Built-in refrigerators and freezers
Cabinet not holding temperature, frost building on the back wall, a compartment that runs warm while the other side is fine, or a unit that runs without ever cycling off.
Mandarin · Jacksonville, FL · ZIP 32223 / 32257 / 32258
Independent Sub-Zero refrigeration service, on this side of the river.
Loretto Cold Service works on one product line and one only: Sub-Zero built-in refrigeration, wine storage and ice machines, in Mandarin and the neighbourhoods along the St. Johns.
$80 flat diagnostic, credited toward the repair · 90 days on labour, 365 days on parts.
What we work on
Every visit is the same product line, so the second and third of these faults look familiar rather than new. If your symptom is not listed here, describe it on the phone in your own words — you do not need the right vocabulary for it.
Integrated columns and undercounter units
Doors that no longer sit flush with the cabinetry, condensation along the gasket line, drawers that ice up, and control panels that stop responding.
Wine storage
Zones drifting apart, a compartment sitting several degrees above its setting, humidity that will not hold, and fans that have become audible from the next room.
Ice machines and ice makers
Thin or hollow cubes, a mould that fills but never harvests, a fill valve that has stopped metering cleanly, and slow production that gets worse through the summer.
Where the list stops
What this shop does not touch
Worth writing down, because the phone rings with it. This is a cold shop. Sub-Zero built-in refrigerators and freezers, integrated columns, undercounter units, refrigerator and freezer drawers, wine storage and ice makers — that is the entire list, and it is the entire list because it is the whole of what the manufacturer builds.
We do not service heating, furnaces or heat pumps. We do not service air conditioning, air handlers, thermostats or ductwork, and we do not install any of it. If the house is uncomfortable and the refrigerator is behaving itself, the number you want belongs to a licensed heating and air-conditioning contractor in Jacksonville rather than to this shop. Ovens, cooktops, dishwashers and laundry are out for the same reason the cooling is in: no Sub-Zero cooking appliance exists, and nothing else in the kitchen is worked on here.
Local conditions
Shade, storms and what they do to a built-in
Mandarin's live oaks are the reason people move here and the reason condensers foul. On a Sub-Zero built-in the condenser sits at the top of the cabinet, behind the grille above the doors, drawing room air through a narrow slot at head height. Whatever is suspended in the air of the room ends up in those fins — a heavy spring pollen load, fine leaf litter, ordinary household dust, and pet hair if there is a dog in the house. The appliance never complains about it. It runs longer to shed the same heat, holds its temperature, costs more to run, and then one hot afternoon it cannot keep up.
Power is the second condition. Duval County runs on the order of sixty-eight thunderstorm days in a typical year, and this city has been through multi-day outages after hurricanes more than once in the last decade. What we see afterwards is undramatic and consistent: a cluster of calls about displays, settings and controls behaving oddly in the weeks following a bad storm week. If a cabinet started acting strangely after the power blinked, say so on the phone. It narrows the diagnosis genuinely, and it sometimes turns a board replacement into a reset and a check of the circuit.
The third is the housing itself. Mandarin runs mostly to 1970s through 1990s subdivisions on generous lots, with older riverfront homes along Mandarin Road, and most of those kitchens have been remodelled at least once. The appliance is usually newer than the opening it sits in, newer than the water line behind it and newer than the outlet it is plugged into — which is why we ask about the remodel on the phone rather than being surprised by it in your kitchen.
How a visit works
-
You describe the symptom
On the phone, in plain words. What the cabinet is doing, when it started, and what the display says if it says anything. That is usually enough to know which parts to bring.
-
A flat diagnostic visit
One flat fee to come out, test the system and tell you what is wrong. It is credited toward the repair if you go ahead with the work.
-
A written estimate
You get a written estimate before any part is ordered or any labour begins.
-
The repair, and the warranty
Genuine OEM parts throughout. 90 days on labour, 365 days on parts.
Where we stand
- EPA Section 608 certified technicians
- Federal certification to recover, evacuate and charge sealed refrigeration systems. Required by law for anyone opening a sealed system, and genuinely held here.
- Independent shop, no dispatch fee
- You speak to the person who will be standing in your kitchen, not a call centre routing the job to whoever is nearest.
- Sub-Zero built-in work only
- Every day is spent on the same sealed systems, the same evaporator fans and the same control boards, in one product line.
We cover Beauclerc, Loretto, Julington Creek, Cormorant Landing, Cormorant Creek Estates, Egrets Landing and the rest of Mandarin within 25 miles — the streets we cover page breaks that down area by area.
Prices are on the what it costs page, the cover after a repair is on the warranty page, and the questions that come up on most first calls are answered on the questions page.
What it costs
What does a repair cost on this side of the river?
The whole book, published up front. Every line is a range because the firm figure is written down after the diagnosis, not before it.
| What is being put right | Parts and labour |
|---|---|
| Diagnostic visit | $80 flat, credited toward the repair |
| Door gasket or seal replacement | $240–$620 parts and labour, after the diagnostic |
| Evaporator or condenser fan motor | $250–$550 parts and labour, after the diagnostic |
| Defrost heater, thermostat or sensor | $250–$640 parts and labour, after the diagnostic |
| Ice maker, water valve or supply line | $250–$650 parts and labour, after the diagnostic |
| Electronic control board | $440–$820 parts and labour, after the diagnostic |
| Compressor or sealed-system repair | $940–$2,290 parts and labour, after the diagnostic |
Every line above is a range because the firm figure is written down after the diagnosis and not before it. The $80 covers coming out, testing the system and telling you what is wrong, and it comes off the repair the moment you say go ahead. The whole table, and what happens when a repair is not worth doing, is on the what it costs page.
Questions we are asked
What a first call usually asks
- What does a Sub-Zero repair cost in Mandarin?
- One flat fee to come out, test the system and tell you what is wrong. It is credited toward the repair if you go ahead with the work. Beyond it, the work falls into the published bands in the table above, and the firm figure is written down after the diagnosis rather than guessed at on the phone.
- Do you work on anything other than Sub-Zero?
- No. One manufacturer and one product family: built-in refrigerators and freezers, integrated columns, undercounter units, drawers, wine storage and ice machines. Sub-Zero makes no cooking appliances, so none appear anywhere here, and heating, air conditioning and ductwork are a different trade we do not enter.
- Are you connected to Sub-Zero in any way?
- No. Independent service. Not affiliated with Sub-Zero. The brand is named only to say what we work on. EPA Section 608 certification is the one credential claimed on this site, it is federal rather than a manufacturer credential, and it is genuinely held here.
- How far do you travel?
- ZIP 32223, 32257, 32258 and about 25 miles around the middle of Mandarin, which takes in the subdivisions, the historic centre and the riverfront along Mandarin Road. Distance changes how long a visit takes, never what it costs.

What owners in Mandarin said
Three that this page picked out of the pool, printed whole and not trimmed. Sixty-odd more sit beside the repair or the street each one came from.

A straight answer that the machine was fine and the water reaching it was not, which saved me a part I did not need. Booking the return slot took longer than I wanted, though the work itself was quick.

Three cold appliances in this house and the one in the back hall was the culprit. He looked over all of them while he was here and charged only for the visit and the part that had to change.

The beverage unit in the pool house had frost building at the back. He traced it to a door that had dropped very slightly rather than to the cooling, and brought it back into line on the spot.
