Yes, there may be exceptions to the life expectancy values listed in the ASHRAE chart. For example, equipment that is properly maintained, operated within design specifications, and protected from environmental stresses may last longer than the listed median value. Conversely, equipment subjected to extreme operating conditions, inadequate maintenance, or manufacturing defects may not last as long as the listed value. It is essential to consider these factors when using the ASHRAE chart to estimate equipment life expectancy.
