Repair or Replace? An Honest Framework for Appliance Decisions
The 50% rule is a starting point, not an answer. Here's what actually matters when deciding whether to fix or replace.
The 50% rule — useful but incomplete
The standard heuristic: repair if cost is under 50% of replacement; replace if over. This is reasonable as a starting point but it misses three important questions:
- How old is the appliance relative to its expected lifespan?
- What brand tier is it (mainstream vs. premium)?
- Is this the first major repair, or part of a reliability cluster?
Once you answer those, the decision usually becomes clear.
Age curves by appliance type
Appliances don’t fail uniformly across their life. Most have a “bathtub curve” — early failures in the first 1-2 years (warranty-covered), reliable middle period, then increasing failure rate as they age. Here’s the typical curve by appliance type:
Refrigerators
| Age | Mainstream brands | Premium brands |
|---|---|---|
| 0-5 years | Almost always repair | Almost always repair |
| 5-10 years | Repair if under 50% | Repair if under 70% |
| 10-15 years | Repair major issues only | Repair if under 60% |
| 15+ years | Replacement preferred | Repair still often makes sense |
Washers and dryers
| Age | Mainstream brands | Premium brands |
|---|---|---|
| 0-5 years | Almost always repair | Almost always repair |
| 5-8 years | Repair if under 50% | Repair if under 70% |
| 8-12 years | Repair simple issues; replace major failures | Repair if under 60% |
| 12+ years | Replacement preferred (except Speed Queen, Miele) | Repair often still makes sense |
Dishwashers
| Age | Mainstream brands | Premium brands (Bosch, Miele) |
|---|---|---|
| 0-5 years | Almost always repair | Almost always repair |
| 5-8 years | Repair if under 50% | Repair if under 65% |
| 8-12 years | Repair simple issues only | Repair if under 55% |
| 12+ years | Replacement preferred | Bosch/Miele repair often still makes sense |
Ovens and ranges
| Age | Mainstream | Premium (Wolf, Viking, Thermador) |
|---|---|---|
| 0-10 years | Almost always repair | Almost always repair |
| 10-15 years | Repair if under 50% | Almost always repair |
| 15+ years | Evaluate | Repair still often justified |
Premium ranges (Wolf, Viking, Thermador) have particularly long expected lifespans because the heavy-duty mechanical components routinely outlast 25 years. The electronic components fail more predictably and are replaceable.
Brand tier dramatically changes the math
Mainstream brands
For Samsung, LG, GE, Whirlpool, KitchenAid, Bosch (non-flagship), Maytag, Frigidaire, the 50% rule works well. Replacement costs:
- Refrigerator: $1,500–$3,500
- Washer: $700–$1,800
- Dryer: $700–$1,500
- Dishwasher: $700–$1,500
- Range: $1,000–$3,500
A $400 repair on a $1,500 mainstream refrigerator (27% of replacement) is clearly worth it. A $900 repair on the same unit (60%) gets harder if the unit is 10+ years old.
Premium brands
For Sub-Zero, Wolf, Viking, Thermador, Miele, Bosch 800/Benchmark, Gaggenau, the math is different. Replacement costs:
- Sub-Zero refrigerator: $7,000–$15,000+
- Wolf range: $5,000–$15,000+
- Viking range: $6,000–$15,000+
- Thermador Pro Grand range: $9,000–$20,000+
- Miele dishwasher: $1,500–$3,000+
- Miele washer/dryer pair: $4,000–$6,000+
A $1,500 repair on a $10,000 Sub-Zero (15% of replacement) is obvious. A $2,500 repair on the same unit (25%) is still excellent value. Even $4,000 in repairs (40%) makes sense given replacement cost.
The threshold to consider replacement on premium brands is generally 70-80% of replacement cost AND unit age beyond 15 years.
Reliability clusters — the early warning
The single most overlooked factor: multiple unrelated repairs in a short time window.
If you’ve had three different repairs on the same unit in 18 months — refrigerator water valve in January, defrost system in April, ice maker in August — that’s not just bad luck. That’s a reliability signal. The unit is entering its decline phase, and additional repairs over the next 12-24 months are likely.
In this case, the math shifts. Even if the current repair quote is under 50% of replacement, the cumulative cost of likely future repairs makes replacement the better long-term call.
We tell customers when we see reliability clusters. We don’t pretend the next repair will be the last one if patterns suggest otherwise.
Environmental factors specific to LA
Hard water. LA tap water averages 350+ ppm hardness (very hard). This affects dishwashers, ice makers, water heaters, and washer water valves. Hard-water-adjacent appliances typically have shorter lifespans (15-25% reduction). Annual filter changes and maintenance partially offset.
Coastal salt air. Homes within 5 blocks of the Pacific (Santa Monica, Venice, Marina del Rey, Manhattan Beach, Pacific Palisades coast-side) see accelerated corrosion on stainless steel, condenser coils, electrical contacts. Plan on 20-30% shorter typical appliance life unless aggressive maintenance schedule is followed.
Energy costs. Older appliances cost significantly more to operate. A 15-year-old refrigerator may use $150–$300/year more electricity than a current ENERGY STAR equivalent. Over 5 years, that’s $750–$1,500 in energy savings if you replace — material factor in the decision.
How we approach the math
When we diagnose your appliance, we give you the repair quote AND the math (see also when to replace a refrigerator and our repair cost guide):
- Cost to repair (flat rate, all-in)
- Estimated remaining life if repaired (years)
- Replacement cost for equivalent unit
- Whether we recommend repair, replacement, or “go either way”
We don’t push repair when replacement is the better call. Our $85 service call is waived even if you decide to replace — we charge for completed repair work, not for honest advice.

FAQ
What is the 50% rule for appliance repair?
The 50% rule: if repair cost exceeds 50% of replacement cost, replace. If under 50%, repair. This is a reasonable starting heuristic but misses critical context like age, brand tier, and failure history. The rule works best for mainstream brands (Samsung, LG, Whirlpool) on units under 10 years old. Premium brands (Sub-Zero, Wolf, Miele) often justify repair well past the 50% threshold given high replacement costs.
How long do refrigerators typically last?
Mainstream brands (Samsung, LG, GE, Whirlpool, KitchenAid) typically last 10-15 years. Premium brands (Sub-Zero, Thermador, Viking, Miele) routinely run 18-25+ years with proper maintenance. Sub-Zero compressors carry 12-year warranties as evidence of expected longevity. LG refrigerators 2014-2017 had linear-compressor reliability issues; check class-action settlement coverage if your unit is from those years.
How long do washers and dryers last?
Mainstream washers and dryers typically run 10-13 years. LG direct-drive units (no belt) often run 12-15 years given the mechanical simplicity. Miele washers and dryers are rated for 10,000 hours of operation — roughly 20 years of typical household use. Speed Queen commercial-grade units routinely run 15-20 years. Whirlpool/Maytag mainstream is solid 10-15 year territory.
How long do dishwashers last?
Mainstream dishwashers (Samsung, LG, GE, Whirlpool, KitchenAid) typically last 8-13 years. Bosch dishwashers routinely run 12-15 years. Miele dishwashers can run 15+ years. LA hard water (350+ ppm hardness) shortens dishwasher life by 15-25% compared to soft-water markets — annual filter cleaning extends life significantly.
When should I replace my appliance instead of repairing it?
Replacement makes sense when: (1) repair cost is over 50% of replacement AND age is past typical lifespan; (2) you've had multiple unrelated repairs on the same unit in 18 months (reliability cluster); (3) sealed-system refrigerator failure on a unit 12+ years old; (4) ongoing maintenance has been deferred and you'd be playing catch-up. For premium brands, the threshold for replacement is higher — repair up to 70-80% of replacement often makes sense.
How do I know when my refrigerator is dying?
Warning signs: running constantly without reaching set temperature, frequent thermostat adjustments needed, water/condensation accumulation, unusual noises (especially compressor sounds), ice maker issues, food spoiling faster than usual, energy bills increasing. Any single sign doesn't mean replacement is needed — but multiple signs together suggest evaluating the math. A pre-failure diagnostic visit ($85, waived with any work) tells you what's coming and what it costs.
Are premium appliances worth repairing more often than mainstream?
Yes. Sub-Zero refrigerator replacement runs $7,000–$15,000+; Wolf range replacement $5,000–$15,000+; Miele washer/dryer replacement $2,500–$5,000+. Repairs up to $2,000–$3,000 on these premium brands often make economic sense because the alternative is a major capital expense. Premium brand durability also tends to deliver another 5-10 years post-repair on properly-maintained units.
