# Stage 2: Air, Condensers and Cabinet Clearance

Stage two of a Sub-Zero diagnostic in Nocatee: condenser condition, grille and toe-kick clearance, and the heat a built-in cabinet has to get rid of.

**Stage 2 of 6.** Every unit. It matters most on undercounter and island installations.

A refrigerator does not make cold. It moves heat out of a box and rejects it
into the room, and everything about a built-in installation makes that harder
than it is for a freestanding appliance. This stage is about whether the heat
has anywhere to go.

## The grille comes off before anything else

A built-in rejects its heat through a condenser behind a grille — at the top of
the cabinet on a full-height unit, at the toe-kick on an undercounter one. Both
are covered by joinery, and both collect exactly what a kitchen floor collects:
dust, pet hair, and the fine grey felt that builds up on aluminium fins over a
few years.

A coil in that condition adds head pressure to a system that is already working
against Florida ambient heat for eight months of the year. What the owner
experiences is long run times, poor recovery after the door has been open, a
cabinet sitting a few degrees above setpoint through the summer, and more noise
than there used to be. That is, word for word, the complaint list of a failing
compressor — which is why it is worth ten minutes and a torch before anybody
starts talking about sealed systems.

## Clearance is part of the appliance

The second half of this stage is the opening the cabinet sits in. Built-in
refrigeration is specified with clearances around it, and those clearances get
consumed over time by things that had nothing to do with the appliance:

- A cabinet run refitted after the appliance was installed, with a filler panel
  that now sits over part of the grille.
- Crown or trim added above a full-height unit, closing the gap the top vent
  was drawing through.
- An undercounter unit in an island, venting into the stillest air in the room,
  with a dishwasher two cabinets away adding its own heat to the same pocket.
- Storage packed in behind or beside a unit that was installed with a service
  gap around it.

None of that is a fault in the appliance, and none of it can be fixed by
replacing a part. It is also invisible from the front, which is why owners are
often certain nothing has changed.

## Coastal cabinets get a second look

Along the ocean — 32082, 32250, 32233 — salt-laden air adds a corrosion load
that inland cabinets do not carry. Aluminium condenser fins lose surface area to
it, which reduces heat rejection just as effectively as a coil packed with dust,
and it does so on a coil that can look clean from a distance. Exterior stainless
pitting is cosmetic, but it is a reliable indicator of how hard the air is
working on everything else in the cabinet. Nocatee is inland and does not carry
that load; there is no reason to price it into a 32081 job.

## What finishing this stage rules out

That a warm cabinet with a long duty cycle is a refrigeration fault. It usually
is not. It also rules out any later reading being misinterpreted, because a
sealed-system measurement taken behind a restricted condenser is not wrong so
much as meaningless — the system is doing what a healthy system does when it is
asked to reject heat into a blanket.

## The one thing an owner can influence

This is the only stage of the six where the householder can genuinely change the
outcome. A condenser cleaned on a sensible interval buys years on a compressor,
and the interval that suits a kitchen with two dogs is not the interval that
suits a kitchen with none. We will show you the grille, show you what the coil
looks like now, and tell you the interval we would use — not sell you a
subscription.

The diagnostic is $129 flat, credited toward the repair if you go ahead, with a
written estimate before any part is ordered. We are an independent company
servicing Sub-Zero refrigeration only.
