Both compartments went warm together after the power came back on. He tested the board rather than assuming, found the relay side dead, and explained why a surge weeks earlier could be the cause.

What independent actually means here
Riverbend Refrigeration works for the homeowner, not for a manufacturer. That distinction changes what we can tell you, and it is worth being precise about.
We are an independent appliance repair company. We are not affiliated with, authorized by, or endorsed by Sub-Zero or its parent company, Sub-Zero Group, Inc. We are not a factory service center and we do not hold a manufacturer service appointment. Anyone who tells you otherwise about us is wrong, and a manufacturer's own service locator will confirm it in about ten seconds.
What we are is specialists in one product line. We diagnose and repair Sub-Zero built-in refrigeration and nothing else, because the failure modes on this equipment are specific and a technician who splits their week across eight brands never gets deep on any of them.
It is worth saying the other half plainly, because the trade names overlap and search engines confuse them constantly. Sub-Zero is an appliance manufacturer — the badge on the built-in refrigerator in the kitchen — and refrigeration inside that cabinet is the whole of our work. We do not install, service or diagnose heating, air conditioning, air handlers, house thermostats or ductwork. We are not an HVAC contractor and not a ventilation contractor. We do not take other manufacturers, and we do not take cooking, laundry or dishwashing appliances of any make. If that is what you need, the phone call is a short one and it costs you nothing.
General note 1 — scope of work
- On the ticket
- Built-in and integrated Sub-Zero refrigeration, indoors, in a kitchen or a pantry: refrigerators, freezer and refrigerator columns, undercounter cabinets, wine storage and ice machines. The sealed system, the controls, the fans and defrost, the door and its gasket, and the opening the cabinet is trimmed into.
- Not on the ticket
- Heating and air conditioning. We do not install, service or diagnose furnaces, heat pumps, air handlers, condensing units for the house, thermostats for the house, or ductwork. We are not an HVAC contractor and not a ventilation contractor, and we do not hold ourselves out as either.
- Not on the ticket either
- Any other manufacturer, and any cooking, laundry or dishwashing appliance of any make. One product line from one maker is the entire reason we are useful on it.
- The name
- Sub-Zero on this site means the appliance manufacturer — the name stamped on the built-in refrigerator in the kitchen. It is a refrigeration brand, not a heating or cooling contractor with a similar name.
How a visit works
The diagnostic is $80, flat. Flat diagnostic fee, credited in full toward the repair if you approve the work. We measure before we quote — fill volume, actual voltage under load, temperature at the point that matters — and you get a written number before anything is ordered. Written estimate before any part is ordered or any labor is billed.
Completed work carries 90 days on labor and 365 days on parts. Genuine OEM parts sourced through the manufacturer supply chain. The fee is set out in full on the pricing sheet, the cover on the warranty sheet, and the rest on the questions sheet.
Where we work
Jacksonville, Florida, within roughly 35 miles. This is a mobile operation: there is no shop counter to visit, and we do not publish a street address for one that does not exist.
-
EPA Section 608
Universal certification for handling refrigerants, required for any sealed-system work on a Sub-Zero.

Independent operator
We are not a manufacturer service center. We buy OEM parts and we work for the homeowner.
-
Written estimate first
Every job is quoted in writing after diagnosis. Nothing is ordered until you approve the number.

Levelling and the panel alignment took longer than I expected, and the reveal needed a second pass the following week. Done properly in the end, and the door has closed cleanly ever since.

The seal work was done properly and the sweating stopped. What I did not like was being told a part was in stock when it was not, and finding that out on the day of the second visit.
