# San Marco

> San Marco kitchens were drawn in the 1920s and the Southbank towers were not. Two different Sub-Zero service problems inside one neighborhood boundary.

Place: San Marco (32207), Duval County.
Dominant driver: Kitchen age. Housing: 1920s and 2000s.

San Marco is two service problems that happen to share a ZIP code. South and
west of the Square the kitchens were platted in the mid-1920s and the
constraints are carpentry and wiring. On the Southbank the kitchens are new, the
constraints are logistics, and almost nothing that applies in one half applies
in the other.

## The historic district half

The San Marco Historic District was platted in the mid-1920s, and its houses
were built with kitchens that no modern built-in was drawn for. What that means
on a service call:

**Openings that were widened once.** Usually decades ago, usually not square. We
measure the rough opening at three heights, and the narrowest reading is the one
that governs. A quarter inch short at the floor is enough to hold a door out of
parallel with the frame, and no gasket seals that.

**Exhaust paths that were closed off.** A built-in rejects heat through the
grille at the top and needs a clear route out of the cabinetry. In these houses
a soffit or a run of crown moulding returned across the opening is common, and
the machine ends up recirculating its own discharge air. Head pressure rises,
the compressor runs long, and the cabinet loses ground on a hot afternoon. The
complaint is always "it is not cooling", never "the exhaust is blocked".

**No dedicated circuit.** A kitchen wired before the appliance category existed
usually has the refrigerator sharing with the counter receptacles. The symptom
is intermittent and it looks like a control fault, which is why we read voltage
under load before we quote a board.

**Floors that move.** Heart pine over long spans shifts seasonally. A cabinet
set level at installation can rack enough within a year to break door-seal
contact along the hinge side, and the first complaint is condensation. Shimming
and realigning the doors is the repair. A replacement gasket on a racked cabinet
buys one season.

## The Southbank half

The high-rise units are a separate proposition entirely: newer kitchens, square
openings, dedicated circuits, and cabinets that were installed correctly by
somebody who had the drawings. What replaces the carpentry problem is access.

Service in a tower runs on the building's terms. Freight elevator booking,
certificate requirements, a loading dock with hours, protection for common
corridors, and a route from the dock to the unit that is longer than most people
expect. We arrange that ahead of the visit rather than arriving and discovering
it, because a technician standing in a lobby is being paid for nothing.

The equipment mix is different too. Tower kitchens run more integrated columns
and undercounter cabinets and fewer wide side-by-sides, simply because the
openings are narrower. A column is serviced the same way but it is a taller,
heavier unit in a tighter space, and where one has to come forward at all it is
a two-person job on protected flooring.

## What we check first, in both halves

The order does not change even though the neighborhood does. Shelf temperature
in both compartments with our own probe, because a built-in runs two independent
sealed systems and knowing which one is warm eliminates half the expensive
possibilities immediately. Then the condenser deck and the temperature of the
air leaving the grille, because lost airflow presents exactly like a low charge
and costs a fraction as much to fix. Then voltage at the receptacle while the
compressor starts.

Only after those three does an interior panel come off to read the frost pattern
on the evaporator, and only after that does anyone reach for gauges.

## Parts and the serial plate

The model and serial plate sits inside the fresh-food compartment on the upper
left side wall. It is worth finding before we arrive, because built-in
refrigeration is produced in long-lived platforms with running changes, and
gaskets, boards and fan assemblies are frequently specific to a serial range
rather than to the model as a whole. Ordering against the model alone is how the
wrong part arrives and a repair loses a week.

Where a component has been superseded or is no longer stocked, that goes on the
estimate before you approve it, not after.

## Terms

Flat diagnostic fee, credited toward the repair. Written estimate before any
part is ordered. We are independent of the manufacturer and we service Sub-Zero
refrigeration only.
