and we service Wolf ignition and heating from the actual behavior rather than a code sheet.
- Dual-refrigeration diagnosis on BI, IC, and PRO series
- 424 And 427 wine-column thermistor and seal work
- Wolf dual-fuel, gas range, and wall-oven ignition
- Model-specific parts are selected after diagnosis.
