Repair or replace: the arithmetic on a built-in

The question we are asked most often is not what is wrong with it. It is should I be spending this on a machine this old. It deserves a proper answer, and the honest one is longer than a rule of thumb about half the replacement cost.

A built-in is not a free-standing appliance

A free-standing range or refrigerator can be wheeled out and swapped in an afternoon. A built-in is part of the kitchen. Replacing a column refrigerator or a wall oven means the surrounding cabinetry, the decorative panel, the trim kit, frequently the electrical supply, and occasionally the countertop above it. The new unit has to fit an opening that was cut for the old one, and current models are not obliged to match a footprint from twenty years ago.

That is why a repair that looks expensive next to the shelf price of a new appliance is often still the cheaper answer once the kitchen is counted. The comparison people run in their heads — part and labour against a retail price — leaves out the trades.

What we actually weigh

Question	Why it moves the answer
What failed, and where does it sit?	A door, a fan or a board is bolt-on work. A sealed-system fault is a different order of job
How old is the cabinet?	Parts do not fail alone; a cohort of components reaches end of life within a few years of each other
Is the part still made?	An available part with a lead time is a repair. A discontinued part with no equivalent is not
Does the opening still match anything on the market?	If it does not, replacement drags cabinetry into the job
Has the appliance had this fault before?	A repeat failure usually points at the installation, not the part
Is it still inside its original cover?	If it is, using that cover is almost always the better move

The cohort argument, honestly stated

An appliance that has run for two decades has not been getting older in one place. Hinges, gaskets, fan motors, valves and boards all have service lives in the same broad range, and when the first of them goes it is normally telling you about the rest. That does not mean everything is about to fail — plenty of cabinets run on for years after one repair. It means a second repair within twelve months is a realistic outcome and should be part of the decision rather than a surprise afterwards.

We say this at the estimate rather than after the invoice. If we think a repair is buying a year, we tell you it is buying a year, and you get to decide whether a year is worth that price. Sometimes it plainly is: a kitchen being remodelled in eighteen months does not need a new refrigerator today.

Where we say do not repair

There are cases where the answer is no, and we would rather lose the job than take it.

• A sealed-system failure on a cabinet already well past twenty years, where the cost of recovery, repair and recharge lands close to a replacement that will come with a new life ahead of it.
• Any appliance that has stood in water. Silt gets where no procedure reaches, insulation holds moisture for months, and electronics that test clean on the day can fail without warning later.
• A part that is no longer produced and has no equivalent still in the supply chain. We will tell you that on the phone if the model and serial make it obvious, before you pay for a visit to hear it.
• Structural damage to the cabinet or the opening. That is a joinery job, and fitting parts around it only postpones the same call.

What that means on the estimate

Parts and labour go on separate lines, and where a repair is a holding action rather than a fix we write that down too. Sealed-system work is carried out by EPA Section 608 certified technicians and refrigerant is recovered rather than vented, which is part of why that particular repair costs what it does.

The flat $80 diagnostic buys the measurement and the written answer, including the answer do not spend money on this. That outcome is not a failed visit. It is frequently the most useful thing we do all week.
