Fleming Island — built-ins gone warm
Clay County work, from the Doctors Lake shoreline through Eagle Harbor and Pace Island to the older river lots along Hibernia.
Fleming Island · Clay County
Cold that holds, on this side of the river.
We are an independent repair shop working Sub-Zero refrigeration only — built-ins, integrated columns, undercounters, wine storage and ice makers — across Fleming Island, Clay County and about 40 miles around it.
No emergency surcharges, no sales pitch, and no repair started before you have the estimate in writing. Technicians hold EPA Section 608 certification for refrigerant work.
Fresh food · upper system System one Its own evaporator, its own air, its own failure modes.
Freezer · lower system System two Independent of the first, which is why one side can go warm alone.
Which compartment lost temperature, and whether the other one held, narrows the fault before anyone opens a panel. It is the first question we ask on the phone.
- Diagnostic $80 Flat, and credited toward the repair.
- Labour warranty 90 days From the date of the repair.
- Parts warranty 365 days Genuine OEM parts.

Service
One manufacturer, all of its refrigeration
We do not spread across brands. Everything we carry, everything we have read and everything we have taken apart is Sub-Zero refrigeration.
- Built-ins warm on one side — The full-height built-in units that sit flush with the cabinetry — warm boxes, running fans, frost, water on the floor, doors that stopped sealing.
- Columns warm with the freezer fine — Single-purpose refrigerator, freezer and wine columns that hide completely behind cabinet panels — one box warm, one still cold, and no visible grille to check.
- Drawers cool but not cold — Refrigerator drawers, beverage centres and undercounter freezers built into islands, butler's pantries and lanai kitchens — small boxes in tight, hot cabinets.
- Wine zones drifting warm — Wine units drift before they fail. Uneven zones, a glass door that sweats through August, a fan that runs and runs, and racks that no longer sit true.
- Ice makers that stopped — Standalone ice machines and the ice maker inside a built-in freezer — no ice at all, a bin that never fills, cubes that come out hollow, or water where it should not be.
- Runs constantly, never cold — Refrigerant, compressors, condensers and evaporators — the part of the appliance that cannot be diagnosed from a symptom list and should never be guessed at.
- Doors that will not pull shut — The mechanical half of a refrigerator. Gaskets that have gone hard, hinges that have dropped, closers that stopped closing and custom panels that no longer sit flush.
We do not service heating or air conditioning. No furnaces, no heat pumps, no air handlers, no mini-splits and no ductwork. That is a separate trade with its own licensing, and a call about a house that will not cool belongs with an HVAC contractor rather than with us.
Families covered: built-in refrigeration, integrated column refrigerators and freezers, undercounter refrigeration, wine storage, ice makers.
Price bands
What does a Sub-Zero repair cost here?
Every figure on this site comes out of one file, and this is that file. The visit is a flat fee; the rest is the band a completed repair lands in, parts and labour together.
| Work | Typical range |
|---|---|
| $80 diagnostic visit | $80 |
| Door gasket or seal replacement | $250–$650 |
| Evaporator or condenser fan motor | $250–$600 |
| Defrost heater, thermostat or sensor | $260–$630 |
| Ice maker, water valve or supply line | $250–$620 |
| Electronic control board | $420–$840 |
| Compressor or sealed-system repair | $870–$2,460 |
Ranges, not quotes: the firm figure is written down after the diagnosis and nothing is ordered or billed until you have approved it. On this page the work we describe runs from $80 for the visit to about $2,460 at the top of the band above. The whole book of bands is on the pricing page.
Local
What this county does to a built-in
Northeast Florida runs something in the order of sixty-eight thunderstorm days a year, and the region has sat through multi-day outages after Matthew in 2016, Irma in 2017 and Helene in 2024. Refrigeration does not always fail during the event. A control board that took a surge, or a compressor that was asked to restart against a hot system, can run on for weeks and then quit, which is why we ask what the power did recently even when the call comes long afterwards.
Humidity is the slower load. A door gasket that has taken a set lets warm, wet air into the box, and the first sign is almost never a temperature complaint — it is frost returning on the freezer's back wall, or condensation on the cabinet face around the door.
Then the ordinary things, which are the majority of our work: a condenser packed with dust and pet hair behind the grille, an evaporator fan that has become audible from the next room, a drain line that has closed up and put water under the crisper drawers. None of those needs a new appliance.
Shores
The places we drive to
Eagle Harbor — closers, fans, boards
The largest master-planned community on Fleming Island, and a whole generation of built-in refrigerators that went in with the houses and are still running.
Pace Island — wine and undercounter
A gated community between Doctors Lake and the St. Johns, where most houses have more than one refrigeration appliance and at least one of them lives near water.
Hibernia Plantation — access and openings
Oak-canopy lots with true St. Johns River frontage, houses built one at a time rather than to a plan, and appliances that live under a lot of falling debris.
Doctors Lake — humidity and condensation
Both banks of a tidal arm of the St. Johns — waterfront kitchens, boathouse and garage refrigeration, and the humidity that comes with living on the water.
Orange Park — ice that stopped
The older town on the west side of Doctors Lake, with a housing stock old enough that most of its built-in refrigeration was retrofitted into an existing kitchen.
Waterline
Notes from the van
- Sub-Zero Compressor Noise: Normal or a Fault? — A Sub-Zero refrigerator compressor that hums and cycles on and off is normal; grinding, rattling or a hum that never stops while food warms needs a technician.
- Sub-Zero Wine Cooler Noise, Sound by Sound — A Sub-Zero wine cooler that hums, clicks and whooshes is usually fine; a squealing fan, a grinding rattle or a compressor that keeps restarting needs a look.
- When an Older Built-In Is Worth Repairing — When a fifteen-year-old Sub-Zero built-in is worth repairing and when it is not, and what an independent shop looks at before quoting compressor work.

Asked and answered
Four questions we answer on the phone every week
More of them, in full, on the questions page.
- What does a Sub-Zero repair cost on Fleming Island?
- The visit is $80 and it is credited toward the work. Beyond that, most repairs land in the bands in the table above: a fan, a gasket, a defrost part or a sensor sits in the lower half of the book, an electronic control runs $420–$840, and sealed-system work is the expensive tail at $870–$2,460.
- Which compartment went warm, and why does it matter?
- A built-in carries two sealed systems, one for fresh food and one for the freezer. If one compartment is warm while the other holds, the fault is almost never refrigerant in both. Telling us which side moved narrows the diagnosis before anyone opens a panel, so it is the first thing we ask on the phone.
- Do you repair anything other than Sub-Zero refrigeration?
- No. Built-in units, integrated columns, undercounter drawers, wine storage and ice makers are the whole of the business. We are an independent shop with no manufacturer appointment, and if the appliance is another make we will say so on the phone rather than take the visit and the fee.
- What happens after you diagnose it?
- You get the fault and the figure in writing before anything is ordered or billed, and the $80 comes off that figure if you go ahead. If the repair costs more than the cabinet is worth to you, you will hear that as plainly as the alternative, replacement being $11,600 and upward.

Our refrigerator column was running far longer than it used to. He cleaned a condenser loaded with pollen and oak litter, then rechecked the compartment with a probe instead of reading the front display.
Horace K.2026-09-09
The lower zone would not hold while the upper one was perfect. He found the second fan had failed, so that zone was living on whatever air drifted down, and both read true after the part arrived.
Leander M.2026-04-30
The seal along the hinge side had gone hard and the frame was sweating in the humidity. New gasket, closer adjusted, and the condensation that had been marking the cabinetry has stopped.
