Repair or replace? Appliances and systems

A simple rule of thumb, and when to break it.

5 min read

When an appliance or system breaks, the question is whether to fix it or start fresh. A rough rule helps.

The 50% rule of thumb

If the repair costs more than about half the price of a new one, and the item is past roughly half its expected life, replacing often makes more sense. It's a starting point, not a law.

Lean toward repair when

  • It's still under warranty
  • The part is common and cheap
  • It's otherwise in good shape
  • Newer models wouldn't save much energy

Lean toward replace when

  • It has broken several times recently
  • Parts are hard to find
  • A new, efficient model would lower energy bills
  • There's a safety issue
