Component Life Expectancy
These charts outline expected lifespans for appliances, materials, and components under regular maintenance and normal wear. Estimates are for reference only. They do not account for extreme weather, neglect, overuse, or abuse. A component past its expected lifespan is not automatically defective, and one within range is not automatically fine.
