Built-In Refrigerator Repair
Appliance Repair Jax is an independent appliance service company. We are not affiliated with, authorized by, or endorsed by Sub-Zero Group, Inc., or any other manufacturer named on this site. All brand names, model numbers and trademarks are the property of their respective owners and are used here only to identify the appliances we service.
Independent specialists · Not a factory service center
A Sub-Zero is not an appliance you replace. It is millwork with two sealed systems inside it, built to run for twenty-five years. We keep them running — and we do the sealed-system work most shops will not touch.
38°F fresh food 0°F freezer Dual refrigeration EPA 608

The one we are known for
Every full-size Sub-Zero has two completely separate sealed systems — two compressors, two evaporators. The fresh-food side is kept cool and moist; the freezer is kept frigid and dry.
That is why a Sub-Zero can sit at 55°F on the refrigerator side while the freezer holds a perfect 0°F. On any ordinary refrigerator that would be a contradiction. On a Sub-Zero it is the normal presentation of a specific failure, and it tells a technician which of the two systems to open. A shop that talks about the compressor has never worked on one.
It also explains why these units are worth repairing. A replacement runs into five figures once the cabinetry is reworked around it. A sealed-system repair does not.
Series we work on
The old names are still the ones people use. “Built-In” became Classic, and “Integrated” became Designer — but nearly all the service work is in the legacy units, and we keep both vocabularies because our customers do.
What we repair
The appliances that were installed into the cabinetry rather than pushed into a gap — where a replacement means a carpenter as well as a delivery truck.

How a service call works
The data plate is behind the door or inside the cabinet. That number tells us the series, the platform, and which parts fit before we leave the shop.
With a call ahead, floor protection and shoe covers. Most of St. Johns and south Duval gets a same-day or next-day slot.
The $129 diagnostic covers a full diagnosis. You see parts and labor in writing, and nothing is opened up until you approve it.
Genuine OEM parts, 90 days on our labor and 365 days on parts. If the same fault comes back, so do we.

Where we work
St. Johns County, all of Duval, and the populated parts of Clay. We publish drive times, not straight-line distances — with this many bridges the two are not close.
St. Johns County 2 miles
Our shop sits at 164 Johns Glen Drive in Fruit Cove, so 32259 is a same-ZIP call for built-in refrigeration, ranges, dishwashers and wine storage.
St. Johns County 2 miles
A 4,100-acre community with roughly 45 neighborhoods built from the 1990s to buildout around 2022, which means three separate generations of built-in refrigeration on the same streets.
Duval County 5 miles
Duval County's stretch of the St. Johns south bank, running from 1970s subdivisions on generous lots up to gated riverfront estates off Mandarin Road.
St. Johns County 16 miles
Nocatee is 15.9 miles and about 28 minutes from our Fruit Cove base. It sits in St. Johns County, not Duval, and its earliest built-ins are past fifteen years old.
St. Johns County 23 miles
Ponte Vedra Beach is 23 road miles from Fruit Cove, in St. Johns County. One ZIP holds club-era cottages, 1990s country club kitchens and current custom rebuilds.
St. Johns County 15 miles
World Golf Village is 15.3 miles and about 27 minutes from Fruit Cove. It is inland, so storm damage and a twenty-year spread of platforms matter more than salt.
Before you call anyone
Some of what goes wrong on a built-in is genuinely a five-minute fix, and we would rather you knew that. These are written by the people who do the work.
Installation Pro only
A built-in is cabinetry, not an appliance you roll out. What a service pull really involves, what gets damaged when it is rushed, and how to prepare for one.
Maintenance
What to do before, during and after a multi-day outage: food safety timings, the restart order for built-in refrigeration, and the mistakes that cost a board.
Troubleshooting
USDA food safety windows, the order to move things in, and the seven checks worth making before you call anyone. Written for the morning you find it warm.
Customer feedback
Rated 4.8 out of 5 across 72 customer reviews. Three of them, picked without a thumb on the scale.
Corinne D.Mar 4, 2026
The brewer stopped mid cycle and flashed for water with a full tank. He found the flow meter blocked with scale off our hard supply, descaled the circuit and rebuilt the brew unit seals. It has pulled a clean cup every morning since.
Verity S.Jan 22, 2026
The oven side of our range was running well under the dial and everything came out pale. He recalibrated it against a probe, then found the door seal had shrunk at one corner and replaced it. Baking is even again.
Grant W.Apr 16, 2026
Water was pooling under the crisper every few days. The drain trough had frozen over, which he thawed before fitting the correct heat clip so it runs away properly. There are no more towels living under that drawer.
Straight answers
Most of our service area gets a same-day or next-day appointment. We work in two-hour arrival windows and call ahead when the technician is on the way. Fruit Cove, Mandarin, Bartram Park and Julington Creek are usually same day; Ponte Vedra, St. Augustine and the Beaches are typically next day.
A flat $129 diagnostic fee covers the trip and a full diagnosis, and it is credited toward the repair when you approve the work. You get the price in writing before anything is opened up. We do not quote repairs over the phone, because a guess is worth nothing to either of us.
No, and we will never say otherwise. We are an independent appliance repair company with no affiliation to Sub-Zero Group, Inc. Factory Certified Service is a separate, invite-only manufacturer program, and you can check who holds it in your ZIP code at subzero-wolf.com/locator or by calling Sub-Zero Customer Care.
Yes. Our technicians hold EPA Section 608 certification, which federal law requires to open a sealed refrigeration system, and we perform compressor, evaporator, drier and tubing repairs in the home. Many companies will replace a fan or a board and then declare a unit unrepairable, because sealed-system work is the line they cannot cross.
Roughly forty miles by road from our base in Fruit Cove. That covers St. Johns County, all of Duval, and the populated parts of Clay County, including Ponte Vedra Beach, Nocatee, St. Augustine, the Beaches, Orange Park and Fleming Island.
