Frequently Asked Questions

Is the 50% rule still relevant in 2026?

Yes - adjusted for inflation but the ratio holds. The rule says: if repair cost exceeds 50% of replacement cost AND the appliance is past 50% of expected lifespan, replacement usually makes more sense. In 2026 you also factor PG&E rates ($0.30-$0.45/kWh in the Bay Area) - an inefficient 14-year-old fridge can cost $260/year to run versus $90 for an Energy Star unit, which shifts the math on older appliances toward replacement faster than the rule alone suggests.

Should I always replace an appliance that is over 15 years old?

No. Depends entirely on brand tier and repair cost. Premium brands (Sub-Zero, Wolf, Miele, Thermador, Viking) are engineered for 20-25 year lifespans - a 15-year-old Sub-Zero with a $400 repair is almost always worth fixing. Mid-tier brands at 15+ years with sealed-system or compressor failures usually do not pencil out. We see Sub-Zeros from the early 2000s still running on from $300 repairs every year.

Do home warranties affect the repair-vs-replace decision?

Yes - significantly. American Home Shield, Choice Home Warranty, Cinch, First American, and 2-10 Home Buyers Warranty all cover appliance repairs subject to a service fee (from $75). If your warranty covers it, repair almost always wins because your out-of-pocket is just the service fee plus any non-covered overage. Always check warranty coverage before paying cash out-of-pocket. We invoice most warranty companies directly when you provide a claim number.

Should I replace just for energy efficiency?

Only if the appliance is 15+ years old. For newer appliances, the energy savings from a new Energy Star unit (typically from $40/year) take 5-10 years to pay back the $800+ replacement cost. For 15+ year old refrigerators, the math accelerates because compressors of that era used 30-50% more energy. PG&E and BayREN offer rebates for qualifying replacements - check pge.com/rebates before deciding.

How long does a typical major repair take?

1-3 visits depending on parts availability. Same-day diagnostic. If common OEM parts are in stock (which we keep for ~80 of frequent failure modes), repair happens during the diagnostic visit. If parts must be ordered, expect 1-3 business days for mid-tier brands and 1-2 weeks for premium brands or older models. We never charge for the return visit.

Are extended warranties on new appliances worth it?

Usually not. Extended warranties from retailers (Best Buy, Lowe's, Home Depot) typically cost from $150 for 3-5 years of coverage. Most appliances either fail in the first year (covered by manufacturer warranty) or after the extended warranty expires. Self-insure by setting aside the warranty premium amount and using it for actual repairs when needed. Exception: built-in premium brand appliances where labor costs are very high - extended warranty math sometimes works there.

What is the longest you have seen an appliance last with repairs?

Twenty-8 years on a 1998 Sub-Zero 690 in a Russian Hill flat - still running on its original compressor with three relay replacements, two evaporator fan motors, and one door gasket over its lifetime. Premium brands really were built differently in that era. For mid-tier brands, an 18-20 year Whirlpool top-load washer with two transmission rebuilds is the maximum we see. Past that, parts availability becomes the limiting factor.

If I replace, will I save energy that pays back the cost?

For a 15+ year-old refrigerator at SF Bay Area PG&E rates, typical 5-7 year payback. For mid-tier dishwashers, washers, and dryers under 12 years old, energy savings alone rarely justify replacement - you are buying convenience or aesthetics, not savings. Use ENERGY STAR's Flip Your Fridge calculator (energystar.gov) for your specific model to see actual payback math before deciding.

Should I always get a second opinion before a major repair?

If the quote is over $600, yes. Second opinions cost $80 (our diagnostic fee) and protect you from misdiagnosis. About 25% of second-opinion calls we run end up with a different root cause than the first tech identified - same symptom, different failing component. For premium brands or repairs over $1,000, a second opinion is almost always worth the $80.

What if my repair fails after the warranty period?

Our 180-day warranty covers parts and labor for the specific repair performed. If the same component fails within 180 days, free replacement. If a different component fails after 180 days, that is a new repair (and we offer a returning-customer discount). We track every repair in our system, so when you call back, we already know your appliance history.
