You bought a new air conditioner because it came with a 10-year warranty. A decade of peace of mind, you thought. Two years later, the company files for bankruptcy. The warranty? Worthless. The parts? Gone. You’re left with a broken machine and a bitter lesson: A 10-year warranty isn’t a promise of quality—it’s a bet that you’ll forget, or they’ll be gone.
This isn’t a hypothetical. Chinese air conditioner manufacturer Zhi Gao promised ‘lifetime free replacement of parts’ in 2002. It sounded like confidence. Customers loved it. Then the company restructured, assets were split, and those same customers couldn’t find anyone to repair their units. The stores disappeared. The factory said, ‘We’re bankrupt.’
Or take Fujitsu General, which once offered a full 10-year warranty on its air conditioners in China. In April 2025, after being acquired, the new owners slashed the warranty to 3 years for parts and 5 for compressors—the bare legal minimum. Some retailers still sell ’10-year warranty’ units, but now it’s a third-party insurance plan. When the company changes hands, your warranty changes too—and not in your favor.
Let’s be blunt: the real risk of an ultra-long warranty isn’t product quality. It’s whether the company will exist in a decade. The brands most desperate to offer a 10-year warranty are often the ones least likely to survive that long. Meanwhile, strong brands like Daikin and Mitsubishi Electric stick with the legal minimum—3 years—and still dominate the premium market. They don’t need to brag about warranties; their reputation does the talking.
You’ve probably noticed this pattern yourself. Think about the ‘lifetime warranties’ from electric vehicle startups like WM Motor, HiPhi, or Neta. They all promised lifetime guarantees. Then they went bankrupt or stopped production. No authorized service centers remain. Your warranty? Void.
Even established players play games. Xiaomi, the company now offering 10-year warranties on air conditioners, has a notorious track record with its phones: a common defect in the volume button causes random restarts. Xiaomi’s official service centers claim the parts are out of stock. Third-party shops fix it for $10. If Xiaomi can’t guarantee a simple repair for a common issue within a year, how can you trust it with a decade-long commitment?
The economics are simple. A 10-year warranty is a financial instrument: discount future service costs for immediate sales. The math works only if enough customers never claim, or if the company disappears before the claims roll in. That’s why some makers outsource the extra 4 years to insurance companies—a $14 policy on a $500 machine. You buy the card, activate it, and hope the insurer still exists when you need it.
So what’s the practical takeaway? Next time you see a 10-year warranty, ask yourself: Is this company strong enough to survive a decade without needing such a desperate sales gimmick? The answer will tell you more about the product’s quality than any promise on the box.
Stop being seduced by guarantees. Buy the brand that doesn’t need to promise you a decade—because its products already last that long.
FAQ
Q: But aren't 10-year warranties a sign of product confidence?
A: Not really. They're a sign of marketing desperation. The most confident brands—like Daikin or Mitsubishi—offer the bare legal minimum warranty and still dominate. Long warranties are used to mask weaker products or shaky business models.
Q: How should I evaluate a product's warranty when shopping?
A: Ignore the length. Look at the company's financial stability and track record. Check if the warranty is backed by the manufacturer or a third-party insurer. And remember: if a brand needs a 10-year promise to sell, its product probably isn't good enough to sell on its own.
Q: Could a 10-year warranty ever be genuine and safe?
A: Rarely, but possible if the company is a state-backed monopoly or has a captive service network that's legally obligated. For most consumer electronics and appliances, the risk of bankruptcy, acquisition, or policy change within a decade is too high. In practice, you're better off with a strong brand and a shorter warranty.
