A fryer fails on a Friday. The engineer quotes for the repair. Is it worth doing, or are you propping up something that should have been replaced two years ago? There is no formula that answers this, but there is a reasonable way to think about it.
Age is a factor, not the factor
A well-maintained twelve-year-old range from a good manufacturer may have years left. A poorly-maintained five-year-old one may not. Age matters mainly because of what it implies — parts availability, accumulated wear, efficiency relative to current equipment — rather than in itself.
Parts availability is often the real deciding factor
This is the one that tends to settle the argument. If a control board is obsolete and the only source is a reconditioned unit with no warranty, you are not choosing between repair and replacement — you are choosing between replacement now and replacement shortly, having spent money in between.
Ask directly: is this part current, and what is the lead time? A repair that leaves you waiting three weeks for a component is a different proposition from one completed on the day.
Running cost
Older equipment is often less efficient, and cooking and refrigeration equipment runs for long hours. The gap is real but it is easy to overstate; be sceptical of anyone quoting a payback period without knowing your energy tariff or your hours of use. It is a genuine input to the decision, not the whole decision.
How critical is the item?
This gets underweighted. If the item going down closes your kitchen, the calculation is not just about the repair bill — it includes the cost of the next failure and the one after. A marginal repair on a non-critical item is reasonable. The same marginal repair on the only combi oven in a busy kitchen is a gamble with your trading.
The “50% rule”, and where it breaks down
A common rule of thumb: if the repair costs more than half of replacement, replace. It is a useful starting point and a poor stopping point, because it ignores three things — how long the repair is expected to buy you, whether other components are near the end of their life, and how much a failure actually costs your business.
A repair at 60% of replacement cost that restores a machine to good condition for another five years can be a better decision than one at 30% that fixes one symptom on equipment that is generally worn out.
What a good contractor should tell you
You should be told what has actually failed, whether anything else is close behind it, whether the part is available and how long it will take, and a straight opinion on whether the repair is worth doing. That last one matters most, and it is the one to listen for — because sometimes the honest answer means less work for the contractor giving it.
If you are told only a price with no reasoning behind it, ask for the reasoning.
A reasonable default
Repair when the fault is specific, the part is available, the rest of the machine is sound and the item is not the one thing standing between you and a closed kitchen. Replace when parts are drying up, when multiple components are failing in sequence, or when the item is critical and no longer dependable.
