What we repair
Sub-Zero refrigeration only. Every visit starts with the same $80 flat diagnostic and a written estimate.
We are an independent company servicing one manufacturer. That is a deliberate limit rather than a gap: knowing one line of equipment well beats knowing six badly, and it means the service positions, the access constraints and the parts on the van already match the appliance in the opening. Whichever of these pages brought you here, the visit runs the same 6 stages in the same order.
- Built-in refrigeration
Sub-Zero Built-In Warm on the Food Side, Nocatee
Two refrigeration circuits in one cabinet, a condenser working against Florida heat, and a door heavy enough to change its own geometry.
- Sealed systems
Sub-Zero Compressor Runs and Nothing Gets Cold
Compressor, condenser, evaporator and refrigerant faults — measured last, because five cheaper stages can each make a healthy circuit look sick.
- Integrated columns
Sub-Zero Column Door Ajar Alarm at Night, Nocatee
Panel-hung doors, hinge and closer wear, and two cabinets side by side that share nothing but the joinery they are set into.
- Undercounter units
Sub-Zero Undercounter Drawer Running Warm, Nocatee
Toe-kick airflow, island heat, drawer runners and a drain path that ends under the compressor — the faults that come with putting refrigeration in a base cabinet.
- Wine storage
Sub-Zero Wine Zones Drifting Together, Nocatee
No water connection, no ice, no defrost drama — and four faults that quietly put a dual-zone cabinet out of specification without ever raising an alarm.
- Ice makers
Sub-Zero Ice Maker Making Small Hollow Cubes
Cube size is a symptom, not a diagnosis. Fill volume is measured with a vessel and a stopwatch, and the freezer compartment is checked before any valve is quoted.
- Filters and dispensers
Sub-Zero Dispenser Flow Slowing Week by Week
A cartridge is rated in gallons, not months. Where flow has dropped, the restriction is found by measurement — filter, valve, supply or dispenser line.
Every one of these visits starts the same way: $80 flat, measurements before opinions, and a written estimate you approve before a part is ordered. Completed work carries 90 days on labor and 365 days on parts. See warranty terms or the common questions.
What does Sub-Zero refrigeration repair cost here?
$80 flat to diagnose, credited toward the repair once you approve it. Completed work on this page has landed between $240 and $2,270, parts and labor together. The firm figure is written down after the diagnosis, not before it.

| Electronic control board | $420–$780 |
| Compressor or sealed-system repair | $910–$2,270 |
Ranges are what this work has cost, not a quote. A range moves with the part version the serial number calls for and with what the cabinet turns out to need. The whole table is on the pricing page.
What does Sub-Zero refrigeration repair cost here?
$80 flat to diagnose, credited toward the work. Completed repairs in this category have run $240 to $2,270, parts and labor together. The band your cabinet lands in is written into the estimate before anything is ordered.
Does the 50% rule apply to a built-in?
Rarely on a full-size cabinet. The dearest repair in the book, $2,270, is about 20% of the cheapest comparable replacement at $11,600, and panels and cabinetry sit on top of that figure. On a wine or undercounter unit it becomes a real test.
When is the cabinet not worth repairing?
When the part is discontinued, when the lead time is longer than you can live with, or when the figure is a large fraction of a replacement. A sealed-system repair runs $910–$2,270, and the estimate says plainly when that is the wrong side of the comparison.
