Repair or Replace? A Cost Comparison Guide for Major Appliances

The question behind the question

"Is it worth fixing?" is really three separate questions bundled together: how much does the repair cost relative to replacement, how much useful life does the appliance likely have left, and is this an isolated failure or a pattern. Getting a clear answer requires looking at all three, not just the repair estimate in isolation.

The 50% rule of thumb, and its limits

A commonly cited guideline: if a repair costs less than about half of what a new, comparable appliance would cost, repair is usually the better deal. It's a reasonable starting point, but it has real limits. A $300 repair on a builder-grade dishwasher you're planning to replace anyway in two years is a different decision than the same $300 repair on a premium refrigerator you like and intend to keep for another decade.

Age matters, but not the way people assume

Typical expected lifespans: refrigerators 10-18 years, washers and dryers 10-13 years, dishwashers 9-13 years, ranges/ovens 13-20 years. An appliance well within its expected range with a single, isolated failure is usually a good repair candidate. An appliance near or past the upper end of its range is where the calculation shifts toward replacement, especially if the repair involves a major component like a compressor or a control board on an older, less efficient model.

One failure vs. a pattern

A first-time failure on an otherwise reliable appliance is usually worth fixing. An appliance that's needed three service calls in two years is telling you something different — even if this particular repair is cheap, the pattern suggests more failures are likely coming. At that point, the math shifts even if any single repair looks affordable on its own.

Energy efficiency: the factor people forget

A refrigerator or washer from 12-15 years ago can use meaningfully more energy and water than a current model, which is worth factoring in for appliances near the end of their expected lifespan — the ongoing utility cost difference over several more years of use is a real number, not a marketing talking point, even though it rarely shows up on the repair invoice itself.

What a straight answer looks like

When we diagnose an appliance that's a borderline repair-vs-replace case, we tell you both numbers plainly: what the repair costs, and roughly what you'd be looking at for a comparable replacement, so you're deciding with real information instead of a guess. If the repair clearly makes sense, we say so. If it doesn't, we say that too — even though it means less work for us that day.

A quick decision framework

• Repair usually makes sense: appliance is within its typical lifespan, this is the first or second issue, repair cost is under ~50% of replacement.
• Replacement is worth considering: appliance is at or past typical lifespan, repeated unrelated failures, repair involves a major component AND the unit is older/less efficient.
• Get a second data point either way: ask what a comparable new unit costs installed, and compare that to the actual repair quote — not a guess.
