The old rule of thumb, replace if the repair costs more than half the appliance, was written for disposable appliances. It does not fit a built-in Sub-Zero, a Wolf range, or a Gaggenau wall oven, which are engineered for two or three decades of service and use parts that stay available for years. The honest math for luxury appliances usually favors repair, but not always, and we will tell you when it does not.
What High-End Appliances Are Built to Do
A big-box refrigerator is designed to a price and typically lasts 8 to 12 years. A built-in Sub-Zero is designed to a standard and routinely runs 20 years or more, often on its original sealed system. That difference changes the calculation. Spending a few hundred dollars on a defrost heater or evaporator fan to get another decade out of a unit that would cost 12,000 dollars and a cabinetry refit to replace is rarely the wrong choice.
The Five Questions We Ask
- Is it built-in or integrated? Panel-ready and column units are matched to cabinetry. Replacement often means carpentry, not just an appliance swap.
- What failed? A control board, fan, heater, valve, or gasket is a routine repair. A failed compressor or a leaking sealed system on a very old unit is a bigger decision.
- How old is it, honestly? Under 15 years, repair almost always wins. Past 20, we weigh the specific failure.
- Are parts available? For the brands we service, they usually are. Where a part is discontinued we can often source the correct equivalent.
- Is this the first major failure or the third? A pattern of sealed-system faults on an aging unit changes the answer.
| Situation | Typical Guidance | Why |
|---|---|---|
| Fan, heater, valve, board, gasket | Repair | Routine parts, long remaining life |
| Built-in under 15 years old | Repair | Well within design life |
| Sealed-system leak, unit 8-15 yrs | Repair, sealed-system work | Worth restoring a modern built-in |
| Sealed-system failure, 22+ yrs | Weigh carefully | Compare cost to a matched replacement |
| Cosmetic or single control fault | Repair | Small fix on a valuable appliance |
The Costs Replacement Hides
The sticker price of a new built-in is only part of the story. Add delivery and installation, the electrician or plumber if connections move, possible cabinetry modification for a unit that is not a perfect size match, disposal of the old appliance, and weeks of lead time. A repair that returns your existing appliance to service this week frequently costs a fraction of that all-in figure.
When We Recommend Replacement
We will point you toward replacement when an older unit has a failed sealed system that would cost as much as a significant share of a new appliance, when a discontinued critical part genuinely cannot be sourced, or when a unit has a history of unrelated major failures that signals the end of its economic life. Those cases are the exception, not the rule.
Not Sure Whether to Fix It?
Book a diagnosis and get an honest written recommendation. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
