FAQWhen your refrigerator stops cooling, your washer won't drain, or your oven won't heat, you face a critical decision: Should I repair this appliance, or is it time to replace it?
The answer isn't always obvious. A $200 repair might seem expensive until you realize a new appliance costs $1,500. On the flip side, repairing a 15-year-old unit that's near the end of its lifespan may just delay the inevitable.
Here's a professional framework to help you make the smartest financial decision:

The 50% Rule: Your Primary Decision Tool
The appliance repair industry uses a simple formula called the 50% Rule:
The 50% Rule Formula:
If repair cost > 50% of replacement cost AND appliance is past 50% of its expected lifespan, consider replacement.
Example: Your 7-year-old refrigerator (expected lifespan: 13 years) needs a $700 repair. A comparable new refrigerator costs $1,400.
Factor #2: Appliance Age & Expected Lifespan
Average appliance lifespans:
Refrigerators
10–13 years
Washers
10–12 years
Dryers
10–13 years
Dishwashers
9–10 years
Ovens & Ranges
13–15 years
Microwaves
8–9 years
Rule of thumb: If your appliance is within the last 3 years of its expected lifespan, replacement usually makes more financial sense than major repairs.
Factor #3: Energy Efficiency Gains
Appliances manufactured today are 10-50% more energy-efficient than models from 10+ years ago. This is especially true for refrigerators, dishwashers, and washers.
Financial impact: A new Energy Star refrigerator can save $50-$100+ per year on electricity compared to a 10-year-old model. Over 10 years, that's $500-$1,000 in savings.
When to factor this in: If your appliance is old, inefficient, and requires a costly repair, the energy savings from a new model can justify replacement even if the 50% rule is borderline.

Factor #4: Repair Frequency
If you've had to repair the same appliance 2-3 times in the past year, that's a red flag.
Why? Multiple repairs signal cascading failures. Once one component fails, others often follow shortly after—especially in older units.
Decision guideline: After the second major repair in 12 months, strongly consider replacement.
Factor #5: Warranty Coverage
Most appliances come with a 1-year manufacturer warranty. Many premium brands offer extended warranties on key components (e.g., compressors, motors) for 5-10 years.
Check your warranty first! If your appliance is still under warranty, repairs may be free or heavily discounted. This makes repair the obvious choice.

Real-World Examples
A 3-year-old Samsung washer won't spin. Diagnosis: faulty lid switch ($120 repair). Replacement cost: $800. Decision: Repair. The appliance is young, the repair is inexpensive, and you'll get 7+ more years of use.
A 12-year-old GE refrigerator needs a new compressor ($650 repair). Replacement cost: $1,200. Decision: Replace. The appliance is at the end of its lifespan (13 years expected), repair is 54% of replacement cost, and a new fridge will be more energy-efficient.
The 50% Rule — Does It Still Hold in 2026?
The classic repair-or-replace rule says: if the repair costs more than 50% of a new unit's price, replace it. In 2026, this rule needs updating for Bay Area residents.
Why the 50% rule is outdated:
1. New appliance prices are up 18–25% since 2021 (supply chain, tariffs, energy efficiency requirements). A new mid-range refrigerator that cost $900 in 2020 costs $1,100–$1,400 now.
2. Delivery and installation fees in SF: $150–$300 typically. Haul-away of old unit: $50–$100 extra. In a 3rd-floor SF walkup with narrow stairs: add $200–$400.
3. Rebate programs: BayREN and PG&E offer rebates on Energy Star appliances. A washer replacement may qualify for a $100–$200 rebate, changing the math.
Updated Bay Area Rule for 2026
Repair if the repair cost is under 60% of (new unit + delivery + installation - available rebates). For luxury brands (Sub-Zero, Wolf, Miele, Viking), repair is almost always worth it at any age because replacement cost is $3,000–$15,000+.
