Past Twenty-Five Years and Still Running
A built-in Sub-Zero past twenty-five years that still holds its temperature poses a quieter question: keep maintaining it, or plan the replacement before it fails.

No particular birthday retires a Sub-Zero that still holds its temperature
No age forces a working Sub-Zero out, and this page gives no year count, because none would be honest for your unit. One past twenty-five that still reaches its setting is doing its job.
What age changes is the cost of a surprise. Sub-Zero's longest sealed-system cover ends twelve years from installation, so any repair now is paid in full. The real choice is between looking after the unit on purpose and waiting to see what gives out first.

On a cabinet this old, much of the wear sits outside the sealed system
A unit that still cools has a working sealed system. The parts around it wear too:
- Door gaskets that have hardened, flattened or torn, letting warm air in so the compressor runs longer.
- Door hardware: hinges and closers that no longer pull a door fully shut.
- Fan motors in the cabinet or the machine compartment, which can grow noisy.
- The control, where a display or buttons become unreliable.
Gaskets, fans and the control each have a band well below the sealed-system figure; door hardware is priced after diagnosis. None of them says the unit is finished.

Column one
If you repair
- The work
Keep the unit maintained: the condenser cleaned on Sub-Zero's schedule, worn gaskets replaced, and smaller faults such as a fan or the control dealt with as they come.
- What it comes to
-
$300–$630 plateau range for door gasket or seal replacement
The $89 visit is credited against it once you say yes.
- Still unknown
When a larger fault will arrive, if it does, and what that repair will involve on a cabinet of this age when the time comes.
- This column wins when
The unit holds its setting, the cabinet is sound, the panels still suit the kitchen, and the household is content to pay for upkeep as it comes.

Column two
If you replace
- The work
Choose at leisure while the old unit still runs: the model, the panels, and the week the swap happens, rather than whatever can be delivered in a hurry.
- What it comes to
-
$11,550–$20,400 reference figure on the plateau for a comparable built-in replacement, before installation and cabinetry work
- Still unknown
How much running the old unit still had in it, which is what choosing early costs you.
- This column wins when
The doors, gaskets and control all need work at once, the kitchen is changing anyway, or a sudden failure would be hard to live with.

Keeping it going comes down to a clean condenser and doors that seal
Sub-Zero wants the condenser cleaned at intervals of six to twelve months, sooner with pets, and warns that skipping it can cause temperature loss or mechanical failure. The use and care guide for your model describes the job. Sub-Zero does not recommend chemical cleaners, and the aluminum fins should not be bent.
The gaskets are the other half. Look along each one for tears, hard or flattened stretches, and check that every door closes on its own. A worn gasket is the banded repair shown on this page, and Sub-Zero Repair Sammamish, (425) 610-8986, can fit one during a visit that starts with the $89 diagnosis.

A replacement planned ahead is chosen rather than grabbed
When a very old unit stops without warning, the next one is picked in a hurry, with food in coolers. Planned ahead, the decision gets time: the new model's installation guide set against the opening, and the cabinetmaker consulted on panels and trim.
Planning does not mean replacing now. It means knowing the model you would move to and what your opening would need, so that when the old unit does stop, you choose between two columns you already understand.

Asked about this situation
How long does a Sub-Zero last?
There is no honest single number. How long one keeps running depends on the model, how it was installed and how well its condenser, gaskets and fans have been looked after. Sub-Zero Repair Sammamish judges an old unit by what it does now, holding its temperature and sealing its doors, rather than by its age.
Is a very old Sub-Zero still efficient enough to keep?
Nobody can give you a figure without measuring your own unit. What helps any old unit is a clean condenser, gaskets that seal and doors that close by themselves, and all three are simple to check. Sub-Zero Repair Sammamish, (425) 610-8986, can look at each of them during the $89 diagnosis.
