Decision guideUpdated: July 21, 2026

When to repair or replace an appliance

A single percentage rule is not enough. The better decision combines repair cost with age, reliability history, warranty, safety, and replacement availability.

Core decision factors

What should influence the decision

Repair cost

Compare the full estimate, including labour, parts, taxes, and return visits, with a realistic replacement price.

Age and condition

Age matters more when the appliance also has rust, leaks, repeated faults, or unavailable parts.

Warranty

Manufacturer, retailer, credit-card, or extended coverage can change the economics.

Safety

A recall, fire risk, electrical damage, gas concern, or recurring leak can outweigh the cost comparison.

Prior repairs

Repeated failures suggest broader wear even when the current repair is affordable.

Replacement friction

Measure fit, installation, delivery, electrical or plumbing changes, and downtime.

A practical method

Use three possible outcomes

  • Repair favoredLower repair cost, useful remaining life, isolated fault, available parts, or warranty coverage.
  • Replacement favoredMajor repair, advanced wear, repeated failures, safety concern, poor parts availability, or repair near replacement cost.
  • More information neededNo reliable diagnosis, uncertain estimate, unknown age, or unclear warranty status.

Before approving a repair

Questions to ask the service provider

  • Is the diagnostic fee applied to the repair?
  • Is the estimate fixed or could more parts be added?
  • What warranty covers the labour and part?
  • Is the part new, rebuilt, or used?
  • Is there a known recall or service program?
