The fastest honest answer most techs use is the "50% rule": if a repair will cost more than half the price of a comparable new unit — and the appliance is past about half its expected life — replacing usually wins. If the repair is well under half, fixing is almost always the smarter money. Everything else (age, energy use, parts availability, how the rest of the machine looks) just sharpens that line.
That said, the rule is a starting point, not a verdict. A five-year-old fridge with a failed fan motor is a clear fix; a fourteen-year-old fridge needing a sealed-system repair is a clear replace. Below is how an experienced GTA tech actually weighs it — with real lifespan ranges, honest cost framing confirmed on-site, and the cases where the answer isn't close.
The 50% rule, and why it's only half the story
The 50% rule is the most widely repeated guideline in the trade: if a repair costs 50% or more of a comparable new appliance, lean toward replacing. Below half, repair. It's popular because it works most of the time — past the halfway mark you're paying premium dollars for diminishing returns on a machine that's already aged.
But price alone can mislead. The more complete version technicians use is the 50/50 rule: weigh the repair cost and the appliance's age together. If a unit has passed roughly half its expected lifespan and the repair exceeds half the replacement cost, replacement is the rational call. If only one of those is true, it's a genuine judgement call — and that's exactly the conversation worth having before you spend anything.
One more factor the rule hides: appliances age as systems, not as isolated parts. When one major component fails after years of heat, vibration, or electrical stress, the others are often not far behind. A cheap fix on a tired machine can buy you a few months rather than a few years — which is why an on-site look at the whole unit matters more than a number off a chart.
Know the lifespan of what you own
Half the decision is just knowing where your appliance sits on its own clock. The figures below are widely published industry averages (life-expectancy data compiled by Mr. Appliance, consistent with the long-cited National Association of Home Builders study). Yours may run shorter or longer depending on use, water hardness, and maintenance:
- Refrigerator: around 13–14 years
- Clothes dryer: around 13–14 years (gas tends to run slightly shorter than electric)
- Washing machine: around 10–12 years
- Dishwasher: around 9–12 years
- Gas range/stove: around 15–19 years
- Electric range/oven: around 13–16 years
The practical takeaway: ranges and ovens are the survivors — a 12-year-old stove with a bad igniter or element is very often worth fixing. Dishwashers and washers tend to tip toward replacement sooner, because they hit middle age earlier and accumulate wear (pumps, bearings, seals) faster. A dishwasher at year 8 with a failed pump is a much closer call than a stove at year 8 with the same dollar repair.
Cost of repair vs. cost of new (honest GTA framing)
To apply the 50% rule you need two real numbers: a confirmed repair quote and a fair replacement price. Both deserve honesty. A like-for-like new mid-range appliance in the GTA — delivered, installed, old unit hauled away — usually costs more than the sticker, so factor delivery and disposal into the "new" side of the math.
On the repair side, our pricing works like this: a flat diagnostic fee that's credited toward the repair if you proceed, then a written, all-in quote before any work starts. There are no fake exact quotes here — common faults fall into typical ranges that we confirm on-site once we've seen the actual fault, the model, and the part needed. A dryer that won't heat, for example, is frequently a blown thermal fuse (a one-time safety part that trips on restricted airflow or overheating) or a failed heating element — both common, very fixable repairs on most machines. A bad door latch, igniter, fan motor, or control board each carries its own honest range.
The point of the diagnostic isn't to sell a repair — it's to give you a real number so the 50% math is based on facts, not a guess. If the honest quote clears the replace line, we'll tell you. If you'd like the repair-side ranges for your specific appliance, the dryer, washer, and dishwasher hubs each list common problems with honest cost ranges.
Don't forget the energy bill
Efficiency rarely decides a repair on its own, but for refrigerators it can quietly change the math. A fridge runs 24/7, and an old one is often the single biggest energy draw in the kitchen. Per ENERGY STAR and U.S. Department of Energy data, an older refrigerator uses on the order of 35% more energy than a current ENERGY STAR model. The annual cost difference depends on the unit's age and your hydro rate: a 15-plus-year-old fridge can cost on the order of $80–$100+ more per year to run than a new one, and a model from the 1980s or earlier can add several hundred dollars a year.
So if you're staring at a borderline repair on a 12-to-15-year-old fridge, the energy savings of a new one can tip a close call toward replacement over a few years. For dishwashers and washers, newer models also use noticeably less water and energy per cycle, which matters on a metered GTA water bill. For dryers, stoves, and ovens, the efficiency gap between old and new is much smaller — so energy almost never justifies replacing a perfectly fixable stove or oven.
When to DEFINITELY repair
Some repairs are easy yes's. Lean hard toward fixing when:
- The appliance is under about half its expected lifespan. A 3–6 year old machine has years left; protect that investment.
- The fault is a single, well-understood part: a fridge door gasket or fan motor, a dryer thermal fuse or heating element, a washer drain pump or door lock, a dishwasher pump, an oven igniter or bake element, a stove burner switch.
- The repair lands well under 50% of replacement — and the rest of the machine is mechanically sound.
- It's a high-end or built-in unit (Sub-Zero, Wolf, Miele, Viking, Thermador, Bosch, KitchenAid built-ins). These are expensive to replace and built to be serviced for a long time, so the repair math favors fixing far longer than it does for a budget model.
For high-end and panel-ready built-ins especially, replacement often means cabinetry and counter work too — which pushes the "new" cost so high that repair almost always wins.
When to DEFINITELY replace
Other times the kindest advice is to stop spending. Lean toward replacing when:
- The repair clears the 50% line and the unit is past mid-life. Both conditions true = replace.
- It's a sealed-system / compressor failure on an older fridge, or a cracked tub / failed bearing on an older washer. These are the costliest repairs and tend to arrive when other parts are also near end-of-life.
- Parts are discontinued. If the manufacturer no longer makes a critical OEM part, even a willing tech can't keep the machine alive long-term.
- You're on the third or fourth repair in a short span. Repeated failures on an aging machine are the machine telling you it's done.
- Any safety issue that can't be fully and reliably corrected — a gas leak, a persistent electrical fault, or a control board that won't behave.
A good tech will say "replace" out loud when that's the truth — there's no benefit in selling you a repair that won't hold.
How a proper diagnosis settles it
Charts and rules get you to a hypothesis. An on-site diagnosis gets you to the right answer. When our lead technician Anthony — Red Seal qualified, 313A-licensed, and TSSA-certified — or a member of his team looks at the machine, the goal is a straight verdict: here's the fault, here's the honest cost to fix it with OEM parts, and here's whether that clears or stays under your replace line.
We service the major brands — Whirlpool, LG, GE, Samsung, Maytag, Frigidaire, KitchenAid, Bosch, Miele, Sub-Zero, Wolf, Viking, Thermador, Electrolux, Kenmore, JennAir, and more — across Toronto and the GTA. We carry $2M general liability insurance and back our work with a workmanship warranty. If the smart move is to replace, we'll tell you that for the price of the diagnostic, not a repair you didn't need.

Frequently asked questions
What exactly is the 50% rule for appliance repair?
It's a guideline saying you generally shouldn't spend more than half the cost of a comparable new appliance on a repair. If the fix is under 50%, repair is usually the smarter money; at or above 50% — especially on an older unit — replacement tends to win.
How old is too old to repair an appliance?
There's no hard cutoff, but a useful rule of thumb is the appliance's mid-life: very roughly the 5–7 year mark for a dishwasher or washer, 6–7 years for a fridge or dryer, and 8–10 years for a stove or oven. Past mid-life, a costly repair leans toward replacement; before it, repair usually makes sense.
Is it worth repairing a high-end or built-in appliance like Sub-Zero or Miele?
Usually yes. Premium and built-in units are expensive to replace (often with cabinetry work too) and are designed to be serviced for many years, so the repair math favors fixing them far longer than it does a budget model.
Does a new energy-efficient appliance really save enough to justify replacing?
For refrigerators it can matter — an old fridge uses around 35% more energy than a current ENERGY STAR model, which adds up since it runs 24/7. For dryers, stoves, and ovens the efficiency gap is small, so energy savings rarely justify replacing a fixable unit.
Do I pay for the diagnostic if I decide to repair?
There's a flat diagnostic fee, and it's credited toward the repair if you proceed. You get a written, all-in quote before any work begins, so you can apply the 50% rule to real numbers.
My dryer stopped heating — repair or replace?
Usually repair. No-heat on a dryer is very often a blown thermal fuse (a safety part) or a failed heating element — both common, fixable repairs that fall well under the replace line on most machines. We confirm the exact fault and cost on-site.
