Component Life Expectancies
Typical life expectancies for most components found in homes are listed below. These life expectancies have been determined through research and testing based on regular recommended maintenance and conditions of normal wear and tear, and not extreme weather (or other) conditions, neglect, over-use, or abuse. Therefore, they should be used as guidelines only, and not relied upon as guarantees or warranties.
Note: Life expectancy varies with usage, weather, installation, maintenance, and quality of materials. This list should be used only as a general guideline and not as a guarantee or warranty regarding the performance or life expectancy of any appliance, product, system, or component.
