Easy to book online for our Sub-Zero 690. They were straightforward about having the model tag and temps ready; the $145 diagnostic was exactly as quoted. Painless.

The visit confirms evidence before quoting a fan, gasket, valve, board, sealed-system path, or cabinet access.
Step by step
Before contact
A strong booking note saves time because Sub-Zero symptoms often overlap. For sealed-system suspicion, include whether both compartments are warm, whether the compressor seems to run constantly, and whether the condenser area was recently cleaned. For cabinet-safe access, have appliance, floor, toe-kick, panel reveal, and tight-island or doorway details ready if scheduling asks.
If the issue is a condenser coil packed with dust or pet hair, do not try to dismantle the grille. Call or book online and describe pets, dust load, and recent heat-wave behavior. If the problem is ice maker or water line related, describe cube shape, harvest timing, filter age, leak location, and whether the water shutoff is accessible. For a wine column, include actual probe readings if you have them, display readings, alarm details, and which zone is drifting.
The quote should come after model and serial confirmation, not from a generic menu. The visit should explain which evidence supports the diagnosis, whether an OEM fan, gasket, valve, thermistor, control board, or sealed-system path is being considered, and what verification will happen after the repair.

Called with a cooling emergency on our Sub-Zero 632 and got real help, not a runaround. Diagnostic was $150, scheduled the same week. Simple and clear.

Responsive from the first call. They booked our Sub-Zero 648 gasket repair ($520) for the next morning. Exactly what you want when the fridge is down.

Questions from this page
Use the call button or the external online booking link published on this page.
Call or book online first. If scheduling asks for details, have the model and serial number, fresh-food temperature, freezer temperature, alarm details, cabinet access notes, and symptom notes ready. For wine storage, include display and independent probe readings by zone if available.
Cabinet-safe service starts with trim clearance, floor protection, water and electrical slack, panel reveal and whether the symptom can be diagnosed from front access. A pull should be planned from evidence, not assumed by phone.
No. Compressor, board and sealed-system language should follow airflow, fan, seal, sensor, temperature and cabinet-access evidence. A phone guess is especially risky on a built-in Sub-Zero refrigerator.

The diagnostic is $110–$175 and covers a full cold-side inspection, model and serial check, and temperature and airflow readings. It is credited toward the repair when you proceed. Have the model/serial photo and current temperatures ready to speed up scheduling.
