## Repairs we accept
- [Ice machines that will not harvest, and ice makers that have stopped](https://subzerorepairstaugustine.com/repairs/ice-machines/): Thin cubes, a mould that will not release, a fill valve passing less than the control believes, or a unit that has quietly stopped making ice at all.
- [Built-in refrigerators and freezers](https://subzerorepairstaugustine.com/repairs/built-in-refrigerators/): A cabinet that will not hold temperature, a compressor that never cycles off, frost where there should be none, or a door that no longer sits flush in its opening.
- [Integrated refrigerator and freezer columns](https://subzerorepairstaugustine.com/repairs/integrated-columns/): Panelled columns sit flush with the cabinetry, which makes access, alignment and airflow a different job from a standard built-in.
- [Undercounter units that cool in winter and fail in August](https://subzerorepairstaugustine.com/repairs/undercounter-refrigeration/): Small cabinets in hot locations — under an island, in a butler's pantry, or out on a lanai where the summer air is working against them.
- [Wine storage cabinets and wine columns](https://subzerorepairstaugustine.com/repairs/wine-storage/): A wine cabinet is judged on stability rather than cold, and the faults that matter are the ones that let a zone drift a few degrees at a time.
- [Sealed systems, compressors and refrigerant faults](https://subzerorepairstaugustine.com/repairs/sealed-systems/): Refrigerant faults are the expensive end of the trade, which is exactly why they should be measured and proved before anybody quotes for them.
- [All repairs, on one index](https://subzerorepairstaugustine.com/repairs/): Every category of work this shop takes on.

## Where we work
- [Palencia (32095)](https://subzerorepairstaugustine.com/districts/palencia/): Inland. A twenty-year-old master-planned community where the refrigeration was specified into the cabinetry — and where the first generation of it is now old enough to need us.
- [World Golf Village (32092)](https://subzerorepairstaugustine.com/districts/world-golf-village/): Inland. One large inland ZIP code holding three distinct generations of kitchen, from late-1990s built-ins to appliances still under construction dust.
- [Anastasia Island (32080)](https://subzerorepairstaugustine.com/districts/anastasia-island/): Coastal. A barrier island ZIP code where ocean air, outdoor installations and long empty stretches decide how quickly an appliance ages.
- [the Old City (32084)](https://subzerorepairstaugustine.com/districts/old-city/): Coastal. Old houses, narrow doorways, salt off the Matanzas, and cabinet openings that were never cut for a modern built-in.
- [Fruit Cove (32259)](https://subzerorepairstaugustine.com/districts/fruit-cove-st-johns/): Inland. The north-west corner of the county: newer kitchens, several machines per household, no salt in the air, and the longest drive on our map.
- [All districts](https://subzerorepairstaugustine.com/districts/): The whole service map, ZIP by ZIP.

## Notes from the shop
- [Reading a Condenser Before It Fails](https://subzerorepairstaugustine.com/notes/reading-a-condenser/): A built-in refrigerator gives you two or three months of warning before it loses temperature. Most of that warning shows up at the condenser.
- [Two Systems, Not One: Dual Refrigeration](https://subzerorepairstaugustine.com/notes/two-systems-not-one/): The most useful sentence an owner can say on the telephone is which half of the cabinet is wrong. Here is why that one observation is worth so much.
- [Storm Season and the Control Board](https://subzerorepairstaugustine.com/notes/storm-season-and-control-boards/): A board that survives a strike but loses one output is the most misleading fault we see. It presents exactly like a failing sealed system, and it is not one.
- [Where an Ice Machine Actually Fails](https://subzerorepairstaugustine.com/notes/inside-the-ice-machine-cycle/): Four steps run in sequence, and each one fails in a way an owner can see from the kitchen. Here is what each failure looks like, and the order we check them in.
- [Closing a Coastal House for the Season](https://subzerorepairstaugustine.com/notes/closing-a-coastal-house/): An appliance left running in a closed, humid house is not resting. Here is what we would do before the shutters go up, and what we would leave alone.
- [All notes](https://subzerorepairstaugustine.com/notes/): Written notes on how these cabinets fail and what it takes to put them right.
