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. [Where we work](https://subzerorepairflemingisland.com/shores/) Shores ## The places we drive to ### [Fleming Island](https://subzerorepairflemingisland.com/shores/fleming-island/) Clay County work, from the Doctors Lake shoreline through Eagle Harbor and Pace Island to the older river lots along Hibernia. ### [Eagle Harbor](https://subzerorepairflemingisland.com/shores/eagle-harbor/) 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](https://subzerorepairflemingisland.com/shores/pace-island/) 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](https://subzerorepairflemingisland.com/shores/hibernia-plantation/) 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](https://subzerorepairflemingisland.com/shores/doctors-lake/) 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](https://subzerorepairflemingisland.com/shores/orange-park/) 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.

[Read every one of them](https://subzerorepairflemingisland.com/reviews/). ★★★★☆ 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. Meredith Q.2026-04-24 ★★★☆☆ Work was done properly and the cabinet holds. My reservation is the scheduling: the second appointment moved twice, and both times I found out only because I called to confirm it myself. Ignatius B.2025-08-26
